Location
From the Security Development Project headquarters take the sealed road south (not the road that goes back down to Chiang Klang). As this road turns north take a dirt road south. Drive past the National Park ranger station to a Y junction. Take the left hand fork, turning right at another Y junction, and drive down the rough track to where it levels out and there is a track heading downhill on the right. Take this right hand turning and follow the track, which is rough, as far as a Hmong farm at 47Q 718242 2145049. A small stream flows past the farm, but to find the path to the cave continue along the track up the slope the other side of the stream and then head left into the trees. The stream has cut a valley about 10 m deep and sinks at the end of the valley at the base of a boulder pile.
Description
From the 15 m wide by 5 m high entrance the passage descends a boulder slope for 20 m to where the cave narrows to a 2 m x 2 m hole. The way on is to climb down the flowstone and continue down the steeply descending cave. Where a canyon opens up in the floor of the passage a ladder was used to descend a 6 m drop. Below the ladder pitch the cave opens up into a chamber of 20 m wide and 15 m high. The stream joins the cave a waterfall in the roof and the rock is seen to be vertically folded at this location. From the chamber the stream goes along a passage 2 m wide and 3 m for a few metres before it drops down a 16 m inclined pitch. Below the pitch the cave continues to descend steeply for another 25 m before the passage narrows and is choked with gravel.
