Dolen Nett / Pohnlehr

Hiking / TrekkingCave, Tunnel or BunkerWorld War II FortificationsBird-WatchingCamping

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.

Featured Routes

There are many ways to get to the top of Dolen Nett. We have covered four routes on the Greater Nett & Western U Eco-Adventure Map.

(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

Pohnpei's Short-Eared Owl (Asio flammeus)
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.

The German Road

Hiking / TrekkingArchaeological Site / RuinBird-Watching

In 1909, the German colonial government tried to force the residents of Sokehs to build a road around the northern end of Sokehs Island. When the people didn’t cooperate, they were beaten and humiliated. Ultimately, this sparked the Sokehs Rebellion, Pohnpei’s last and most famous insurrection. The German administrator Gustav Boeder was murdered near Mwalok along with a few of his men, and the rebels, under the leadership of a lesser chief titled Soumadau, then gathered strength, attacked, and besieged Kolonia. The Germans imported 400 Melanesian soldiers to hunt down the insurgents, and several German warships shelled the rebel refuge on Sokehs Mountain, forcing the rebels to flee to other sites. Within a few months, all of the rebels had either surrendered or been captured. The leaders of the rebellion were executed at a spot near the northernmost tip of Kolonia (called Kumwunlaid) and the people of Sokehs were exiled by force to mining camps in Palau and Yap, their lands given to immigrants from Pohnpei and Chuuk’s outer islands.

Mangrove blossom, Pohnpei, Federated States of Micronesia (FSM)
Portions of the “road” (which is actually a stone foot-path) can still be seen, winding through the mangroves not far from the current road. The longest and most accessible segment begins opposite the Nan Imwinsapw Park and runs east for 0.26 km (0.16 mi). One of the best times to do the walk is during high tide, when the mangrove trees are reflected in the still waters of the swamp forest. The German Road is one of the few registered historical sites in the State.

Nan Imwinsapw en Epwel

Nan Imwinsapw is a name that is found in several places around Pohnpei, roughly translating as “cape” or “point” and more literally “in the tip of the land.” In the case of Sokehs Island, the area is significant because of the presence of a large number of prehistoric stone ruins at the foot of the mountain and because of an association with important myths, including the story of a Yapese magician named Sou Iap (not to be confused with Soupaip, the ancient name of Sokehs Island and also Sokehs Rock). Nan Imwinsapw en Epwel is also said to be the only location in all of Sokehs Island where coconut crabs can be found. A small, ill-conceived park / picnic area near the coast commemorates the spot.

Sokehs Rock

Hiking / TrekkingCave, Tunnel or BunkerSport ClimbingBird-WatchingCampingPicnicking

Paipalap, or Sokehs Rock, is without question the most striking feature of Pohnpei’s topography. Over 100 vertical meters (328 ft) of exposed basalt form the upper portion of a gigantic volcanic plug that juts from the north end of Sokehs Mountain and looms over Pohnpei’s harbor and only town, Kolonia. An unmarked trail leading to the Rock, “The Spire”, and “The Adam’s Apple” begins south of a brown house 1.2 km (0.74 mi) beyond Mwalok A-1 Store and just before the Danipei Church (ask permission before hiking). The steep path is well-defined with steep cement steps near the bottom and then a level segment with two
large basalt outcroppings and some cave-like formations. Three quarters of the way along, it begins to follow an electrical conduit running to the beacon on the summit (202 m / 663 ft).

A hiker ascends Sokehs Rock, Pohnpei, Federated States of Micronesia (FSM)

Though not a technical climb, the ascent of the Rock itself is sketchy (triple-pitch, 5.6 R unassisted) and should only be attempted on clear, dry days, as the rocks are treacherous when wet. Pitch 1 begins at the
“Tree Cliff”
and skirts a 70° face with the assistance of tree roots, fixed ropes (these you can trust), and the electrical conduit. This section is often underestimated and may, in fact, be the most dangerous part of the endeavor. Several people have been injured in falls at this spot. Pitch 2 starts at the rear foot of the main rock and involves a steep climb with some assistance from the conduit. The crux is a 2-meter section where the conduit has corroded and is no help at all. Climbers must rely on natural holds and a narrow crevice. Ropes also hang along the conduit, but do not trust your weight to any of them as they are in various states of deterioration. Pitch 3 is easier, though no less exposed. Most people straddle the conduit and haul themselves up.

Once on level ground, you can pick out the path that winds through scattered patches of wild pineapples, ferns, and a grove of trees that makes an ideal
campsite
before ending at the main cliff on the northern end of the Rock. Spectacular views of the lagoon, reef passes, tuna fleets, and northern islands are found at several spots along the cliff face. On clear days, Pakin Atoll is visible to the west, and you may get a glimpse of Pohnpei’s shy — and perhaps threatened — short-eared owl (Asio flammeus).

The Creation of Sokehs Rock

An ancient Pohnpeian legend states that long ago a man traveling near what is now Sokehs Island was overwhelmed by the force of a geyser-like spring which burst up and swept him all the way to a distant island. There he acquired the help of a powerful magician, who conjured a huge stone and plugged up the spring. Ever after, the rock was known as Paipalap, “the great paip (boulder).” In another version of the story, a Yapese sorcerer named Sou Iap was disturbed by the sound of rushing water and voyaged to Pohnpei to investigate. Upon discovering a great fountain on Sokehs Island, Sou Iap blocked the opening with piles of sea sponges.

Trad Climbing on the Face

Sokehs Rock face, Pohnpei, Federated States of Micronesia (FSM)
The north face of Sokehs Rock has considerable trad climbing potential, though it has yet to be fully explored (several climbers have rappelled down and raved about what they saw there). It is, however, quite extreme and under-cut in places. Note that a top-rope would need to be no less than 200 meters (666 ft) in length. Pioneers are welcome!

The Japanese Road on Sokehs Mountain (Pohndollap), Pohnpei, Federated States of Micronesia (FSM)

Sokehs Mountain or Pohndollap, which means “on the big hill,” is a long, mostly flat-topped ridge running north-south along the length of Sokehs Island with a knoll-like summit near the middle. The mountain was a refuge for the insurgents of the Sokehs Rebellion and later a key location in the Japanese defense of Pohnpei during World War II. The mountain’s attractions are mostly war-related, though it is also a highly-regarded birding spot.

The hike begins at the end of the paving above the Sokehs Municipal Office and climbs steadily along the rocky Japanese Road (or you can drive to the halfway point). At the top of the mountain, the road turns north next to a terrace on which the Japanese barracks structures originally stood — now the site of a concrete nahs built by the Office of Tourism in the late-2000s. From this point, it’s roughly 0.23 km (0.14 mi) south to the Coastal Battery and 0.78 km (0.48 mi) north to the summit of Dollap (276 m / 906 ft).

Japanese-Era Historical Sites

Command Post & Anti-Aircraft Battery

This site is centered around the Japanese Command Post, from which military operations on the Ridge were directed. There are many structures in the area:

Defensive Trench — This narrow, rock-lined trench has been partially swallowed by a bamboo grove that must have established itself after the war. The trench makes two 90 degree turns around something that is now buried beneath the roots of a massive tree. It’s unclear what the structure was, but electrical cables can still seen coming out of it through the trench wall.

Stone Look-Out — This elevated observation point is found just above the west wall of the Command Post, reached by several concrete steps. From the circular roof-less enclosure at the top, you can look out over Gun #1 and the Command Post foundations.

Personnel Tunnel / Shelter — This L-shaped personnel tunnel is found opposite Gun #1 under what looks like a man-made hill. The tunnel runs southeast and then makes a 90-degree turn before terminating. It’s about 7 meters long in total. The structure was probably intended as a bomb shelter.

Anti-Aircraft Guns — The two guns in the battery are identical: Type 89 12.7 cm twin double-purpose guns, which could pivot 360 degrees on their mounts and also tilt to fire at enemy aircraft overhead. Both guns are surrounded by sloped concrete revetments about 2 meters high with recessed ammunition magazines around the ring (some of which still have large machine springs in them). It took roughly one year for sixteen Pohnpeian laborers to move the guns to the Ridge and install them in their current positions. Gun #1 faces northeast, while Gun #2 points north and is missing its shield. An uncovered shaft lies just to the rear of each of the guns and drops 2 meters into the ground, connecting to a tunnel that housed the gun’s power cables. These shafts are potential hazards, especially when the grass is high. Take special care when walking around the sites to avoid falling into either of the holes!

Command Post Foundations — Only the concrete basement foundations of the Command Post structure exist today. It seems to have been divided into two rooms. There’s a strange tower-like structure at the north side that TTPI archaeologist Duane Denfeld believed was used for target-bearing. The entrance is on the south side. To the left of the entrance under some trees is a flight of concrete stairs that has tipped partially on its side. It probably led up to the Look-Out and was either damaged by a bomb blast or undermined by erosion.

Machine Gun Pillbox — North of Gun #2 is a large pillbox with similar architecture as the coastal battery bunker. A set of stairs leads down to a stone corridor, which turns left into a circular chamber with slit openings on the front. From the outside, the structure is nearly invisible. The pillbox was probably intended for a machine gun, or more than one. As the chamber stays quite dry even during heavy rain, it’s a nice place to camp.

Mysterious Concrete Shaft — Southwest of the pillbox is a circular concrete shaft with a steel rung ladder leading downward. The shaft is currently flooded and its purpose is unclear. We’re still looking for information about this intriguing feature.

Barracks Area

The foundations of barracks, a kitchen, and mess hall are found at the north end of the Coastal Battery trail. The largest concentration of foundations is east of the path, indicating at least three large buildings. Concrete steps are found east of the Coastal Battery trail and south of the main road. A large water tank on a rock platform next to the path probably supplied the kitchen area. An identical tank to the east may have been for a washroom. Foundations extend all the way to the Tourism nahs. A slightly-sloped retaining wall built in the Japanese stone masonry style, called uchikomihagi, (unshaped, fitted stones) frames the terrace on which the foundations lie, running east-west along the main road and then turning south. There’s also an unknown foundation isolated from the others north of the main road with earthen revetments on all sides. It might have been a magazine for heavy ordnance, though the design is different from facilities on Lenger and Sapwtik.

Coastal Battery

The Coastal Battery is found at the end of a well-defined trail 0.23 km (0.14 mi) southwest of the cinderblock nahs. There are several notable features:

Coastal Gun & Bunker — A 15 cm naval gun is found in a large rock and steel bunker on the western slope of the mountain. The gun was manufactured by the British company Armstrong-Whitworth in 1905 and remains in good condition. It was intended to protect against surface incursions from Palikir Pass, a primary barrier reef passage to the west, but it may not have seen much action. The gun had a range of about 7 kilometers (4.3 mi). The bunker is roughly 8 meters by 6 meters with steel I-beams supporting the concrete ceiling and the dirt that is mounded over it. It would have been difficult to identify the feature from the air. There are two ammunition magazines behind the gun with heavy steel doors. A short corridor connects the rear of the bunker with a prominent trench which runs south for roughly 60 meters (196 ft), ending at a large bomb crater.

A stone trench and rifle pit on Sokehs Mountain (Pohndollap), Pohnpei, Federated States of Micronesia (FSM)

Rifle Pit — Twenty-five meters (82 ft) east of the gun bunker is a P-shaped rifle pit with rock walls. It may have originally been connected to the trench system mentioned above.

South Point

From the top of the Coastal Battery bunker, a trail runs 0.37 km (0.23 mi) south to the end of the Ridge. Along the way it passes scattered foundations, small water tanks, and several stone rifle pits. Little is known about the structures in this area. Bomb craters are obvious in many places. The path terminates at the mountain’s southernmost point–a narrow fin with steep slopes on both sides.

Rifle Pits on Western Slope

West of the Summit Road, 0.28 km (0.17 mi) north of the Command Post, is a complex of small stone rifle pits. Four rifle pits were investigated (two on either side of the path), with the pair to the south being the most extensive. Undoubtedly, there are many structures of this variety around the mountain’s slopes that have yet to be discovered. The area is lower than its surroundings and tends to be very muddy.

Power Station

Immediately east of the Summit Road, just before it begins to climb to the peak, are the remains of a Japanese power station. The most prominent features are a Yanmar 60 KVA generator and three concrete tanks–two for water that cooled the engines and one for fuel. Though the power station building is no more, the steel roof trusses still lie across the ground.

Summit Area

FSM Telecom has claimed the summit of Dollap, and the steel Japanese searchlight platform (about 5 meters in diameter) now supports one of two cellular phone towers. The views from the top of one of the accessible Telecom structures are spectacular and unobstructed. Just below the knoll is an L-shaped defensive trench with rock walls, probably for the men who manned the light. Above this is a small Japanese monument.
