The entrance, difficult to find, is in a bed of sandy limestone.

Ten metres of stooping leads to 4m of tight, flat out crawling into the top of a 7m high chamber, about 15m in diameter. A climb down into the chamber reveals a bouldery left hand wall. Other rising slopes have no passage at the top and the good draught is lost. The draught could also not be found in the chamber in July 2017.
