It is a group of small conduits hanging on the crag, except for the one at ground level. These conduits have no communication between them; the sum of all of them is 95 metres of passage and 26.5 metres of height, but the reality is that the most important conduit only has 33 metres of passage and a drop of +7.5 metres. The development of the conduits ranges between 10-17 metres, except for the one of greatest height on the crag, which presents a passage of 33 metres parallel to the crag. This hole opens at +19 metres from the ground and is accessed by an artificial path built on the wall; after covering 33 metres it emerges again on the crag at +26.5 metres of height. To the left of the entrance of the previous conduit, we find hanging on the crag the access to another conduit of about 18 metres of passage.

The cave that is at ground level has a passage of 14 metres and ends in a flooded area. The other two mouths are in the parking area, one almost above the other at 4 and 6 metres from the ground, and have 17 and 13 metres of passage respectively.
