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.

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.
