rainforest – Pohnpei Eco-Adventure Guide

An Introduction to Pohnpei

Pohnpei, the Ultimate Adventurer’s Paradise

Imagine an island that still retains its wildness — a place of rugged, breathtaking beauty, vibrant traditional culture, unpaved remoteness, and mystery. Imagine a landscape so green that it threatens to burn a hole in your retina. Picture being the only snorkeler on a pristine reef, surfing one of the world’s most celebrated waves, diving in a place most divers have never dreamed of, climbing misting mountain peaks, exploring a prehistoric megalithic city, or trekking through lush rainforests. This, in a nutshell, is Pohnpei.

But, Where the Heck is It?

The short answer? 4,828 kilometers (3,000 miles) southwest of Hawaii and 3,700 kilometers (2,300 miles) northeast of Australia. Pohnpei is the largest and highest island in the Federated States of Micronesia (FSM), a far-flung oceanic nation with some 600 islands spread across a vast section of the western Pacific between Hawaii and the U.S. Territory of Guam. The FSM is one of the most culturally diverse areas in the Pacific with more than twenty distinct groups and as many unique languages. The country is divided into four states (from east to west) — Kosrae, Pohnpei, Chuuk, and Yap. The capital of the FSM is located at Palikir on the west side of Pohnpei Island. In addition to the main island, Pohnpei State also includes four inhabited Micronesian atolls, two distant Polynesian outliers, two uninhabited atolls, and a submerged atoll.

They Don’t Call It the Garden Isle for Nothing

Roughly 22.5 kilometers (14 miles) in diameter, Pohnpei Island is the peak of a 5 million-year-old extinct shield volcano that has subsided over its lifetime. Some say it bears a resemblance to Bora Bora minus the unchecked development. Others liken it to something out of a Robert Louis Stevenson novel. Both would be correct. The place is rugged and brilliant green with a dense rainforested interior and mountains as high as 780 meters (2,600 feet). With 825 centimeters (325 inches) of rain a year in the interior, Pohnpei ranks as the seventh rainiest location on Earth. All that water adds up to more than 40 watercourses, scores of scenic waterfalls, and some of the largest areas of intact upland rainforest in the Pacific.

Pohnpei offers divers and snorkelers a mostly unexplored marine wonderland

A Marine Wonderland

Pohnpei’s coasts are entirely encircled by shadowy mangrove forests that are more than 3 kilometers (2 miles) wide in places and provide a maze of narrow, tunnel-like channels for kayaking, canoeing, or stand-up paddleboarding (SUP) enthusiasts. This environment is a serene domain of birds and other creatures. A half to one and a half kilometers further out, a barrier reef curves around 70% of the island, forming a large, placid lagoon with passages going out into the open ocean — prime spots for surfing, snorkeling, and SCUBA diving. Small volcanic islands are scattered about within the lagoon and coralline islands with sandy beaches perch along the reef itself, calling to campers and beach-bums.

In short, there’s a little bit here for everyone . . .

Nahnalaud — the Big Mountain

The Big Mountain

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)

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)

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)

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)

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.

The Six Waterfalls Hike

Because Pohnpei’s rainforested terrain is so challenging to move through, inexperienced hikers might think a jaunt into the wild interior of the island is out of reach. It isn’t. Almost anyone in relatively good physical condition can handle the “Six Waterfalls Hike”, which delves into the verdant forests and lush raparian environment of the remote Nanmeir Valley above Salapwuk.

The adventure begins near Salapwuk Elementary School. The early part of the hike follows a wide, mostly flat track through the trees. This is a good place to look for Asian waterbuffalo, or carabao, which some of the Salapwuk residents use as beasts of burden. The large, big-horned animals, which were brought to Pohnpei from the Philippines by the Spanish in the 1890s, may look fearsome, but are actually quite shy, gentle creatures. You might see one lolling about in a patch of mud or plodding along with a smiling child perched on its back.

Over time the track becomes a narrow footpath and begins to roll up and down as it passes through hilly native forests. Shortly after crossing the Sihngar Stream (Pilen Sihngar), there’s a fork in the trail. Continuing straight will keep you above and west of the river, while the eastern way leads down toward the upper Lehnmesi River and Pahnairlap, a serene punchbowl falls with a great little pool beneath it.

The rest of the hike follows along the banks of the river and occasionally crosses over it, stopping at four more waterfalls — Nikotoapw, Olotong, Iro, and Nan Emp — each with its own unique character. This segment is quite difficult, as hikers must traverse the round, jumbled stones that line the riverbed and its banks. Go slow, use your hands, and watch your footing.

Nikotoapw Waterfall is found a bit to the east of the river, above where the Nikotoapw Stream (Pilen Nikotoapw) joins the Lehnmesi. The site is screened by a pool with a wide “block falls” behind it, which hikers must circumvent. On the other side, the stream issues from a narrow slot. Continue through this and one comes to an enclosure mostly hidden from outside. There lies the falls and its sizable pool. If you swim under the falls and climb up on the rocks behind, you’ll find a cave.

The third falls, Olotong, is found on the opposite side of the Lehnmesi from Nikotoapwpw. This is followed by plenty of hiking in the riverbed and one segment where the trail leaves the river and cuts through the forest before coming back to the watercourse. Iro and Nan Emp are both found on the west side of the river not too far apart.

The sixth falls, called Lipwentiak, is also hidden from view by the topography. At one point the river narrows and passes through a high-walled slot. Though there is a way up and around, the easiest and safest way past is to swim through the slot. On the other side, the walls open up to reveal a large pool with high walls on all sides, an island of cobbles, and beyond all that, a tiered “horsetail falls” that flows from a vaguely heart-shaped portal of dark rock. It’s very dramatic.

In all, the trek offers tons of great swimming and truly unreal scenery. Good footwear is a must.

Plan for 6-8 hours round-trip with short swim breaks at each waterfall.

The Story of the Eel of Pahdol

A long time ago, a couple from Wene came to live in a place called Iro. One day there was a great storm and the heavy rains resulted in a huge flood. Two women in the area went out to fish in the flood, and while they were fishing, a starling flew over and dropped a small stone. The women took the stone home and gave it to the couple from Wene. Later, at a place called Pahnkipar (“under the pandanus tree”), the stone broke apart and from it was hatched a tiny freshwater eel. The couple kept the eel as their pet and allowed it to live in a pool at Pahdol (“under the hill”) in Pahnais. When the eel grew up, however, it began to act in sinister ways. At night, the eel would escape from its pool and sneak into the house, where it would stare at the sleeping couple. The couple became uncomfortable and decided to kill and eat the eel, but the eel overheard their plan, came into the house, and attacked them. The couple fled into the forest and hid under a huge rock, where they believed they’d be safe. The eel discovered the hiding place and ambushed the couple, devouring them alive.

The eel then traveled into the Nanmeir Valley in Pohnpei’s interior and followed the Lehnmesi River source. There she met Kiroun Meir, a high-titled man, who brought her to live with him at his home. The two became lovers and the eel was impregnated. She was restless, however, and departed, continuing to follow the river. At Lipwentiak, the eel encountered a hunter named Kiroun Mand, killing and eating eels. Recoiling at this sight, she created a sharp turn in the river with the writhing of her body. Soon after, she gave birth to her first daughter, the matriarch of the Sounlipwentiak subclan. She had other children later who became the founders of the Lasiadohng (“eels of the dohng tree”) and Lasiakotop (“eels of the kotop palm”) subclans. After that, the eel went to live in Dauen Sapwalap, where she terrorized the local inhabitants, devouring so many that the land became mostly deserted. When the monster finally died, her body formed Dolen Nett.

Lou Rahn Cave & Waterfall

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.

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.
Please visit the Local Guides & Tour Operators page for a list of experienced guides available for hikes to Lou Rahn. Offer $37-50.00 for a group of five or less.
