Coordinates

The following coordinates correspond with sites featured on the Greater Nett & Western u Eco-Adventure Map Guide. It is our dream to eventually create a Pohnpei GPS app that could be uploaded to smartphones and other devices, but for now, these points of interest can be entered manually in a hand-held GPS device as needed.

NOTE: All GPS devices have a margin of error. That margin increases with interference — when there is a thick canopy of trees, during bad weather, or when mountains obstruct the satellite link. The geosynchronous satellites employed when navigating on Pohnpei are located low on the southwestern horizon, such that maintaining a strong connection while hiking on the northeast side of a given mountain range can be difficult. Coordinates on the northeastern slopes of mountains are less accurate than in other locations.

Pohnpei Diving – North Side Sites

“Manta Road”

Manta Rays at Manta Road in U, Pohnpei, Federated States of Micronesia (Photo by Whitney McCurdie)
Manta Road is easily Pohnpei’s most famous dive spot due to its resident community of manta rays (including the all-black Black Morph variety) that cruise back and forth through the narrow channel as they filter-feed. The site is located between the fringing reef at the north end of Mwahnd Peidak (island) and a long strip of reef running northwest-southeast (2.75 km southeast of Kepidauen Mwahnd). The mantas mate between January and April, which is a good time of year to visit. Aim for the last hour of the out-going tide a few days on either side of the full moon. The channel has very strong currents — up to 7 knots — (which the mantas love), but which make diving and snorkeling tricky. You’ll want to avoid the spot on flood tides. The water can be crystal clear, but usually there are more mantas around when the visibility isn’t very good. Huge schools of fusiliers and jacks, as well as black-tip and white-tip reef sharks are common in the area. Small turtles are occasionally spotted. 3-24 meters. Best at about 16 meters. Advanced.

  • Entering the MPA requires a permit. Visit our MPA page for details.

“Tubastrea Gardens”

This spot is located at a bridge about 17 meters down in the lagoon and about halfway between Parem and Mwahnd Peidak islands. The area is known for brightly-colored tubastrea (tube coral or sun coral) on the south side of the bridge. There are also a great many fish, though visibility is sometimes lacking. 15-20 meters. Best on an in-coming tide. Novice.

“Mwahnd Peidak”

This spot off the northeast side of Mwahnd Peidak’s fringing reef is notable for huge schools of parrotfish — a family of fish that is becoming relatively scarce in general. 3-18 meters. Best on an in-coming tide. Novice.

“Mwahnd Wall”

This drift-dive on the inner edge of the barrier reef south of Kepidauen Mwahnd is notable for the health and variety of corals and for reef sharks. The attractions go all the way down to 36 meters, which is where you’re most likely to find the sharks. Best on an in-coming tide. Advanced.

  • Entering the MPA requires a permit. Visit our MPA page for details.

“Mwahnd Pass”

This drift-dive on the west side of Mwahnd Pass (Kepidauen Mwahnd) is known for its whip coral, gorgonian fans (below 30 meters), tree coral, and macro life. It’s also a good place for eagle rays, reef sharks, crinoids, feather stars, and napoleon wrasse. The wreck of a catamaran lies at the edge of the channel. 3-30 meters. Best at 12-15 meters on an in-coming tide. Advanced.

  • Entering the MPA requires a permit. Visit our MPA page for details.

“Mwahnd Cove”

This drift-dive is on the southeast side of Mwahnd Pass (Kepidauen Mwahnd), beginning along the outer barrier reef wall and following the contour of the reef inside to a little coral bay dubbed “The Cove.” Attractions sometimes seen here include multitudes of mating eagle rays, moray eels, schools of barracuda (24 meters), whip coral, shrimp, and loads of white-tip reef sharks resting on the sandy bottom at about 30 meters. You might even be lucky enough to spot resident leopard sharks. 15-30 meters. Best at 24-30 meters on an in-coming tide. Advanced.

  • Entering the MPA requires a permit. Visit our MPA page for details.

“Inner Mwahnd”

This spot is on the inside edge of the barrier reef south and east of Kepidauen Mwahnd (pass). The coral is abundant on the wall. Reef sharks, barracuda, and plenty of reef fish are also found in the area. 3-20 meters. Best on an in-coming tide. Intermediate.

  • Entering the MPA requires a permit. Visit our MPA page for details.

“North Point”

Located at a sharp bend on the outside of the barrier reef, this wall dive is about sharks and large schools of pelagic fish. It’s quite a ways from any of the passes and the wind-exposed nature of the location means that the spot is only accessible during the summer. Down to 36 meters. Advanced.

“Lighthouse”

Sharks, pelagics, and more. This is a standard Pohnpei drift-dive that starts along the northern barrier reef wall and curves south into Kepidauen Pweitik (“Old Main Pass”). Best on an in-coming tide. Advanced.

“Lenger”

The areas north, south, and east of the Japanese seaplane ramp offer plenty for beginning divers. A variety of small reef fish, including gobies, angels, and parrots, octopi, sting rays, and lots of soft coral are found in the shallow coral grottoes. Visibility can range from terrible to very good. Best on a late in-coming tide. Novice.

“Parem”

This area on the fringing reef off the northwest end of Parem (island) offers more of the same kinds of attractions seen at Lenger. Visibility fluctuates greatly. Best on a late in-coming tide. Novice.

“Middle Pass” (Kepidauen Kiepw)

This spot is on the eastern corner of a narrow channel, called Kepidauen Kiepw, between Peinmen and Kepidauen Pweitik. The drift-dive starts on the outer edge of the reef wall and follows the reef south and east. This is a good place to see reef sharks. Best on an in-coming tide. Intermediate.

“Main Pass” (Peinmen)

This drift-dive begins along the northern edge of the barrier reef wall and follows the reef into Peinmen (Passage). Attractions include schools of black-tip and gray reef sharks (below 24 meters), occasional lemon sharks, schools of dog-tooth tuna, and sweetlips on the reef shelf at 24-30 meters. 5-30 meters. Best below 20 meters on an in-coming tide. Advanced.

“Sokehs Side Pass”

This little known spot in the narrow channel next to Peinmen is worth mentioning for the schools of large remoras that frequent the area. Best on an in-coming tide. Intermediate.

“Sandy Bottoms”

This blue hole on the inside edge of the barrier reef between “Main Pass” (Peinmen) and Palikir Pass (Kepidauen Palikir) is a great place for beginners to explore. Best on an in-coming tide. Novice.

“Palikir Bridge”

This is a deep dive that follows the reef bridge across the mouth of Kepidauen Palikir. It’s most famous for its schools of large pelagics, like tuna and wahoo, gorgonian fans, jacks, barracuda, humphead parrotfish, and huge schools of gray reef sharks. It’s also one of the places you might get a glimpse of Pohnpei’s little-seen tiger sharks. Currents can be strong. Best on an in-coming tide at 30-36 meters. Advanced.

“Palikir Wall”

This dive along the outer barrier reef wall west of Kepidauen Palikir is characterized by giant clams, triton’s trumpets, white-tip reef sharks, triggerfish, soft coral, and anemones. 9-37 meters. Best on an in-coming tide below 20 meters. Advanced.

Paddling in Nett, U & Northern Madolenihmw

Dausokele Estuary

As paddling goes in the Nett region, Dausokele estuary (“channel of the dwarves”) is the crown jewel, a long, gorgeous inlet that lies between Kolonia and the leaf-shaped Nett Peninsula and serves as the mouth of a number of high-volume rivers and streams. The scenery is stunning, especially on days where rain threatens, with high, sheer cliffs to the east, the heights of Dolen Nett in the north, and the pyramid-like peak of Dolen Eirike in the south. Depending on where you begin, you can go as far as 4.5 km (2.8 miles) inland before having to turn around. Most of the way, mangrove forests skirt the coast, so there’s nowhere to land and get out. The final 0.7 km (0.4 mi) follows meandering, narrow natural channels through the swamp forests, where you’re liable to meet locals and traditional outrigger canoes and young kids having a swim. The route tends to be well-protected from both currents and wind, so it’s a nice, leisurely paddle, allowing plenty of time to soak up the scenery. There are multiple places to launch on the Airport Causeway as well as the “Ice Dock” near the Kolonia Public Market building, and next to the PAMI building.

Nett Point

Another great paddling destination is Nett Point, Kolonia’s best swimming spot and the closest thing to a beach Pohnpei Island has to offer. Lidakika Launch point on the Airport Causeway is the most practical place to begin.

  • Visit the Nett Point page for detailed information about this location.

Dolen Nett Peninsula Circumnavigation

If you want to try something a little longer and more challenging, you can continue past Nett Point, explore the east coast of the peninsula (which includes one of the locations where the mythical builders of Nan Madol were said to have briefly settled), and then cross the beautiful little bay to the quaint picnic and swimming area at Awak Pah Marine Park. Note that strong winds can be a problem along the eastern coastal section. If you’re plan is a there-and-back-again, you’re looking at around 17 km (10.6 mi) round-trip.

Lenger & Sapwtik Islands

Two of the most interesting islands on Pohnpei are found directly north of Kolonia and can be reached quite easily via paddle-power. Both islands offer a wealth of Japanese fortifications from WWII and earlier, as well as other historical sites, swimming, and snorkeling.

Parem Island

The largest island in the northern lagoon is Parem, which is large enough to have its own elementary school. Like nearby Lenger and Sapwtik, the Japanese fortified the island prior to WWII. In fact, the coastal gun on Sokehs Mountain may have once been positioned at the top of Dolen Parem before being moved to its present location.

With the exception of a portion of the eastern coast, Parem is completely surrounded by mangrove forests — some of them quite extensive. There are two good channels to explore on the west side where the mangroves are at their widest — one 0.7 km (0.4 mi) long and the other 0.4 km (0.25 mi). Both reach all the way to solid ground at high tide and are beautiful places to scope out the local birds. You can also do a complete circumnavigation of the island, which is 7.9 km (4.9 mi) in total. On the east coast there’s a long stone wharf jutting out from the shore, suitable for a little break, a snack and a dip.

Nahnalaud — the Big Mountain

The Big Mountain

Hiking / TrekkingCave, Tunnel or BunkerWaterfallBird-WatchingCamping

The highest mountain in the Federated States of Micronesia (FSM) is called Nahnalaud (which means “big mountain”) and is located almost in the exact middle of Pohnpei Island. Pohnpeians consider the mountain sacred and regard it with respect and reverence, though most people have never been there because of the long, difficult hike involved. Local deer hunters and upland sakau farmers are the most frequent visitors to the highland region. A limited number of foreigners also attempt the summit.

In reality, Nahnalaud is not a single mountain but rather the highest peak in Pohnpei’s contiguous central mountain system, which separates the five chiefdoms. The primary central ridge runs from west to east and then curves north toward U not far beyond Nahnalaud. Additionally, a secondary ridge runs south, leading to Pohnpei’s second highest peak, Ngihneni, and then turning sharply to the west. The two ridges fence in the long, narrow Nanmeir Valley — the most remote region on the island.

The exact elevation at the Nahnalaud summit is a matter of debate as the survey methods used in the 1970s to map the island have a significant margin of error. The official number is 772 meters (2,533 ft), but the peak may actually be higher than that — likely close to 780 m. Ngihneni (“spirit’s tooth”) is nearly the same elevation (a difference of a few meters), which has generated a long-running dispute about which is actually the highest point. Nett, Kitti, and Madolenihmw have also argued about which chiefdom can claim Nahnalaud, but according to the municipal boundary lines on the 1983 USGS map, each of these municipalities has a piece of the peak.

Hikers should be careful not to underestimate the mountain. Though the distance is not extreme, the terrain is. Experienced trekkers will find all of the approaches challenging merely because of the very rugged nature of Pohnpei’s interior mountains. The concept of switchbacks is little known on Pohnpei; trails are rough, rocky, and often go straight up the slope. Hikers who plan to tackle Nahnalaud should be prepared to walk along narrow ridges with steep slopes on either side; cross jumbles of broken, slippery rocks; ford medium-sized rivers (particularly on the Nett and Madolenihmw routes); walk in shallow, rocky riverbeds; ascend and descend slopes of 50 degrees or steeper; wade through muddy mires; cross slick logs; and push through high grass or ferns.

Despite the difficulty in getting to the top, the trip is well worth it. Those who have never visited a cloud forest before will be awed by the otherworldly beauty of the ridge, a perpetually dripping wonderland of stunted, hoary trees, air plants, and bryophytic growth. Virtually every surface is covered with a thick layer of spongy golden moss and the ground is composed of layer upon layer of damp, decayed matter. The area, which never dries out, gets at least 8.3 meters (325 in) of rain every year and is shrouded in thick fog much of the time, making clear views from the summit a rare occurrence.


Pehleng Approach (Western Kitti)

Hiking along the central ridge east of Pehleng, Pohnpei, Federated States of Micronesia (FSM)

This well-defined trail up to the primary ridge and eventually to Nahnalaud was first promoted in 2013 by a local business calling itself Pohnpei Trailways. The idea was that this trail, starting in Pehleng, could be hiked by tourists without the assistance of a local guide. We strongly recommend that you do NOT do it that way. In fact, we think it’s a very a bad idea. Though at the time of writing (2014) the entire length of the trail was marked with pink flagging tied to tree branches, there is still plenty of potential for visitors to go astray. Furthermore, accidents or injuries without a local guide present could result in disaster. Remember that Pohnpei has no search and rescue service.

The true ascent begins after passing through a cluster of houses (ask permission) 0.95 km beyond the trailhead. After that, the trail is wide and true as it climbs steadily for 1.45 km (20% slope average) through the forest to the open fern meadow atop Dolen Salapwuk (510 m), where there are some good views in clear weather. The trail then re-enters the forest and begins to climb again for 4.6 km (13% slope average), narrowing as it comes up to the main ridge (696 m). Just before Shelter 1 (Dolmweir), there’s a 315 meter-long segment that is less than a meter wide with precipitous slopes on both sides; we’ve dubbed it the “Knife Edge.”

Shelter 1 is located at Dolmweir, where an appendage of the mountain thrusts north from the main ridge. There is no flowing water nearby. The privy is located 22 m to the north. After Shelter 1, the trail descends steeply by about 62 m on the south side of the ridge and skirts the base of a rocky cliff before climbing back to the ridge-top. From there it goes up and down for 2.94 km before reaching Mountain Shelter 2 roughly 5 minutes below the Nahnalaud summit.

  • Plan for 5-7 hours from the trailhead to Shelter 1 and 3-4 hours from there to the summit.

NOTE: As of February 2014, the pandanus-thatch roofs of the two ridge shelters were in very bad shape, heavily deteriorated and leaky. Plan accordingly.

The Origin of the Yap Banana

In the westward land of Sapani, a woman named Lienpwel (“woman of earth”) had two daughters, Lisoumokaiap and Lisoumokalang. The daughters decided to take a canoe and look for new land in the east and brought with them some “underworld yams”, banana shoots, and a stone called the Stone of Sahwar. The sisters eventually landed at a place in what is now Pwoaipwoai district (at that time the island was smaller and Pwoaipwoai lay near the coast). There they placed the stone and planted the yams. The stone was highly reflective, and when the sun would hit it, it would shine brightly (hence the name Sahwar, which means “shining” or “flashing”).

The younger of the two sisters, Lisoumokalang, eventually returned home to Sapani. On the way she visited the islands of Yap and propagated a new type of banana, which thrived and became the tallest of all banana varieties. Some time later, a Pohnpeian man who lived in a place called Loangen Kitti was looking west toward the sunset and he saw the tall banana plant in the distance. The ripe fruit were attracting many birds, so he found two starlings – one a common Micronesian starling (sioahk) and the other a Pohnpei mountain starling (sie) – and he took them up to a high mountain in Pehleng. The Micronesian starling was a lazy flier, but the mountain starling was clever and efficient. He sent both flying toward Yap. The Micronesian starling was distracted on the way and diverted from its course. Only the Pohnpei mountain starling reached its destination. It joined the other birds in eating the bananas, and while it did so, a seed became lodged in its feathers. Both birds eventually flew back to Pohnpei and landed at the peak of Pekenuht (which, appropriately, means “banana feces”). The seed carried by the mountain starling fell to the ground and propagated utin iap (the Yap banana).


Enipein Powe Approach (Kitti)

Twisted tree-life on the central ridge north of Enipein, Pohnpei, Federated States of Micronesia (FSM)
This route begins at the end of an unpaved road in Enipein Powe and climbs gradually on a well-defined footpath up an out-thrust from the southern ridge. At the top, the trail passes through a saddle between Nahnan Pwoaipwoai and Dolen Uhd, then descends slightly along the inside of the ridge slope, finally arriving at a massive overhanging rock known by local guides as “the cave.” The cave has nice views through the trees of the Nanmeir Valley at the Lehnmesi River source below. You can also see Nahnalaud to the northwest and make a guess at the direction of Ngihneni to the east. The cave is an excellent place to camp with a cushioned fern-lined floor (that stays dry in wet weather) and usually some dry firewood stowed by hunters in the vicinity (replace what you use).

From the cave, the trail continues along the inner slope below Ngihneni, crosses several small streams, and then climbs steeply (20% slope average) to the top of the main ridge. At this point it’s just a short walk west along the ridge path to the first open viewpoint near a USGS benchmark. The spot people typically consider to be the summit is 5-10 minutes further, and Shelter 2 is just below that.

  • Plan for 6-8 hours from the trailhead to the cave and 90 minutes to 3 hours from there to the summit.


Salapwuk Approach (Kitti)

There are many ways to Nahnalaud from Salapwuk but they all begin at the end of the road beyond Salapwuk Elementary School. The early part of the hike uses the same trail as the Six Waterfalls, but at the place where one would turn toward the river to encounter Falls #1 (Pahnairlap), one instead follows a trail going northeast. This trail stays north of the river, crossing above Iro, Nan Emp, and Lipwentiak waterfalls. The latter is the most spectacular, located where the river gets funneled into a narrow channel and makes a hairpin turn. According to legend, this feature of the river was created when the matriarch of the Great Eel Clan encountered an eel hunter and writhed violently in horror at the sight of the dead eels he was carrying. Small pools above the falls are home to Pohnpei’s endemic freshwater shrimp, which the guides might be willing to catch for dinner. After that, the trail only meets the river again twice, where it cuts through a wide loop in the watercourse. It then turns north and climbs 362 meters in elevation to the primary ridge, not far from the summit.


Nanipil Approach (Nett)

Foggy forests on the Nanipil approach to Nahnalaud, Pohnpei, Federated States of Micronesia (FSM)
Though slightly shorter, the Nanipil approach to Nahnalaud is certainly challenging. It’s significantly steeper than the other routes (except Salapwuk) and the trail is not well-maintained once you reach the rear of the valley. The hike starts at the house next to the hydroelectric building at the end of Nanipil River Road. Immediately behind the house, hikers must cross a river and then shortly after that a small stream. An easy segment follows with a well-defined residential path leading to the last house in this part of the valley (1.39 km), where an old man lives alone.

Past the house, the route continues on a fairly well-defined path that crosses the river several times (these crossings can be tricky if there has been a lot of recent rain). In a few places, you have to walk in the river itself, which can be quite difficult given the slickness of the rocks. Finally, after 2.94 km (3% slope average), the trail begins to climb out of the valley on the east side of the river and follows a sub-ridge up from there (3.16 km with a 22% slope average).

The climb has several pitches with small, flat rest areas in between. The first stop has a conspicuous tree of gigantic proportions entwined with vines almost as massive. The second stop is frequently used as a camp site by hunters and is one of the few places on the mountain with mobile phone reception. The final segment leading to the primary ridge is steep and often muddy. In places it follows the natural pathway of small streamlets (keep an eye out for a small waterfall high up on the slope). Once reaching the main ridge (754 m elevation), it’s an easy 0.56 km walk east to Shelter 2, a typical nahs-style thatched hut that can sleep ten or so.

NOTE: As of February 2014, a large part of the roof of this shelter had rotted away, leaving the central part of the hut exposed to the elements.


Nankepinmerepw Approach (Madolenihmw)

Nankepinmerepw valley, Pohnpei, Federated States of Micronesia (FSM)

This route passes through the gorgeous valley of Nankepinmerepw, following the upper tributaries of the Nan Riohk Stream and eventually arriving north of Nahnalaud on an arm of the primary mountain system.

The hike begins at a rutted turn-off from the well-graded (but unpaved) road to Pahn Sile Waterfall, leads to a metal footbridge over the Senipehn River — the only bridge like it on the island — and connects with a path on the far side. From there, the trail meanders northwest not far from the Nan Riohk and more or less parallel to it.

The first kilometer or so cuts through cultivated lands. Then it begins to follow the water more closely as it passes into the wilder riverine forests. There are at least nine major stream crossings in this next segment, some of which may be difficult or impossible if there has been a lot of recent rain. Above the last major Nan Riohk tributary, where the name of the stream changes to Nankepinmerepw, hikers take to the stream bed itself, which is certainly the most challenging aspect of the route (13% slope average). The algae-slimed rocks are slick and dangerous and hikers may find that they have to go very slow and use both hands to avoid disastrous slips; it would be easy to snap an ankle or shatter a kneecap in this place. Despite the rough terrain, the scenery in this narrow valley, often fenced on both sides by high rocky walls, is terrific. At times, the trail passes along the tops of vertical prismatic basalt columns.

The first few points of interest are beautiful pools that will tempt any overheated hiker — and why resist? A bit further is a small waterfall near a prismatic basalt quarry site for Nan Madol. Abandoned prisms can be found lying in the stream bed in several places — the largest just below the falls. How exactly prisms were hauled down to the coast from this site is anyone’s guess. After a short, steep section (22% slope average), the valley terminates at a huge “horsetail” waterfall that the route crosses above (you can scramble down the eastern slope without too much difficulty for a better view from the side). The shallow pools above the falls are also an excellent place for a look at Pohnpei’s native crayfish.

Past the big waterfall, the stream narrows until it reaches a third waterfall — this one short and wide, falling over a straight lip (usually called a “block falls” or “sheet falls”) — and then diminishes to a trickle. From this point, the hike climbs west (29% slope average) and then south again as it follows the ridgeline (18% slope average) toward the Nahnalaud summit.


How Long Will It Take?

Though it is possible to hike up and down Nahnalaud in one day, as we did during one of the many data-gathering excursions, we don’t recommend that you put yourself through that kind of torture. Hiking to Nahnalaud should be considered a 2-day affair with one night spent either at the cave, one of the mountain shelters, or somewhere else on the ridge. Inexperienced or out-of-shape hikers may need three days or more.

Hiring a Local Guide

All of the routes up to Nahnalaud require an experienced local guide.

You should offer your guide no less than $160 if there are five or less in your group and at least $220 if there are more than five (plus tips). If you do the math, you’ll see that this is quite reasonable. With five people, each hiker pays just $32 plus tips — a super bargain. If you can’t assemble a group, you’ll still only pay $80 per person with two hikers, which is less than you’d pay for two dives at virtually any SCUBA company in the world (and this is two days and one night). Obviously, if you plan to take a slower pace and do the hike over three or more days, you’ll need to pay your guide more.

Your guide is your lifeline; you will depend on him to keep you safe and on the right track throughout the duration of your hike. Guides provide other useful services as well, such as making campfires in damp weather. If you expect your guide to cook meals for the group or carry any gear for you, he should be paid extra. Agree on a price beforehand.

Dolen Nahnsapwe

Hiking / TrekkingBird-WatchingCamping

Dolen Nahnsapwe, “hill of thunder,” is a small peak near the NettU border. As the crow flies, it’s about 1.3 km (0.8 mi) southwest of the Kupwuriso summit. Though rarely visited and not the highest point in the area, Dolen Nahnsapwe is intriguing because it’s associated with stories about the traditional thunder god, Nahnsapwe, and is said to be the place where thunder storms originate. It’s also the source of the Pwong-Kapwungapwung watercourse, a stream that forms a waterfall below the Lou Rahn ridge in Nett. It’s a challenging climb that follows a trail only part of the way, but the pay-offs come in the form of soaring vistas and gorgeous upland forests. You can approach the peak from either Nett or U or do a full traverse (6.75 km / 4.2 mi) from one side to the other.

Nett Approach

The Nett approach to Dolen Nahnsapwe feels wilder and is steeper and more strenuous. It begins on the side of an unpaved road in Paremkep. The first 0.6 km (0.37 mi) follows the same track that goes to Lou Rahn waterfall and cave with a gentle slope average of about 12%. After that, it branches off and climbs more steeply along the Lou Rahn ridgeline for 2.65 km (1.65 mi) with a slope average ranging between 20% and 25%. This brings hikers to the foot of the peak — a swampy area dominated by thickets of kotop (Clinostigma ponapensis) palms.

U Approach

The way up from U begins behind a cluster of houses at the end of the last road before the Madolenihmw border. On this side, things are much more developed and the trail is clear and well-maintained nearly to the top of the pass north of the peak. One conservation worker told us that sakau farmers from U frequently use this route to access illegal plots in the watershed on the Nett side. The 3.2 km (2 mi) trail meanders through inhabited areas and past a number of a small huts and residences (23% slope avg).

The last bit up to the tiny summit (593 m) is an over-grown, steep (46% slope avg), grubby, and sometimes unnerving scramble from the northwest side. The summit is tiny, and the ground up there has a springy, unstable feel as if you’re actually standing on layers upon layers of ferns and moss rather than solid ground — which may be the case. The effort and unease, however, are rewarded with a truly marvelous 300-degree view. Sokehs Mountain (276 m), Kolonia Town, the open summit of Kupwuriso (630 m), and Dolen Saldenre (629 m) are all visible — weather permitting.

You can do this climb as a day-hike, but a better option is to camp somewhere along the upper Pwong Stream (Pilen Pwong). Remember to pack out everything you packed in. A responsible camp site is one that is invisible once its occupants depart.

  • Plan for 8 hours for this hike.

Nett Point

BikingSwimmingSnorkelingKayaking / CanoeingPicnickingBeaches

Nearly all of Pohnpei’s coastline is surrounded by mangroves, and though these otherworldly swamp forests are incredible to explore by kayak, canoe, or paddleboard, they tend not to make good swimming spots. As a result, Nett Point — a long man-made strip of dredged coral and concrete at the north end of the Nett Peninsula — is currently the closest thing Pohnpei Island has to a beach. During the American Period, the place used to be the primary commercial dock. Supply ships would anchor at the end and a barge would carry cargo into Kolonia Harbor (the barge now rusts on the edge of the mangroves just south of Nett Point). The problem, however, was that lots of shallow reefs made Kolonia Harbor and the areas in the lagoon to the north risky for ships to navigate through. Sokehs Passage (Peinmen), to the west, was deeper and better protected. Once the modern commercial harbor and dock were established on the west coast of Dekehtik Island and big ships started using Peinmen (now called “Main Pass”) instead of Kepidauen Pweitik, Nett Point was abandoned. Over the years, the buildings and dock have been used for a variety of purposes, including storing outrigger canoes for the Nett paddling team and, most recently, as part of a clam hatchery operation. However, the point has simultaneously been a popular swimming and picnicking location for decades. The dock area has nice deep water for serious swimming and jumping and the sandy man-made beaches are perfect for kids. Some of the large trees overhanging the water have ropes attached that local kids like to swing around on. If you start near the dock and swim out along the edges of the nearby reefs, you can find some decent snorkeling. Many people barbecue on the east edge of the causeway or on the dock. Overall, Nett Point is a great place to swim, relax, and get to know some locals on a sunny day. Shade is scarce, so bring a hat. Depending on tides and recent rains (best during mid to late in-coming tide), the water is usually clean and clear with a visibility of more than ten meters.

In 2011, the Office of Tourism and the Nett Municipal Government attempted to improve the spot by cleaning it up, dumping large quantities of white sand along the western edge of the causeway, and planting trees. Further developments were announced — sand volleyball courts, public restrooms, and more were said to be in the works and it was announced that the municipality would be charging a small entry fee. After several accidents involving local boats and swimmers, a new channel was dredged not far away and all traffic was encouraged to completely by-pass the areas where people swim. When boats continued to zip through the channel without regard to people in the water, a buoy line was finally placed at the north entrance to the channel and the south end was partially blocked by a causeway. Though these changes solved the boat problem, they created another — inhibiting the natural flow of the tide through the area and reducing the water quality significantly. A small set of outhouse-style restrooms were eventually slapped together near the main road, but these were quickly destroyed by local kids. No fee was ever charged, and it’s unclear how the money would have been collected anyway. Things are very much still in flux. What Nett Point will look like in the future is anyone’s guess.

  • It’s easy to spend a 4-6 hours at Nett Point, when the conditions are good.

Nan Koropwung Cliff & Caverns

Hiking / TrekkingCaveWaterfallBird-WatchingCamping

Prismatic basalt wall at Nan Koropwung, Pohnpei, Federated States of Micronesia (FSM)

Anyone who takes a good look at the mountains on the eastern border of Nett will note a dark patch of naked basalt amid the otherwise unvarying green of the steep hillsides. This is the cliff-wall and caverns of Nan Koropwung. The trail to this spectacular and little-known site begins at the end of the unpaved but well-graded road in Paremkep and meanders up the heavily-wooded slope with some rather steep and brushy sections. Eventually, one comes to a towering wall of prismatic basalt columns overrun by a waterfall, which can be dramatic after heavy rain, but is most often thin and misty. Below the falls, the bare rock is in the process of decomposition, smooth and crumbly.

The first 164 m / 180 yd (12% slope avg) from the trailhead brings hikers to a small sakau hut in the woods. The narrow stream crosses the path 57 m (62 yd) further (16% slope avg). After that, the path fades into obscurity and it’s a challenging 489 m (0.3 mi) bush-whack scramble to the cliff and waterfall (47% slope avg). That’s not the end, however, by a long shot. If you pick your way across the rocks under the falls and along the slope for about 80 m (87 yd), you’ll come to the first cave of three. Partially hidden by a curtain of vines, this cave is well-protected from the elements and makes a good campsite. There are great views of Nett and Kolonia and some flat, dry ground.

About 130 m (142 yd) further is a second cave — this one forming a low, tunnel-like passage parallel to the hillside. Swiftlets nest on the roof and their guano covers the floor. Scramble through and you find yourself in the final cave, which is like a bay window looking out over the serene landscapes of Nett and eastern Sokehs. There’s really nothing like this spot on the island. Take care, however — the cavern opens onto a sheer (certainly fatal) drop to the valley below.

  • Plan for 3-6 hours for this hike.

Dolen Eirike

Hiking / TrekkingWorld War II FortificationsBird-WatchingCamping

Dolen Eirike (“hill of Eirike”) is a prominent pyramid-shaped peak in Eirike district at the rear of Nett — easily visible from Kolonia and standing out from everything else as one drives south from the coast.

The ascent to the summit makes for a nice half to full-day excursion. A paved road runs through Kahmar, crosses the Pilen Kahmar bridge, and then climbs up and along a low ridge in Eirike before dipping back down again. Along the drive, you’ll pass rows of gorgeous Mindinao gums and Terminalia carolinensis trees (a species found only on Pohnpei and Kosrae) and several spots with wonderful views of the river valleys on both sides. The Eirike road, however, has some bad spots near the turn-off, so you’ll need to go slow and have a vehicle that isn’t too low to the ground.

The trailhead is located at the end of the paved road just beyond the last house and at the foot of the mountain. During the Japanese period, Catholic missionaries working in Kolonia were forceably relocated to a camp in this vicinity, though it’s not clear exactly where. Now the area is mostly small farmsteads, sakau plots, and jungle.

Giant wild banana plants on the slopes of Dolen Eirike, Pohnpei, Federated States of Micronesia (FSM)

The well-trodden lower 0.28 km (0.17 mi) of the trail winds upwards through large areas of sakau cultivation with an average slope of about 23%. As you begin to move above the cultivated areas, the forest thickens and provides cover from the sun but not much relief from the stifling heat. The rest of the climb to the summit is a pretty consistent slope of about 38%. Giant tree ferns with blood-red sap, wild banana plants (utin wel), elaeocarpus, and ivory nut palms are abundant on the slopes.

Slightly less than a half kilometer from the top, you’ll pass a series of Japanese World War II trenches that cross the path. Historical records seem to indicate that anti-aircraft guns were also installed nearby, but they aren’t there now.

The summit itself is often overgrown, but you can get some nice views of Kolonia Town and Sokehs Island through the trees. There’s plenty of flat ground for a campsite and enough trees for protection against any wind.

  • Plan for 4-8 hours for this hike.
  • Please visit the Local Guides & Tour Operators page for a list of experienced guides available for hikes to Dolen Eirike. Offer $25-50.00 for a group of five or less.

The Story of the Tree of Nansokele

Eirike was part of the ancient region of Nansokele before the chiefdom of Nett split off from Sokehs. As is told in one famous legend, shortly after the fall of the Saudeleurs, some men were trying to cut down a large Terminalia carolinensis tree (kehma) near Dolen Eirike with the intention of building a canoe. No matter what they tried, however, the tree would not fall down. The high priest of Wene was called for and used a special adze to chop through the stubborn trunk, but instead of toppling over, the tree rose up and vanished into the clouds. Soon after, word spread that a canoe made from the wood of the same tree had descended from heaven and hovered over the ocean at a spot near Temwen Island (Sounahleng). The people took this to be a divine omen, and a great meeting followed at Poasoile on Temwen Island, where the paramount chief system that exists today was established.

Nan Kiepw & Na Malek

Nan Kiepw

Hiking / TrekkingCaveWaterfallBird-WatchingCamping

Nan Kiepw

Nan Kiepw beauty, Pohnpei, Federated States of Micronesia (FSM)
Nan Kiepw, which means “in the lilies,” is a hillside overshadowed by Dolmweir peak. A Pohnpeian myth tells of a Yapese magician, named Sou Iap, who voyaged to Pohnpei and was responsible for the creation of Sokehs Rock). One of Sou Iap‘s companions, Souliken And, noticed a girl collecting clams on a reef north of Sokehs Island, and thinking her very attractive, chased her deep into Nett, carrying an ihd leaf with him. On the hillside below Dolmweir peak, Souliken And lost his leaf and named the place after a species of white lily he saw there.

During the Sokehs Rebellion in 1910, Pohnpeian rebels fleeing from German and Melanesian troops briefly took refuge at Nan Kiepw, rebuilding some earthen fortifications from the Spanish Period and repelling a small attack.

Today, Nan Kiepw maintains a pristine beauty that betrays no sign of past violence. A tributary of the Nanipil River (Pillapen Nanipil) runs through the area, forming a wide gentle cascade, some small pools (though none big enough for swimming), and a “horsetail” waterfall before winding into the valley. Upstream is a basalt outcropping — really a great boulder — that forms an overhang where a few people can comfortably camp out of wind and rain. Huge ivory nut trees, red sandlewood, and a variety of hardwoods dominate the lush native forest, and there are many unusual varieties of fungi to be seen.

The Origin of the Ivory Nut Palm

On the fourth voyage to Pohnpei after its founding, a man came named Mederiap, bringing with him the ivory nut palm and propagating it on the island. Prior to this time people had mostly lived in caves, because they had nothing to use for roofing material, but ever afterward, the fronds of the ivory nut palm were woven together to produce roof thatch for houses.

The moderately challenging trail begins behind a house near the Nett hydroelectic building at the end of the Nanipil River Road (the same trailhead for Nahnalaud). Hikers cross the Nanipil River directly and walk along a well-maintained footpath for 0.99 km / 0.61 mi (5% slope avg) before coming to the first major branch. The left (east) branch leads on toward Nahnalaud, while the right (west) branch heads to Nan Kiepw. From this point it’s 1.4 km / 0.87 mi (14% slope avg) to the last residence along the trail at 265 meters of elevation, and then another 1.8 km (1.12 mi) to the waterfall. This last segment has two little ascents with slope averages of about 20% and 26% and a more moderate bit in between (11% slope avg). Sakau (kava) plantations are found on both sides of the trail much of the way. Hikers should take care to avoid damaging these valuable plants.

Adenanthera pavonina (Red Sandlewood), Pohnpei, Federated States of Micronesia (FSM)

Crab’s Eye Vs. Red Sandlewood: What to Know and Why it Matters

Two species of trees found both in inhabited areas and in the upland forests of Pohnpei produce small brilliant red seeds about the size of popcorn kernels. These can be seen scattered across the forest floor and often on the trail leading to Nan Kiepw. Red seeds with a single black dot on them belong to Abrus precatorius (Crab’s Eye Seed or John Crow Bead), while solid red seeds come from Adenanthera pavonina (Red sandlewood). The first type of seed (with the black dot) contains a compound, called abrin, that is 75 times more toxic than ricin and can be fatal if ingested; the fatal dose is about 0.1 mg for an adult of roughly 68 kg (150 lbs). Symptoms of poisoning include nausea, vomiting, convulsions, liver failure, and death after several days. The second type of seed (all red) is harmless when cooked and is sometimes eaten as a snack by Pohnpeian children. Strangely, the same Pohnpeian name — kaikes — is used to identify the two species of trees. Both Abrus precatorius and Adenanthera pavonina originate on the Indian subcontinent. Seeds are sometimes used to make necklaces and other jewelry.

Na Malek overhang, Pohnpei, Federated States of Micronesia (FSM)

Na Malek

Na Malek (“his chickens”) is a rock overhang and cave — located in the part of upland Nett once known as Nansokele — said in myth to have been the home of the demon Taimuan. The site, which has excellent views of the valley, Dolen Eirike, and Dol Rakied, is reached via a steep loop of path (0.61 km / 0.38 mi with a 42% slope average) that branches off from the Nan Kiepw trail. The overhang is large enough to provide a protected camping spot, and the elevated cave is bone-dry, flat-floored, and suitable for sleeping. Water running off the rock can be filtered for drinking. This is a relaxing and beautiful place to watch birds, including the Grey White-eye and rare Long-billed White-eye.

  • Plan for 8 hours for both Nan Kiepw and Na Malek.
  • Please visit the Local Guides & Tour Operators page for a list of experienced guides available for hikes to Nan Kiepw. Offer $50.00 for a group of five or less.

The Tale of Taimuan

A well-known Pohnpeian myth states that Na Malek was the the home of a hideous old demon, named Taimuan, and his sister, Litapinmalekelek. Taimuan had a hankering for human flesh and was, in particular, interested in the beautiful daughter of the Saudeleur — the supreme ruler that reigned from Nan Madol. Deciding that he wished to devour the girl, Taimuan set out for Nan Madol, transforming himself into a handsome young man along the way and leaving his old parts at different points in the mangroves — his white hair, swollen legs, swollen testicles, sagging eyelids, etc. When Taimuan arrived at Nan Madol and presented himself to the Saudeleur, both the girl — who was called Kisin Ntamwahu (“a little bit of good blood”) — and her father were impressed with the young suitor. Kisin Ntamwahu fell for Taimuan and begged her father to let them marry. Soon the two were married and given a home on Pahn Kadira.

After residing at Pahn Kadira for a while, however, Taimuan obtained permission from the Saudeleur to take Kisin Ntamwahu back to Na Malek. On the way, he picked up all his old parts from the mangroves and was restored to his prior appearance. Kisin Ntamwahu realized she had been tricked, but Taimuan carried her away against her will and confined the girl inside the cave at Na Malek. Then he climbed to the top of the mountains to invite all the other demons in the area to join him in feasting on the girl. While he was away, his sister, Litapinmalekelek, discovered Kisin Ntamwahu and felt sorry for her. She began to dig the girl out of her prison and encouraged Kisin Ntamwahu to turn herself into an ant, in order to escape, and flee into the forest. She warned the girl not to pass any plants without greeting them politely. As Kisin Ntamwahu ran, she greeted all the plants, big and small. All except one. Feeling a sudden need to urinate, she relieved herself in the forest and didn’t realize she’d done so on a plant called kampanial.

When Taimuan found that Kisin Ntamwahu was gone, he confronted Litapinmalekelek, but she claimed to know nothing. In a rage, Taimuan showered his sister with obscenities (specifically, he shouted, “Your vagina! My penis!” — a highly offensive reference to an act of incest) and then took off into the forest to catch Kisin Ntamwahu. He questioned each plant he passed, but none would tell him anything until he came upon the kampanial, which told Taimuan which way Kisin Ntamwahu had gone. Shortly thereafter, Taimuan met two worms on the path. He asked them where the girl had gone and they promised they would tell him if he pulled down his eyelids. He did so, and the worms threw dirt in his eyes. When Taimuan tried to wash his eyes out in a nearby streamlet, the worms muddied the water upstream, causing him to go blind and eventually die.

Lou Rahn Cave & Waterfall

Hiking / TrekkingCaveWaterfallBird-WatchingCampingSwimming

Tucked away in the little-seen Nett hinterlands is one of Pohnpei’s most beautiful hiking destinations. Uluhlen Lou Rahn, a fence-like ridge, extends northwest from the place where the mountains of U meet those of Nett, hiding from view the verdant valley of the Pwong Stream (Pilen Pwong). Cutting through this gorge from its source below Dolen Nahnsapwe, the stream spills over a high cliff to form a thundering waterfall next to a large cave with a view of the misty valley floor. Though there is no quick way down to the bottom of the waterfall from the cave (you can backtrack a ways and make your way down the slope to the stream), there is a gorgeous pool for swimming just up-stream with cool, crystal-clear water.

Sakau (kava) at Lou Rahn, Pohnpei, Federated States of Micronesia (FSM)

The trail to the site begins off the unpaved but well-graded road in Paremkep and sees plenty of traffic from sakau farmers and residents on the first 0.6 km (0.37 mi) leading toward the spur (12% slope avg). Once it reaches the ridge, it cuts east and passes along Lou Rahn’s inside slope rather than following the ridgeline (0.92 km / 0.57 mi, 19% slope avg). The hardest aspect of this full-day hike is the treacherous footing, as much of the last leg of the route crosses the sharp, jumbled rocks of old landslides now obscured by high grass. Take care and watch each step; a fall into one of the hidden crevices could result in a serious sprain or fracture — not a good thing to have way out in the forest on Pohnpei. There are also a great many sakau (kava) plants in the area — a massive number, in fact — which hikers must take care to avoid damaging. The roots of the plant are used to make Pohnpei’s potent ceremonial drink. Large plants can be twenty years old or more. Small huts, which farmers use while working on their plants, are passed at several places along the route.

The cave sits just to one side of the falls with a stunning view of the hidden valley. The roof is a bit low in places, but it’s quite a fair size none the less. Though a thin stream of water flows across one side of the cave floor, the rest is dry and makes an excellent camping location. Hunters often use it, and you may notice their cooking pots stored in crevices at the rear of the cave.

  • Plan for 6-8 hours for this hike.
