Dolen Nahnsapwe, “hill of thunder,” is a small peak near the Nett–U 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.

The northernmost section of Madolenihmw is separated from the rest of the municipality by a range of low mountains that run east-west from Mesihsou to Alohkapw. This range was fortified by the Japanese army during World War II because it was easily accessible and commanded excellent views of lands both to the north and the south. The hills are riddled with tunnels and man-made caves, and a ridge path runs from the east end and connects with the primary mountain system in the central part of the island. There was a time when Japanese soldiers could travel from Mesihsou all the way to Kupwuriso without ever leaving the mountains. Small 75-80 mm guns were also installed at hidden spots among the hills.
There are many potential hikes one could do in these interesting mountains, but we’ve chosen to focus on three routes leading to small peaks along the ridge: Timwen Men, Dolakapw, and Pohn Tehnmei. All three cross private land.
Timwen Men
The name of this small peak at the western end of the ridge means “beak of the bird,” a reference to the many brown noddies that can be seen flying around the summit. The hike begins at the houses near the end of the road, belonging to the extended family of Eiber Rosario, and passes through the family’s sakau plantation on the slope. Any semblance of a trail vanishes at the foot of the hill, where you have to clamber up the steep, muddy hillside. At the top, there’s an extensive network of Japanese defensive trenches. The Japanese ridge path goes east as far as Mesihsou and west to Kupwuriso, but the problem with hiking the entire distance in one go is that the mountain range is broken up into a number of private parcels owned by different (and sometimes competing) families. The trail is easy to follow as it goes west toward the Timwen Men summit (331 m / 1,086 ft). Along the way, you’ll pass several impressive tunnels that bore into the hill and connect with the trench system. Two circular pits seem to have been either small caliber gun stations (possibly 80 mm) or rifle positions. No guns are found there now. The summit is a little overgrown, but still affords nice views of the valley.
The hike takes about 3 hours round-trip.
To arrange for a guide, ask for the colorful Eiber Rosario at the houses near the end of the road. You may also be able to locate Eiber by calling his son-in-law, Colton, at +691.923.6941. Offer $20.
Dolakapw (Edienleng)
This hike starts at the main road opposite a small store, passes through a group of houses, and follows a well-traveled footpath, climbing steadily but never steeply to Dolakapw (“new hill”), a peak in Edienleng. The trail ends at a plantation of sakau and other agroforestry crops. From there the route curves around the south side of the hill (with views of the Sapwalap plain), where two large Japanese tunnels burrow into the slope. The lower one is partially collapsed, the steel rails for a mining car still jutting out of the hole. The roof here is unstable, so it would be unwise to venture inside. The tunnel is about 15 meters long. The second tunnel, a little higher up the hill, is in better shape with U-shaped steel supports holding up the rocky roof. Bats and Caroline Islands swiftlets nest at the rear. The landowner believes that the Japanese intended to connect the two tunnels, but abandoned the project once the Allied bombing campaign began. The semi-open Dolakapw summit (305 m / 1,001 ft) is just above.
The hike takes about 3 hours round-trip.
To find a guide, visit the small store on the coastal side of the road and ask for Isaac Fred. Offer $20.
Pohn Tehnmei
This short, strenuous hike begins at the home of brothers Atsent and Romeo Welcher at the end of an intermittently paved road west of Nan Pailong. There isn’t much of a trail; the route just goes straight up the slope behind the house along an eroded track used to drag huge sakau pounding stones, called peitehl, down from the mountaintop. The first thing encountered at the top is the quarry site itself — a collection of pits from which the stones have been dug. There was a time when people came from all over the island to get peitehl at this spot. Currently, the state forbids the practice, but you may get the distinct impression that it’s still going on nonetheless. Not far from the top of the hill, a gigantic peitehl marks the spot where the brothers Olsihpa and Olsohpa looked down and first laid eyes on Sounahleng, the place where they would eventually begin the building of Nan Madol (there’s no view from here now, unfortunately). Also, a trio of large stones slightly to the west are said to have been formed from the bodies of a man, his wife, and their child. From there you can continue west along the ridge to the Pohn Tehnmei summit (347 m / 1,138 ft). The tree cover on the ridge, however, obscures any good views of the lowlands.
Plan for about 2 to 3 hours round-trip for this adventure.
Japanese Tunnel
At the base of the hill on the Welcher farmstead is a 14 meter-long curving Japanese tunnel. Mining car rails lie along the floor, and though the mouth of the cave is partially collapsed, the rest is supported by U-shaped steel supports. You can enter carefully and walk to the end (bring a headlamp or flashlight and expect some bats).
Either Atsent or Romeo Welcher (+691.925.8075) can be hired as guides, though Romeo’s English is better. If you can’t get them by phone, just go to the house and ask one of them to take you up. Offer $20.
Kupwuriso, Pohnpei’s fifth highest mountain (depending on how you count them), is impossible to miss when driving through eastern U, where it towers over everything, its precipitous slopes clad in groves of endemic palms called kotop (Clinostigma ponapensis). When the Pohnpeian hero Isokelekel sailed around the island in the mid-1600s on a mission to overthrow the Saudeleur dynasty, he initially balked at the sight of the mountain palms which he mistook for an army of giant warriors dressed in grass skirts. It was not until he returned to And Atoll, that a local woman pointed out his mistake. Giants or no, the mountain has an ominous look and feel. It’s unusually close to the coast and rises up very steeply, making it appear much taller than it really is (630 m / 2,067 ft). The name means “stomach.”
Awak Valley Approach
There are two major routes to the small, rocky summit (630 m). The first begins not far from the end of the primary paved road at the rear of the Awak Valley. To protect Mwahnd and Alohkapw (Areu) Passages from invasion, the Japanese decided to place two 15 cm naval canons just below the summit of Kupwuriso at a place called Dol Reirei (“long hill”). To get the massive weapons up the mountain, they constructed a road that climbs up on the south side of the Awak Valley and follows the ridge north. The hike uses this track for most of the way, starting on a rocky private footpath to the right of the road. The steepest section comes at the beginning. Once on the ridge, things mostly flatten out, though there are some gentle ups and downs. The terrain is fairly tame the rest of the way, passing through upland groves of kotop palm, wild banana plants (utin wel), and gnarled stands of campnosperma (dohng) and elaeocarpus (sadak) — trees used to make canoe hulls.
One of the benefits of climbing Kupwuriso is that you’re more likely to get a clear view from the summit than from Nahnalaud. The perspective is better, too; Nahnalaud’s summit sits on a wide plateau, while Kupwuriso’s looks down to the valley from the top of a cliff. Sometimes, however, the mountain is fog-bound — especially from about noon to 2 PM. Plan for 4-6 hours round-trip.
Rohi Approach
The second route starts in Rohi district at the end of a paved road. This way is shorter but considerably more strenuous, shooting 1.3 km (0.82 mi) straight up the side of the mountain. It should be noted that a number of hikers have sustained injuries on this approach, so hire a good guide, go slow, and watch for loose rocks! The route begins in the inhabited lowland agroforest, which Pohnpeians call nansapw, and quickly ascends to the mid-level forests (nanwel), populated by giant hardwoods and tree-ferns. Beyond, the forest opens up and kotop palms abound. Once the slope starts to even out, you’ve entered the cloud forest — a fantasy world of stunted, twisting trees and air plants. It’s always wet here, and every surface is covered with a thick layer of bryophytic growth. Plan for 4-6 hours round-trip.
Japanese Gun Battery
The two guns are the British Armstrong Whitworth naval type identical to the one on Sokehs Mountain. Both are housed in steel and concrete bunkers and separated by a pillbox, where machine guns were placed. The battery was installed in 1943 and took fifty-five local men eight months to complete. At 580 meters (1,903 ft), these are the highest guns on Pohnpei Island. The gnarled forest that has grown up in front of the gun sites is mesmerizing, especially in foggy conditions.
Bird-Watching
Birders will find much to look at on the way up the mountain. Besides the typical honey-eaters, starlings, and lorikeets, this is a good place to look for the Crimson-Crowned Fruit Dove, Imperial Pigeon, and Pohnpei Cicadabird. Swiftlets are common at the summit.
Please visit the Birding page for additional information.
Ridge Camping
There’s a fantastic place to camp at 593 meters not far from the gun sites with a beautiful, unobstructed view of the valley. Bring your own water, dry tender, a tarp or heavy-duty rainfly, and stakes for your tent and tarp (high winds are a distinct possibility at such elevations). Remember to leave your site exactly as you found it. Pack out everything you packed in and properly bury all human waste.
Hiring a Local Guide
A lot of people know the way up Kupwuriso, so finding a guide is not difficult. If you want to tackle the Rohi approach, Miller Benjamin (from Saladak) is a good choice. From Awak, we recommend Relio Lengsi. Conservation Society of Pohnpei (CSP) can also assist you in finding a guide. Offer $40-50 for a group of five hikers or less (plus tips). Agree on a price beforehand.
Awak Pah Marine Park is the most well-known of the parks in the area and has a nice big sign right out on the main road. From the parking area near the owner’s house, a 0.2 km (0.12 mi) coral and concrete walkway leads to the water through a dense section of mangrove forests. At the end, there’s a tiny picnic area by the water, a large nahs, and a few other huts that can be rented at an extra cost. The water is shallow and a bit silty on the south side and deep on the west and northwest side where a huge pair of PVC rings have been anchored (a good place to swim). The rock wall by the water is a fun place to jump from, but it can be difficult to climb back out. Snorkeling can be pretty good to the west along the reef wall with lots of small fish and some interesting coral growth. Unfortunately, local visitors have been careless with their garbage and the beautiful reef scenery is frequently ruined by the presence of discarded aluminum soda cans or flashlight batteries — a sad trend on Pohnpei. Water clarity varies from crystal clear to murky depending on the tides; it’s best to visit on an in-coming tide. You can visit Awak Marine Park without making arrangements beforehand.
Paieke Marine Park
Owned by Bryan Damarlane, this pleasant, breezy swim-picnic-camp park is located on a network of dredged coral causeways that extend out into the lagoon at the point where the road begins to turn east toward the Awak valley. A number of thatched residential huts varying in size and a nahs (meeting hut) or two are positioned around the water’s edge for guests at an extra cost. The swimming is good all along the west side, though the shallows tend to be silty rather than sandy. Snorkelers should follow the edge of the reef further out into the lagoon for best results. The kids will love tinkering around in the shallows under the shady trees. Paieke operates on a reservation-only basis.
To make reservations for day visits or overnight stays, call Bryan Damarlane at +691.925.0382.
Pein Ahi Marine Park
This charming, but little-known, park (pictured at top) is found just after Awak Marine Park, but as it lacks a sign, most people drive right by without realizing it’s there. From the road, a beautiful 0.16 km (0.1 mi) stone and coral walkway winds through the picturesque mangrove forests and ends at a grassy picnic area with a nahs and a large fish pond. The family keeps some very curious pufferfish and a few other reef fish in the pond, mostly for the amusement of visiting local children. The swimming all around the outside of the pond walls is excellent with consistently good water clarity. There’s a relatively shallow area on the south side that works well for kids or beginning swimmers and deeper water on the west and north. They also have a pair of large bamboo-pontoon rafts that are fun to cruise around the mangrove fringe on. Except on big holidays, you can usually visit without making any prior arrangements.
Nihco Marine Park
Nihco Marine Park, on the southwest coast of scenic Sokehs Bay is an appealing place for people of all ages to swim, barbecue, and soak up the sun. The park is comprised of a narrow, man-made semi-circle of sand with a placid lagoon in the middle where turtles and reef fish are kept. There’s a white-sand beach on the outer edge and simple thatched huts for either day or overnight visits. Small kayaks can be rented for a few dollars. The place can be packed on weekends and holidays.
To make reservations for day visits or overnight stays, call +691.320.2135 / 2659.
Nihco Surf
Nihco Surf is one of two thriving operations that cater to foreign surfers and tap into the radical power of the now world-famous reef-break at Palikir Pass. The locally owned and managed camp, situated inside Nihco Marine Park, offers six air-conditioned wifi-equipped bungalows that look out over Sokehs Bay; an on-site restaurant; kayak-rental; boat tours; And Atoll trips; and daily excursions to P-Pass, Lighthouse Break, and Mwahnd Pass.
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.
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 (“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.
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.

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.
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.

The easiest waterfalls to visit on Pohnpei (no hiking required) are the tiered “horse-tail” falls, Liduhduhniap, just a few kilometers from Kolonia. When the Greater Nett Eco-Adventure Guide was published in 2015, we wrote of Liduduhniap:
“Some might consider accessibility to be a red flag and assume that a location so close to town would be completely spoiled by a constant flow of visitors and thoughtless development. That’s not the case here.”
Unfortunately, things have changed recently (2017). Under the direction of Pohnpei’s new tourism department, the landowners at Liduduhniap have chosen to severely undermine the natural integrity of the site by replacing the dirt path to the lower falls with an unsightly series of concrete steps and a concrete hut near the edge of the pool. Toilets have also been built on the site. For those of us who knew the place before this “development”, it will never be quite the same again, but Liduduhniap is still a beautiful spot — not just the two waterfalls themselves, but the greater area, which is lush, rugged, and often partially enshrouded in thick mists that drift down from the steep mountains. The population around the site is relatively sparse, and it is hoped that most of the land will remain as it has for decades — green and wild.
The Liduduhniap Waterfalls lie on a portion of the Nanipil River (Pillapen Nanipil) located right at the feet of the mountains and fed by a great deal of rain (the primary dam and reservoir that supplies the town with water is just a bit upstream). The upper falls cascades 4 meters (13 ft) into a deep basalt plunge pool with a jaw-dropping elevated view of the river valley and the slopes of the mountains. From there it spills over the lip and plummets another 8 meters or so (26 ft) into a larger, but shallower pool. Swimming is excellent at both pools, though the first is more difficult to get in and out of. Most people simply opt to take a flying leap off the rocks, but you can also carefully cross the river above the falls and climb down to the pool from the far side without too much trouble (go barefoot or wear five-fingers to avoid losing your flip-flops in the swampy sections). The water is crystal clear — except immediately after heavy rains — and always on the chilly side, making it a great escape for oppressively hot and humid Pohnpei days. The deep, narrow valley funnels air along so that there’s always a bit of a breeze, too, which keeps the ferns waving hypnotically and the temps down. No one is quite sure how deep the upper pool is, but it’s deep — deeper than you’ll ever sink after a jump. However, one must still take care to scan the water before leaping; flash floods sometimes wash tree trunks and other debris down from the mountains and these can become wedged in the pool below the surface. Depending on how high the river is, you may be able to swim up and get behind the falls, where there’s a small depression in the rock. There’s also a large cavern on the eastern side of the pool. The lower pool is too shallow for jumping.
The well-manicured and landscaped gravel trail to the site begins left of a large nahs (community hut) near the unpaved road and opposite the landowners’ house, meandering past blossoming hibiscus shrubs, plumeria trees, and ginger until it reaches a couple of ramshackle huts above the river. These make nice spots for a picnic lunch, while in the evenings the family uses them for pounding and drinking Pohnpei’s dizzying ceremonial drink, sakau (kava). Turn right by the huts and scramble down to the river to visit the upper falls. Note the mortar holes on the north side of the pool rim, where sakau was pounded in ancient times. To reach the lower pool and waterfall, continue along the main trail and down a series of concrete steps. The family charges an access fee of $1.00 per person to visit the falls. Occasionally they may ask you for $5.00 if it looks like you plan to take a lot of photos of the site.
Be advised that there have been many injuries and several fatalities at Liduduhniap! The spot is extremely prone to flash floods. In 1999, two Pohnpeians were swept away by a flash flood and carried over both falls to their deaths. In 2002, three visiting Palauan athletes were also killed by a flash flood; there’s a monument to them next to the trailhead. Danger from slips and falls is another issue. In 2012, an American educational volunteer fell to her death from the upper falls, which prompted the landowners to install a dodgy rope ladder on one side of the upper pool. Read the Safety Considerations in the right column and BE CAREFUL.
Plan for 30 min – 2 hours to enjoy the waterfalls.
Upper Nanipil Bird Walk
If you continue up the road from Liduduhniap, you’ll soon pass the dam and reservoir on the left. Just beyond this, also on the left, a footpath leads into the forest and runs through the woods above the stream for 1.1 km (0.68 mi). Among birders, this scenic walk is second only to Sokehs Mountain in terms of the variety and prevalence of species that can be seen. It’s easy to get to and doesn’t require any huffing and puffing, and the forests are rich and unspoiled and full of birds. There are no houses along the trail, which means that traffic and noise are at a minimum. You can see many species on the walk, but highlights include the Pohnpei Cicadabird (Coracina insperata), Pohnpei Fantail (Rhipidura kubaryi), Pohnpei Flycatcher (Myiagra pluto), and Crimson-Crowned Fruit Dove (Ptilinopus porphyraceus). We suggest you hire a local birding guide and bring a pair of binoculars. Stick to the path to avoid damaging this pristine watershed.
Plan for 2-3 hours for this walk.

Sengnaip Waterfall
This little-known two-tiered waterfall is located about 400 m (0.25 mi) south of the Nanipil Bird Walk described above. If you cut off the path and continue down the slope for about 170 m (186 yd), you’ll hit the main stream, which you can follow up for another 144 m (157 yd). At this point, you reach a large basalt pool that narrows on the far side and disappears into a rocky slot. You can get a great view and wonderful pictures of the falls from the rocks on the east side of the pool, but there’s no easy way to go further without swimming. If you do the latter, you’ll end up in a small plunge pool enclosed on three sides by high rock walls. There’s a cave just above the water level on the east side. The spot is unbelievably peaceful and has been seen by very few people. Treat it with utmost respect.
Like Liduduhniap downstream, this location has extreme flash flood potential. Read the Safety Considerations in the right column.
If you hire a knowledgeable guide and continue hiking south at the conclusion of the Nanipil Bird Walk (where the trail crosses a stream on a large log), you’ll soon strike the main river again. The route stays with the watercourse for 1.5 km (0.93 mi) with very gentle elevation gain (4% slope avg). At the end of this segment, the river is joined by another stream coming from the southeast. Following either course for about a third of a kilometer will lead you to a waterfall. The western route continues 0.37 km (0.23 mi) up a slope, where the hike steepens to about a 25% slope average before coming to Likei Waterfall. The eastern course leads 0.23 km (0.14 mi) with a 18% slope average to Pahn Pwet Waterfall. The two waterfalls are quite dramatic and little-known both by visitors and by local people. This area, called Nan Madap, is actually disputed territory; both Sokehs and Kitti claim it, though the municipal boundaries as they are typically drawn seem to place the location within Sokehs.
Also with a local guide, a third falls can be accessed from a completely different route, beginning just west of the community hut by the Liduduhniap trailhead. This hike climbs up the mountain slopes fairly steadily for 3 km (1.86 mi). The first two thirds of the distance is relatively easy with a slope average of about 12%, but then the slope steepens considerably to about 41%. Nan Kiepw Waterfall is high up at about 500 meters of elevation (it may be one of the highest falls on the island), just below the summit of Dolen Nanikep and off the east side of the trail. Sometimes you can see this falls from the lagoon after heavy rain.
Serious trekkers have the option of continuing past the waterfall, up to Dolen Kiepw (610 m), and on to Dolmweir (735 m), where a thatched shelter was built for hikers in 2013 (note that the roof of the hut was already deteriorating when we visited only six months or so after it was constructed). This is an admittedly tough hike with slopes ranging from 25% to 40% and very rough terrain. The shelter is 1.5 km (0.93 mi) beyond Nan Kiepw falls. From the shelter, trails run west to Pekenuht (705 m) and down into Pehleng or east to Nahnalaud (772 m).
This is by far the most popular swimming spot on the Nanipil River located 4 km (2.5 mi) from downtown Kolonia, where the watercourse turns sharply away from the Nanipil River Road and forms two deep, placid pools. There used to be a cable footbridge that crossed this portion of the stream, but now all that remains are a couple rusting cables strung high above the water. The water at the site is clean and quite cool — an excellent place to freshen up on a sweltering afternoon. Avoid the site, however, during or immediately after heavy rain, as the water gets muddy from all the sediment washing into the valley upstream. Cars can be parked on the opposite side of the road.
This is a favorite with young kids in the area, located 5.3 km (3.3 mi) from downtown Kolonia. A short walk from the Nanipil River Road leads to a long, deep pool with a steep slope on the far bank. Rope swings are often strung up on both sides of the pool, and there are some grassy spots to picnic and a tiny hut or two. The landowners, who live in a house on the side of the road opposite the trailhead, charge visitors $1.00 per person.
Flash floods are an issue at both sites, due to Nanipil Valley’s narrowness and the volume of rain that can fall in a short period of time in the steep mountains to the rear. Be wary.
Dolen Nett (“hill of Nett”) is a steep-sided mountain running the length of the Nett Point peninsula. Leaf-shaped, this peninsula juts north into the lagoon east of Kolonia and is said, in myth, to have been formed by the corpse of the same monster eel that founded the Lasialap clan, created Lipwentiak, and lived in the Lehdau River for many years. When the creature finally died, her carcass became Dolen Nett.
Like Sokehs Mountain, Dolen Nett is mostly flat on top, as if the peak was sliced off. From town, this plateau — known as Pohn Dolen Nett (“on the hill of Nett“) — looks like a manicured lawn, which has inspired the mistaken belief that it was once used as an airfield by the Japanese. In truth, there were only three Japanese airstrips on Pohnpei: one at Nanpohnmal, one in Palikir that never became fully operational, and the seaplane base on Lenger Island. There are hardwood forests around the edges of the plateau, but the central landscape of Pohn Dolen Nett is nearly treeless. Most of this open terrain consists of very resistant, and in many places, shoulder-high paddle grass and Dicranopteris ferns with swampy mires and sections of jagged basalt scattered throughout. It should be noted that the aforementioned ferns can be brutal on bare legs if you’re forcing your way through them for any length of time. That’s cat o’ nine tails brutal. Flay the flesh right off your shinbones brutal. We learned the hard way once, while mapping the location. One humble suggestion: hike in pants. Heat-stroke, too, can be an issue on the hill; with so little tree-cover, sunny days are blistering.
Japanese World War II Sites
As is true of all the high points around Pohnpei’s coasts, the Japanese fortified Dolen Nett in the late 1930s, anticipating an eventual attack by Allied forces (which came in the form of intense bombing raids rather than the expected surface-based assault). The most interesting war features are grouped together at the southern end near the true summit (an area called Pohnlehr) and include some steel drums, the barrel of a disassembled 75 mm canon lying in the woods, rock walls, two stone machine gun pillboxes, and a concrete and steel bunker that houses a second 75 mm gun in situ. To access the latter, which has excellent views of the bay between Nett and Awak, you have to move along a precipice, often partially or completely obscured by high grass. Let your guide go first to clear a path — unless you want to find yourself plummeting through empty space. The bunker itself can be entered, but it’s a bit of a grubby venture as the roof has partially collapsed and is now supported by the breech of the gun itself.
The other major site on the south side is a mobile radar array that sits on a low stone platform in the woods about 126 meters (138 yd) northwest of the gun bunker. The radar was mounted on a rotating turret in the center of a truck chassis (still intact) and the operator turned a wheel to position it. There are some large depressions in the surrounding forests that may be bomb craters, but none of the major features on the hill appear to have sustained direct damage from the bombing runs. More likely, these posts were simply abandoned, as they would not have been very effective against an aerial attack.
The woods pick up again on the north end of the mountain, and here, also, are some Japanese military features, including a large network of narrow defensive trenches, a few stone rifle pits, and machine gun emplacements.
(1) The most practical route starts behind a house next to the road in Weipowe 1.2 km (0.75 mi) south of the Nett Point turn-off. Just ask at the houses on the inland side of the road for guides. The trail is well-maintained as far as the family’s private sakau (kava) and yam plantations on the slope. The steepest bit of the climb is at the beginning — 0.4 km / 0.26 mi, 33% slope avg. Near the top of the ridge, the trail passes the entrance to a long Japanese tunnel, well worth exploring — but bring a headlamp. From there, it continues up the forested slope and eventually comes to the open fern meadows, called nanmal (0.4 km / 0.3 mi, 22% slope avg).
(2) Another trail begins 0.6 km (0.37 mi) south of Trailhead 1 (look for a narrow concrete driveway next to a giant mango tree). This may have been the primary Japanese trail, but it is now difficult to follow above the point where farmers plant their sakau. About 0.56 km (0.35 mi) along (26% slope avg), the trail collides with an impassable basalt wall over which a thin waterfall can form after heavy rain. Here the trail turns south and continues about 0.29 km (0.18 mi) with a 17% slope avg, running parallel to the wall until it ends. Then it begins to climb again, briefly emerges in a small meadow, passes through some light forest, and emerges again at a rare grove of coconut palms (185 m / 202 yd).
(3) A third route begins at the edge of the road in Paliais 0.7 km (0.43 mi) north of the Dausokele Bridge. The route is about 0.7 km (0.43 mi) to the top with a 26% slope avg.
(4) The fourth route starts on the edge of the road 1 km (0.62 mi) south of the Nett Point turn-off. It climbs fairly straight 0.27 km (0.17 mi) with an 18% slope avg up to the ridge, which is much lower here. It then turns south and follows the ridge 0.43 km (0.27 mi) until it connects with Route 1 at the Japanese tunnel entrance.
Pohnpei Short-Eared Owl
The lonely meadows and forests on the mountaintop are prime habitat for Pohnpei’s shy short-eared owl, Asio flammeus. This species has been pushed up to the mountainsides by building projects — such as the State Hospital — which destroyed its native grasslands habitat. Late afternoon is a good time to look for the large bird rising from its hidden abode as it sweeps out to hunt (we spotted it on three out of five trips).
Camping
There are many fine places to camp on Dolen Nett. The nanmal is excellent on clear nights, where you can gaze both on the star field above and the twinkling lights of Kolonia below. If you want more cover or perhaps some trees to tie a tarp or hammock to, try the forests at the southern end. Bring plenty of water — none is found on the mountaintop — and take everything you brought with you when you leave. A good campsite is one that leaves no trace.
Plan for 6-8 hours for this hike, if you want to see all the WWII features.
Please visit the Local Guides & Tour Operators page for a list of experienced guides available for hikes to Dolen Nett. Offer $37-50.00 for a group of five or less.
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.
