Description 1



Located at the north end of Napa Hai, close to the track that runs alongside the lake. The cave entrance is just downstream of a small lake outflow that runs under the track. Entrance is a large (10m high x 5m wide) downhill passage, taking a small stream. Climb down over boulders and down through small hole at front left of entrance chamber to enter the cave proper down steep slope. This gains a stream passage, with the water occupying most of the width of the passage. It is possible to traverse on the right-hand side for 8m, until a 4m free-climbable cascade is reached. 5m beyond this is a second cascade, which can be free-climbed (but a handline is useful!) by teetering down a steep conglomerate bank on the lefthand side of the passage. 10m of easy walking passage lead to a free-climbable cascade and then a further two cascades in close succession, which can be rigged from an enormous conglomerate feature that is part of the right-hand wall. [At the bottom of the final cascade, some of the water drains away through a steep descending body-width slot at floor level. This slot has been explored feet first to neck depth, but water began to back up around the caver’s body. It may be possible safely to explore this slot by diverting the small proportion of water that usually flows through the slot along the main stream passage (using sandbags or similar), leaving the slot itself dry.] Downstream, the cave continues as easy meandering walking stream passage, gradually diminishing in height until a sump is reached after 20m. The entire cave is in conglomerate. Note: On one visit to this cave (after a period of relatively dry weather), the water had backed up to the entrance. AA, RB, DC, SFl, HG, RGe, FL, MLa, PT
