Standing at the entrance, inside it we find that it divides into two narrow passages; the left one, once past the narrow passage, places us at the base of a shaft of about 3 metres that opens to the outside, while the gallery continues about 3 metres forming a kind of chamber. At the base of the shaft, on the right, we find a narrow passage that connects with the gallery coming from the entrance on its right side.

A few metres further on we find a junction; an ascending step of 0.9 m and another descending one of the same measurements place us in two galleries at different levels that finally coincide through a very narrow passage. Following the descending gallery, after 1.5 metres we reach a junction; on the right the gallery becomes high and forms a couple of chambers, with a couple of small branches without continuation. Back at the junction, on the left we follow a narrow gallery that in its upper part connects with the upper gallery mentioned above. Following the gallery we reach a chamber with a height of more than 3 metres; through the lower part of this chamber a new passage leads us to a new fork; in the upper part we find a passage of 2.34 metres, and in the lower part another passage of about 3 metres long by two metres wide with a low ceiling; both passages connect at their final part.

In the cavity we find abundant formation, although there is also quite a lot of it damaged.
