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.

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.
  • 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.

Southwest Side

Descending a ladder into a subterranean oil tank on Lenger Island, Pohnpei, Federated States of Micronesia (FSM)

Subterranean Crude Oil Facility (Pahnlenger)

Built beneath Dolen Lenger, the Japanese crude oil storage complex is without question the most impressive of the island’s historical sites. If tight spaces, heights, cobwebs, bats, or the dark make you nervous, this is where you should grab your flashlight and confront your phobias! You don’t want to miss this experience, but do take care where you put your feet and watch out for swiftlets darting about.

The facility is accessed through the first of a trio of steel gates that opens onto a wide rock tunnel lying parallel to the hillside (Gates 2 & 3 are blocked by mud and rock-fall). Steel ladders in alcoves opposite each of the gates run up the wall to concrete lofts from which Japanese personnel could inspect the massive oil tanks. Each tank is 40 meters long and 10 meters wide (131 x 33 ft) with an arched, riveted ceiling and an estimated capacity of 3,300 metric tons. From each loft a second ladder descends 10 meters (33 ft) through a hatch to the floor of the tank. Depending on recent rains, there may between 10 cm and a meter of standing water on the floor, but it’s usually possible to explore without getting too wet. Japanese graffiti on the wall of the first loft reads: “Push forward bravely and strive.” Records seem to indicate that only the third tank was operational. A large diesel engine in front of Tank 3 was probably used to pump the oil in and out. A pipe runs all the way to the coast.

One of four caves dynamited out by the Japanese on Lenger Island, Pohnpei, Federated States of Micronesia (FSM)

Storage Caves (Pahnaiau)

The four caves carved into the slope of Dolen Lenger were probably intended for use as storage facilities (and also for defense as a last resort), but may not have been completed. Cave 1 is tiny (about 6 meters deep). The other three are grouped together 50 meters (164 ft) to the northwest. Cave 2 is 15 meters deep, 8.5 meters across (49 x 28 ft), and nearly as high with a wide entrance sloping steeply to a soggy floor. If you venture down, be careful of broken glass from bottles that might have been meant for Molotov cocktails (gasoline bombs). Cave 3 is slightly larger and deeper with several terraces. A line of rock-filled barrels at the mouth seems to have been added as protection against a land attack, and the third terrace may have been intended for a machine gun. Cave 4 is the largest with a depth of 28 meters. All of the caves are muddy, often have standing water on their floors, and are occupied by colonies of Caroline Islands swiftlets. The name of the area, Pahnaiau, means “under the banyan tree.”

Concrete Plant Equipment (Pahnaiau)

West of the main path to the caves is a ballast mound with a mango tree on top and a cluster of equipment used in the process of making cement: three concrete mixers, a large Yanmar diesel engine, and the 610 mm gauge rail lines that were used to transport dynamited rock from the cave sites along the hillside. A rock-crusher lies 23 meters (75 feet) southwest of the mixers.

South Side

Oil Tank Complex (Pahnkamal)

This large walled complex originally contained two steel tanks for the storage of crude oil, which was pumped in from the coast. The larger tank, with a 1000-liter capacity, was dismantled in the 1970s by a man who needed steel plates for his ship. He was in the process of taking apart the smaller one, when the government intervened. The existing tank can be entered where the lower panels have been removed. The roof is accessible via a ladder on the inside, leading to a manhole. A courtyard wall surrounds the entire facility (now being used by local residents as a pigpen) and concrete channels lead to a pair of rectangular cisterns (currently piled with coconut husks). Large bomb craters from the American bombardment are found on the northwest and south sides.

The gate and tunnel leading to an underground aviation fuel tank on Lenger Island, Pohnpei, Federated States of Micronesia (FSM)

Aviation Fuel Reservoir Tunnel (Pahnkamal)

Northwest of the main path is a subterranean tank that supplied the seaplanes with aviation fuel. A steel door in the hillside opens on a tunnel about 8 meters long (typically flooded with about 20 cm of standing water and silty mud). At the end of the tunnel, the fuel pipes turn to the right and disappear into a concrete wall, behind which the reservoir lies. A ladder runs up to a secondary entrance hatch on the slope, but it is now rusted shut. The Japanese took fuel from this location by truck to the seaplane facility.

East Side

Cisterns & Machines(Nanpeilam)

Footpaths leading toward residences on the eastern coast pass a variety of rusting machine parts and two rectangular concrete cisterns. The southernmost cistern can be entered through a hole knocked in the south wall. A ladder also runs up to the roof.

The Banyan Wheel, a Japanese machine completely absorbed by a banyan on Lenger Island, Pohnpei, Federated States of Micronesia (FSM)

“The Banyan Wheel” (Dausong)

The most photogenic of the island’s attractions is not far from the main path on a terrace cut into the eastern slope of Dolen Lenger. There are several concrete foundations here and on one of them is an unidentified machine (perhaps an engine or rock-crusher) that has been completely absorbed by a huge banyan tree, such that the large machine wheel is permanently fixed on the outside of the tree with two roots growing right through the spokes. Take our word for it: it’s pretty darn cool.

Northeast Side

Seaplane Hangar & Aircraft Wreckage (Dietakai)

The hangar on the northeast side of the island once housed the “flying boats” that flew between Chuuk, Pohnpei, and the Marshall Islands and the Naval Type-O Observation seaplanes that were used for recon. Roof girders of a partially collapsed Japanese seaplane hangar on Lenger Island, Pohnpei, Federated States of Micronesia (FSM)The structure sustained at least two direct hits from bombs, leaving massive craters at the front and on the southeast wall and possibly contributing to the eventual collapse of most of the braced girder roof in the 1980s (only the rear portion still stands). Near the northeast corner is a half-buried air compressor and just beyond this the engine cylinder of a destroyed aircraft, but the tangled girders make it difficult to move further inside from this direction. A careful search near the east side of the foundation should yield the wreckage of at least one plane (an Aichi E13A1 Jake), including the engine and propeller, portions of a wing, a pontoon, strut, and bits of bulkhead next to one of the carriers used to move the planes. The hangar can be much more easily entered at the rear, where the roof girders are still intact. A pair of carriers — on their way to being devoured by a ficus — were used to transport the seaplanes.

Seaplane Ramp & Apron (Dietakai)

The large seaplane ramp and apron dates to 1939 or shortly after and was constructed by a labor force consisting of Japanese, Korean, Pingelapese, Mwoakillese, and Pohnpeian workers. The structure lies on a reclaimed portion of the island and stretches northeast into the sea. The underwater section was made from concrete slabs poured elsewhere and lowered from barges, where they were assembled by divers. Stone seawalls around the perimeter were constructed in the highly stable yabane-tanizumi configuration. Written accounts left by local workers describe slave-labor conditions and harsh punishments for anyone who did not cooperate (one account says men were strung up to bake in the sun). A Pohnpeian marching dance (“Ke Dehr Lemeleme Me Se Ruksang Doadoahk en Kaigun”) composed during the event, commemorates the regular desertions of laborers.

Today, the cratered apron has been claimed by the forest and is difficult to even identify from the ground, but at the time of writing there was a clear path across it. The ramp was repaired by the Americans and used as the primary airstrip until the current airport on Dekehtik was completed. It remains mostly intact, though several structures in the area post-date the Japanese period (including an old hut for picnickers and the concrete tanks from a giant clam hatchery that operated in the 1990s).

Dolen Lenger

Japanese beer bottle, Pohnpei, Federated States of Micronesia (FSM)

Dug-Outs & Tunnels (Dolen Lenger)

The ascent of Dolen Lenger follows the northernmost of two Japanese roads that lead up the hill and eventually intersect. The lower part of the southern road is mostly blocked by trees and mud and is no longer a good way to access the hill, but you can explore the upper section, where several dug-outs cut into the slope on either side. Two of the entrances are connected by a short tunnel.

Gatepost & Barracks Foundations (Dolen Lenger)

A bit further up the northern path, hikers pass a gatepost (its twin has fallen down the hill), adorned with round, colorful river stones imported from Japan. Naval personnel gathered at this spot for their morning meeting. Not far ahead, the foundations of a barracks complex are found on a large terrace in the hillside. The area is littered with Japanese beer bottles, old diesel engines, steel water tanks, and rusting machine parts. A short tunnel worms into the slope to the left of where the path climbs a flight of concrete steps and continues up the hill.

The drum of a 110 cm Japanese searchlight on Lenger Island, Pohnpei, Federated States of Micronesia (FSM)

Searchlight (Dolen Lenger)

The drum and turn-table of a 110 cm searchlight (probably a Navy Model 92) lie just off the right edge of the path. The light was originally mounted on the rock outcropping five meters (16 ft) west of the its current position and was used to identify targets at night. It was probably dismantled by American personnel after the war.

Small Gun Station (Dolen Lenger)

Further along, a deviation from the main path leads to an unknown battery, probably for a machine gun or small artillery, which was removed after the war. A short stone wall protects the site and contains two ammunition magazines.

Anti-Aircraft Gun Stations (Dolen Lenger)

Two anti-aircraft batteries crown the hill, one to the west and the other at the end of the main path. Both sites consist of concrete rings surrounded by stone and earth revetments and a number of ammunition magazines (nine at the first station and six at the second). Naval 8 cm Type 3 Dual-Purpose Guns were installed at these locations to protect the seaplane base and other important Lenger facilities. Unfortunately, both guns were removed after the war.

Dolen Lenger Summit Area

From the last anti-aircraft gun station, it’s possible to continue another 50 meters (164 ft) or so to the 77 meter summit of the hill (marked with a brass USGS benchmark) and pick your way to the cliff-top for expansive views of Kolonia and the northern lagoon. Bring a machete and take care at the edge of the precipice.

Coastal Battery & 15 cm Naval Gun (Dolen Lenger)

Just north of the searchlight, a branch in the path turns west and descends a series of muddy steps to the coastal batteries and their four naval gun stations. Records disagree as to whether guns were actually installed at all four of the stations or if one station at each battery was a decoy. The only gun remaining on Lenger — a 15 cm 40 caliber British Armstrong-Whitworth naval canon — lies on its side in the mud at the southernmost station not far from the pedestal mount. It was probably thrown there by the detonation of one of the many bombs dropped by Allied aircraft in 1944. The barrel and shield are separated from the jacket and recuperator and partly buried. Japanese records state that the 15 cm gun on Sokehs Mountain was originally installed at Lenger and moved during the war. Lenger’s guns were intended to prevent surface invasions from Pweitik Passage to the northwest and had a range of roughly 7 kilometers (4.3 mi).

Heavy Ordnance Magazine Foundation (Dolen Lenger)

Past the gun stations is the foundation of what was probably a magazine for heavy ordnance surrounded by impressive inclined blast walls of quarried basalt rock. As is true of the best examples of Japanese architecture on Pohnpei, the stones were laid in the alternating diagonal pattern called “herringbone style” (or yabane-tanizumi). The site was most definitely covered during the operational period and camouflaged to make it invisible from the air.

West Side

Coastal Barracks Foundations

The remains of two large barracks are found on the western coast of the island. Both of the structures were wooden pitched-roof buildings raised above the ground on concrete posts and reached by short flights of stairs. Each barracks housed as many as fifty men. Only the posts and stairs remain today. The southern foundation has a nahs built on top of it, which was part of one the island’s two “resorts” in the 1990s.

ACKNOWLEDGMENTS

The Lenger Island guide would not exist without the amazing work and cooperation of archaeologist Takuya Nagaoka, who was the first person to map the historical sites on Lenger. Nagaoka’s meticulous survey maps and exhaustive report (as yet, unpublished) were indispensable in the process of finding and interpreting neglected sites that had become heavily overgrown.
