The mouth is formed by a large fissure. From the N side of this and next to the path we descend a first shaft of 3.25 metres that places us on a floor about 3 metres long, the point where a shaft of a little more than 8 metres deep opens. Once at the base and in a NE direction the gallery descends in a ramp with a couple of drops, the first of which requires rigging, reaching the maximum depth of 23.8 metres.

Located again at the base of the shaft, if we continue in a S direction we will soon climb a small drop, entering a gallery with abundant stalactites; before reaching the end of the gallery on the right-hand side we find a narrow shaft about 3 metres deep that does not require equipment to descend. Once at the base we enter a chamber where on the left we find a small shaft of about 2 metres that leads to a diaclase that ends up becoming impenetrable. If we continue straight on the gallery climbs a little until reaching a point where we find an intersection of diaclases, both becoming impenetrable within a few metres. As for the height of the diaclase it cannot be measured, but given the existing air current it is very likely that it leads to the exterior.
