The cave resides in a doline on the down valley side of the track. (The GPS grid reference above possibly not correct). The entrance is a very muddy 11m climb which is best laddered. A small chamber chokes with calcite and the way on is a muddy hole where the ladder ends. This is a slide down a muddy tube into a 3.5m wide passage. Ahead, on the left, a calcited ramp rises to a choke. The main passage continues down a 2m drop and the sandy-floored passage continues until it lowers and ends in a small chamber 1m high by 0.5m wide.
Eleven metres back from the end on the right is a body-sized hole leading to a tube and a squeeze under calcite at the bottom into a chamber. The roof here is covered in helictites, "antlers" and other fine formations.
A short climb around a block on the right soon chokes. A hole in the floor leads to a steep rift and at the base is a muddy dig where an echo could initially be heard until mud became too liquid. This was excavated on one occasion over Easter 2009 and it is probably worth a further dig in a spell of very dry weather.
