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.
