The entrance is 0.82x1.26 m and had to be cleared; it turns right and climbs almost 1 metre to a small chamber with a strong draught, which changes direction depending on the time of year. At this point you have to turn around to descend a narrow passage that was also cleared and follow a short gallery to a narrow shaft, also cleared, 3 metres deep. From the small chamber to the base of this shaft, a fixed rope is rigged to make the exit easier. At the base, a short 3-metre gallery leads to the head of a 7.6-metre shaft that was also cleared. Once at the base, if you head back towards the entrance you find a step up that leads to a passage with abundant lithogenic formations, followed by a small shaft that becomes impassable. Back at the base of the shaft, you descend a steep ramp of large blocks; halfway down it, towards the entrance, there is a small passage that leads to an area with abundant and curious stalagmitic formations. Back on the ramp, you finish descending to the base; at some times of year this is covered by about 10 cm of water. The continuation is in the ceiling of the gallery; a fixed rope is rigged, you have to climb up to a wooden platform installed to make access easier and climb a narrow passage that had to be cleared; the shaft is 6.4 metres high, followed by an ascending 3-metre ramp, but wider. Once at the top you are at the base of a 6.45-metre shaft that is equipped with a fixed rope; the head of the shaft is also quite narrow. Once past the shaft you find an equipped handline that leads to a gallery with plenty of formation where the ceiling rises up until it is lost from view; in this area a lot of water trickles down and the draught is also lost. At the end of the gallery it forms a narrow passage with a small pool of water on the floor; the gallery descends until it meets a shaft of about -8 metres that is equipped with a rope. The gallery climbs back up until reaching a point where the floor begins to collapse; from here a long equipped handline begins until reaching a “Y” rope rig. From this point the end of the fissure can be seen further on with no continuation, and the rope rigged in the “Y” is found, descending a -15.5-metre shaft to a pile of blocks that form a base; the fixed rope reaches this point, the excess rope is gathered here and allows descent of the next -11-metre shaft located on the W side of the fissure. The base of the shaft is on a steep downward slope and ends in a new -5.8-metre shaft. The base of this continues descending until reaching the final area with large blocks and quite broken up, with the floor full of a fine white earth resulting from decalcification. The passage is 238.9 metres with an elevation change of 48.5 metres (-45.1/+3.40).

Passage with abundant lithogenic formations. Area with abundant and curious stalagmitic formations. Gallery with plenty of formation where the ceiling rises up until it is lost from view.

The base of the ramp at some times of year is covered by about 10 cm of water. In the area of the gallery with plenty of formation a lot of water trickles down. At the end of the gallery there is a narrow passage with a small pool of water on the floor.

The cave is fully rigged for exploration, except for the last section that descends to the lowest point, for which you only need to bring a 20-metre rope and 3 hangers for “spit”. All defective ropes have been changed and a new wooden platform has been put in to access the ascending shaft. Inside the cave, in some corners, there are still pieces of unusable rope and some plastic water bottles that the first explorers used; at some point all of this should be removed.
