Paddling Lenger & Sapwtik

SwimmingSnorkelingKayaking / CanoeingMarine Reserve

As the closest lagoon islands to Kolonia and with the highest concentration of WWII historical sites anywhere around Pohnpei, Lenger and nearby Sapwtik make fantastic destinations for paddling enthusiasts. In addition to the attractions on each of the two islands, there are mangrove forests and some interesting reef environments to explore.

Around Lenger

Pahnaiau Getaway (Barbosa’s Wharf) to the Seaplane Ramp

This portion of the route is characterized by Lenger’s shallow fringe reef, a sandy, silty expanse dominated by small-scale coral growth, brilliant blue starfish, cowries, sea cucumbers of various types, and scattered beds of seagrass, which Pohnpeian’s call oaloahd. Keep an eye out for the main attraction: stingrays. They generally rest on the bottom in the sand and will shoot off when you approach. Not far beyond the wharf is the Jaluit Cistern, one of the oldest historical sites in Pohnpei State. The cistern was probably constructed in the late 1880s by German traders operating on the coast. A stone wharf originally connected it with the coast, but a few scattered stones are all that are left. Bullet holes in the masonry were caused by Allied strafing during WWII.

If you decide to make a wider arc around the island, you’ll pass over areas where the reef shelf ends and the deep part of the lagoon begins. Small sea turtles are seen on rare occasions near the reef wall. The majority of the reef fish will also be found at this natural boundary. Note, however, that the reef stretches all the way to Sapwtik in the northwest and there is no way around Lenger’s northern end without crossing it. The depth over the shelf varies from a few centimeters to a meter, depending on the time of day and the precise location. Because fragile corals and other organisms are harmed by feet or dragging keels, the northern passage should be attempted at high tide only.

The Seaplane Ramp to the Mangrove Passage

The reef on the eastern side of the island tends to be deeper than in the northwest and has denser beds of seagrass. Larger fish are found in this area, and sometimes juvenile black-tip reef sharks can be seen swishing their way around.

The Mangrove Passage to Barbosa’s Wharf

The tunnel-like mangrove passage winds about a third of a kilometer through a dense section of forest that mostly comprises members of the Rhizophora genus, identified by the arching prop roots that extend out of the water toward the tree trunks. It’s a nice, scenic paddle and a good place to spot shorebirds like the Pacific Reef Heron and Micronesian Kingfisher. Once out of the forest, you can follow the coastline past the ruins of the Japanese-era Kohatsu Wharf and back to Barbosa’s Wharf.

Around Sapwtik

A relatively well-preserved Japanese wharf extends southwest from Sapwtik’s coast all the way to the edge of the reef. This is a wonderful place for a picnic and swim or snorkel. There’s one large tree on the wharf, offering shade. To the west is a maze of mangrove clumps that are fun to paddle through (though they are not as extensive as Lenger’s) before reaching the western terminus of the island. North of the point is an exposed rocky place that’s a perfect pull-out spot for a snack. A little beyond that is the site of the coastal battery and nearby munitions magazine. Conditions north of Sapwtik’s coastline are very similar to Lenger’s northern sector — shallow and characterized by seagrass beds and silt. You shouldn’t try to kayak here except at mid to high tides. All along the coast, you’ll find evidence of Japanese occupation, low walls, foxholes, rifle pits, etc.

Sapwtik Island

Sapwtik, which means “small land,” is a tiny volcanic island located directly north of Kolonia and 0.5 km northwest of Lenger. Seen in profile, the island resembles a large submarine, leading some locals to nickname it “Submarine Island.” Sapwtik is jointly-owned by the Eschiet family, which has some small houses at the eastern end of island, and their in-laws, the Adams family. During the 1880s, Sapwtik was purchased by Jan Stanisław Kubary, a Polish naturalist and ethnographer, along with a large piece of land east of what is now Kolonia — a place called Mpwoampw. In 1896, after returning from an extended absence and finding his homestead in ruins and his claims on the properties questioned by the Spanish authorities, Kubary committed suicide. Mpwoampw and Sapwtik were then purchased by Dominique Escheit, a Belgian trader who had operated in the Marshall Islands before coming to Pohnpei. Between 1914 and 1945, the Japanese were in charge and a great deal of land was seized by the military for defensive purposes — including Sapwtik. Like its neighbor, Lenger, Sapwtik was fortified in the late 1930s in preparation for an Allied invasion that never came. The primary features are found on the low hilltop and at the western terminus.

Sapwtik Island Attractions

Japanese Wharf

Visitors to Sapwtik will want to make their first stop at the Japanese Wharf, a 296 meter-long (324 yd) basalt structure that juts out from the island’s southwest coast all the way to the edge of the reef. With the exception of the very end, which has sustained some damage from waves, the wharf is in excellent condition almost 80 years after it was built — a testament to the quality of Japanese construction during the colonial period (and the use of the highly stable tanizumi, or herringbone, style of stonework). The wharf connects with the coastal road, also built by the Japanese, which skirts the mangroves from one end of the island to the other. The road is built above a stone retaining wall that stabilizes it against the swampy mangrove environment. Retaining walls also run along the opposite edge to prevent erosion from the steep hillside above.

Snorkeling & Swimming

All the ocean areas around Sapwtik belong to the Sapwtik Marine Protected Area, a sanctuary protected by legislation. The snorkeling off the reef walls at the end of the wharf is quite nice with generally good visibility and lots of fish. Just start at the wharf and follow the reef wall in either direction (the further from the island, the better it gets). The best place to swim is also right off the end of the wharf. Shallow areas on either sides of the wharf are silty.

Command Center & Barracks

The central hill is most easily accessed from the maintained Japanese coastal road. About 60 meters east of the wharf, hikers can cut off the road and up the slope (another 60 m) to reach the summit. The Adam’s family keeps the hill extremely tidy, cutting the grass, planting flowers, and keeping the historical features free of vines and brush. The place has a manicured, park-like feel and a stunning view of everything to the south. One of the best preserved yabane-tanizumi style rock walls on Pohnpei runs the length of the hilltop on the south side with two breaks, where earthen ramps lead up to the top. Two foundations were likely a command center and a barracks for personnel stationed on the island. The northern foundation is the largest and has seven sets of steps leading up to where the floor once was. The structure itself would have been wooden, while only the support posts and the lower parts of the walls were concrete. Two large concrete cisterns are connected to the two foundations (check out the bullet holes from Allied strafing). At the north end of the complex, the hill road begins, cutting right through the hill and running all the way to the gun batteries at the northwestern end of the island. Some of the road is currently impassable due to piles of felled trees and branches, but it’s impressive none the less.

To visit the gun batteries, it’s best to return to the coastal road and hike northwest all the way to the end. The road is well-kept and easy to follow.

Magazine Complex / Shell Storage

From the cut-off point for the hilltop, it’s about 150 m (164 yd) along the road to the first point of interest, a high-walled magazine complex for heavy ordnance similar to the one at the coastal gun battery on Lenger. The surrounding basalt rock wall (also tanizumi style) runs north and then curves sharply back to the south to enclose the foundation of the magazine structure, which is about 6 meters long. On the inside of the enclosure, the walls are steeply sloped. There is no roof, but the entire feature may have been covered with canvas and camouflaged during war-time. The entrance is narrow — less than 2 meters wide — and curved.

Coastal Gun Battery

About 12 meters northwest of the magazine is the first of four 75 mm field gun stations. These are similar to the structures on Lenger, though the Sapwtik sites are more primitive with less concrete and more earthen features. No guns remain, and two of the sites may have been decoys that never had guns installed. Guns would have protected the primary entrance to Kolonia at Pweitik Passage (Kepidauen Pweitik) to the northwest. A footpath continues north past the gun emplacements and then turns southeast to follow the contour of the hill. Along this are a few stone rifle pits or machine gun emplacements. Old Japanese beer bottles litter the forest.

NOTE: The ruins of a searchlight and a tunnel, cutting completely through part of the central hill, also exist on Sapwtik, but we did not have the opportunity to locate them during our brief period of fieldwork on the island. If you’re interested in seeing these features, contact Richie Adams at (+691.320.5735). The Pacific Wrecks website has photos of both.

Coordinates

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

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

Coordinates

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

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

Sokehs Island GPS Data

Downloadable GPS Data Files

The following files contain all the packaged GPS data for each of the featured locations in Sokehs Island.

Three file types are provided. KMZ and KML files are compatible with Google Earth. KML is compatible with Google Maps. GPX files can be imported into ArcGIS (a professional mapping application) and some hand-held GPS devices.

NOTE: All files are free to the public and can be used for any purpose without permission.

Google Earth imagery exhibits some scaling errors in this sector (i.e. the GPS track, which was checked multiple times with multiple devices, does not line up with the imagery for the primary road leading up Sokehs Mountain). We are confident that our data is as accurate as possible and that some of the aerial images on Google Earth are incorrectly positioned.

Sokehs Island (2013) – All destinations and landmarks

Coordinates

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

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

Dauen Sapwalap / Senipehn Mangrove Reserve

Dauen Sapwalap is the largest drainage in Madolenihmw, a wide, meandering channel that cuts through the mangrove forests from Kitamw and eventually empties into Madolenihmw Bay. Although the Lehdau River (Pillapen Lehdau) is probably the largest contributor to this major estuary, the two are not synonymous; the channel is also fed by three other watercourses, including the Kitamw Stream (Pilen Kitamw), Pwadapwad Stream (Pilen Pwadapwad), and River of Sekere Riau (Pillapen Sekere Riau). According to legend, a powerful demi-god named Lapongo — the same character involved in the story of Takaiuh peak — dug out the channel with his penis. The matriarch of the Lasialap Clan — a great eel responsible for the creation of Lipwentiak in Kitti and whose tail formed the great mountain in Nett, Pohnlehr — was also said to have dwelt in this channel for many years, terrorizing the local inhabitants.

During the 1889-1890 wars between the Spanish and Pohnpeians, which began in Ohwa and concluded in Kitamw, two contingents of Spanish troops were dispatched at the mouth of Dauen Sapwalap and attempted to move up both banks of the Pillapen Lehdau (Lehdau River) to reach a small half-finished fort built on a low hill by the Pohnpeian fighters. The first group of soldiers got terribly lost in the tangled forests and happened upon the fort only by mere chance. The second group was forced off-route by a seemingly supernatural flood and also ended up lost, camping overnight at Elieliwi before joining the fray. The assault cost the Spanish 21 men, and in the end the Pohnpeians merely withdrew and yielded a position that had meant little to them from the beginning.

In the last decade, the estuary became part of the Senipehn Mangrove Forest Reserve and afforded some environmental protections; tree-cutting, fishing, and gathering of other natural resources in the area is prohibited in most circumstances. Paddlers can explore the 2.6 km (1.62 mi) primary channel and its side passages by launching near the Lehdau River bridge, at the end of the road near Tahio, at the Madolenihmw “Ice Dock”, or at the MERIP boathouse.

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

Takaiuh peak, Madolenihmw, Pohnpei Island, Federated States of Micronesia (FSM)

Takaiuh Peak

While Sokehs Rock is the stand-out natural feature in the north, in Madolenihmw that title certainly goes to Takaiuh (“standing rock”), a majestic conical hill-island on the north side of the bay. Westerners called this feature “Sugarloaf” after the molded cones of sugar that were popular in Western Europe as early as 1470, but the local name and its story are much more interesting (see Madolenihmw Bay Area page for more).

Paddlers can get right up close to the iconic hill for a view from the water that is better than from anywhere on land. There’s also good fun to be had noodling around in the mangrove forests on the eastern shore (at high tide). A sweet spot to stop for a picnic lunch is the top of an exposed rocky rise 0.36 km (0.22 mi) northwest of the peak (no mangroves skirt this bit of the shore).

Pahn Dieinuh

Pahn Dieinuh, the southern point of the Dolopwail peninsula, is significant historically for the 1836 conflict that began there between the visiting British whaleship Falcon and two rival Pohnpeian chiefs — Luhk en Kesik ( the Nahnmwarki) and the Wasai, the first and second ranking men in the royal line, respectively. Things got ugly when the Nahnmwarki made a move to seize the ship and its cargo. When the ship attempted to flee, it ran up on the reef. The cargo was transferred to Nahpali Island and then stolen a month later by the Nahnmwarki‘s brother, Nahnawa. A battle ensued on Nahpali between Nahnawa‘s party and the whalers, ending in the deaths of the ship’s captain and three other sailors. The Wasai, who had been challenging the Nahnmwarki‘s authority for some time, seized this opportunity to rid the land of his enemy by joining the crews of other whaleships in hunting down both Nahnawa and the Nahnmwarki. Fighting continued for several days until the Nahnmwarki was shot and Nahnawa captured and hanged from the yardarm of the whaleship Lambton. Both bodies were buried at Pahn Dieinuh, and the Wasai assumed the position of the Nahnmwarki. There isn’t much of anything to see at Pahn Dieinuh now, but it’s a good spot for a break mid-route. The closest launch points are MERIP boathouse, the “Ice Dock”, and the Metipw launch.

Mwudokolos Island

In addition to the seven islands (Nahpali, Dekemwahu, Na, Dehketik, Nahkapw, Nahnningi, and Mall) found around Temwen, there are three small islands to the north that shouldn’t be missed. The first of these — Mwudokolos — is found a half-kilometer (0.33 mi) northeast of Metipw and easily accessed from the coral-dredged causeway/dock found there (ask at the nearest house for permission to launch). Archaeologist Arthur Saxe believed that the island was tied to Nan Madol in some way and that it might even be a man-made island, but Japanese archaeologists working on the island in recent years have found no hard evidence to support that idea. They did discover prehistoric stone structures and a house platform that dates to the Nahnmwarki Period of Nan Madol (post-1700). Glass beads, sherds, and clay pipes were also found, suggesting that Mwudokolos was occupied by foreign traders in the late 1800s. The island is privately owned, but unoccupied.

  • To obtain permission for day visits or overnight stays, call Sesuko Hadley at +691.320.2540.

Dahu Reirei Island, Pohnpei, Federated States of Micronesia (FSM)

Dahu Reirei Island

From Mwudokolos, paddlers can continue 1.8 km (1.13 mi) further north through the easternmost of two dredged reef channels to reach Dahu Reirei (“long channel”), a narrow, man-made islet with huts for picnickers and campers and lots of pleasant swimming and snorkeling. When we say this island is narrow, we mean narrow (10 meters wide). Unless you like being crammed together elbow-to-elbow, avoid the place on weekends and holidays. It’s also not a place to be on intensely hot days (there are no trees large enough to provide shade) or during bad weather (the island is hardly a meter above sea level at high tide). On partly-cloudy weekdays, however, it can be heavenly. The surrounding water is generally crystal-clear and the reefs, which consist mainly of varieties of staghorn coral, are surprisingly healthy and relatively well-populated with reef fish. Small thatched huts along the length of the strip can be rented for the day or overnight.

  • To make reservations for day visits or overnight stays and to arrange boat transport, call Joseph Helgenberger at +691.320.2229.

Lepin Dau (“Channel Island”)

The final island covered in this sector (it’s just off the edge of the Central Madolenihmw map, but appears on the U & Northern Madolenihmw map) is claimed by the same family as Dahu Reirei and has no official name, but as it lies adjacent to the primary channel every boat in the area uses to go from Areu and Ohwa to Madolenihmw Bay, it’s known as Lepin Dau or “Channel Island.” This island is larger and higher than Dahu Reirei and has some welcoming tree-cover (mostly pandanus). The channel on the west side is a nice spot to snorkel at slack tide, but at other times, the current can be so strong that snorkelers and swimmers run a strong risk of being swept away. A better spot for snorkeling is in the blue holes around the southeast side — well out of the path of the current. Here you can find beautiful coral grottoes, huge schools of needlefish, barracuda, cuttlefish, trumpetfish, angelfish, and parrotfish, an odd seasnake (the latter are venomous, but so passive that they pose little danger to snorkelers), and from time to time even eagle rays and small green turtles. It’s a fantastic picnic destination for paddlers.

  • You don’t really need to get permission to make day visits to “Channel Island,” but overnighters should call Joseph Helgenberger at +691.320.2229.

Nanwap Marine Protected Area

The reefs on the north side of Kepidauen Deleur make up the Nanwap Marine Protected Area (MPA), a marine reserve with excellent snorkeling and diving. The best place to snorkel is about 1.3 km east of Metipw in a protected reef hole, but watch for strong currents.

Mwudokolos is found a half-kilometer (0.33 mi) northeast of Metipw and easily accessed from the coral-dredged causeway/dock found there (ask at the nearest house for permission to launch if you’re paddling out). The privately owned, but uninhabited, island has prehistoric stone structures that date to the Nahnmwarki Period of Nan Madol (post-1700).
