Location
This cave is on the north-west flank of Doi Tham Makaeng. The old Japanese road joins the H1095 1 km south of the viewpoint at 47Q 410500 2161400, at the top of a 10 m bank beside the new road. Follow the track south for about 1 km to where there are two small dolines. The cave is at the bottom of the slightly smaller, 30 m deep, doline.
Description
This is a big, steeply descending cave that goes down over boulders at a 45¦ angle. At the start the passage is 20 m wide and 5 m high until a 10 m pitch is reached. This can be bypassed by climbing down through boulders a few metres back from the top of the pitch. Below the pitch the passage continues over breakdown to where it becomes a twisting canyon 1 m wide and 15 m high. Several short climbs and cascades need to be descended. Exploration stopped due to bad air with the passage seen to continue. The cave is estimated to be 150 m deep in an area with a depth potential of 500 m.
