A blowing mouth 0.60 x 0.70 m leads to an r-0.90, where there is a gallery in a Northerly direction that leads to a small P-3.70. This entrance gallery has a flat-out passage on the right, which it has not been possible to pass. Descending the 3.70 metre pit one reaches a gallery about 15 metres long and about 2 metres wide, while the height ranges from about 2.50 to 3 metres. If we head south, at 6 metres, and overcoming an r+0.70 one accesses a chamber between blocks about 2 metres in perimeter; at the end there is a small pit between blocks (0.90 x 0.40 m) through which, descending 1.60 m, one reaches a short gallery, where this sector of the cave ends. Turning back, where the r+0.70 was overcome, looking to the left a raised passage between blocks is observed where one must overcome an r+1.75, accessing an ascending gallery that is somewhat higher than the main gallery. At 1.20 metres there is on the right a small pit of -0.90 metres; 1.50 metres further on, on the left, there is a pit (-2.50 m) that leads to the main gallery. On the right there is a crawl of about 3 metres. Five metres further up, the gallery ends in a small room between blocks. Returning to the main gallery, base of the P-3.70, heading North, we leave on the left a P-3 that leads between rocks to a tiny room; at 7.80 metres it is observed that on the right there is a fissure at +0.90 m from which comes the air current that emerges from the mouth of the cavity; it is a very narrow joint (0.40 m) through which it is only possible to advance some 3 metres, because a block bars the way. Nevertheless, the continuation can be glimpsed, and moreover a sounding gives a P-3.70. This is the theoretical point of connection with a possible pit of about -17 m, which should be further up, but which for the moment it has not been possible to locate.
