The entrance, small (1 m x 0.5 m) and inclined, first opens onto a narrow step down, followed by a very short sloping passage that leads into the joint where the shaft opens. Initially not very wide (0.7 m x 1.2 m), this shaft widens up to a first ledge immediately followed by a second, more comfortable one. Below lies the widest part of the cavity, a lateral flow of calcite widening the whole shaft to comfortable dimensions (4 m x 5 m). The arrival is onto a large elongated ledge that leads to the edge of a second shaft (2 m x 4 m) about fifteen metres deep, with two entrances. At the bottom, a small series of small steps leads to a third shaft (1.5 m x 4 m) ending in a pinched joint with a little clay. In the last shaft there are a few possibilities of continuation, subject to digging work.
