A spacious mouth 2.20 metres high by 0.80 wide will lead us into the main cave. Main, because on the right and under the same overhanging visor we find another secondary mouth. After overcoming an r+1.90 we reach this mouth of 3.50 metres high by 0.50 wide. It is an ascending gallery of about 3 metres with an r+1 and which ends 1.50 metres further on. Here we find the highest point of the cavity: +4.

We return to the main mouth and descend a ramp about 3.80 metres; here we find two levels. If we continue descending, 3 metres further we will reach some small steps that drop us into a P-13.80. If we go along the top, after overcoming an r+1 and advancing 2.60 metres we reach the upper part of the same aforementioned pit. On the other side of the pit, the gallery divides in two; the right one becomes impenetrable at 2.70 metres and the left one does the same at 2 metres. If we return to the head of the P-13.80 the gallery continues in a N direction; we will climb about 5 metres, above unstable ground where a couple of pits can be seen that connect with the main one. A couple of rotten planks would facilitate the passage for the old prospectors of archaeological remains. We continue 7.60 metres along a dusty descending ramp, and below a wedged block. The dimensions are 5.70 metres high and 0.90 wide. We pass an r-1; 5 metres further we find more wedged blocks. The left gallery ends 6 metres further on, a large block acts as a partition; the right one becomes very narrow and impenetrable (0.26 m) but a small pit can be seen and it continues with a faint air current. Above we can advance about 8 metres more to end in a closure of large blocks. Returning to the pit, we rappel 6.50 metres to a landing. In a N direction there is a descending ramp that closes after about 5 metres, but the continuation of the joint and the pit can be seen. On the ceiling we see the small pits we mentioned before and the precariousness of the blocks.

Continuing the rappel, 7 metres further down and after passing a selective narrow section, we land on a debris cone. If we go towards the S we descend about 11 metres passing under two blocks and reaching a meandering fissure, with an r-2.60 where the continuation can be seen but not the possibility of passage. Up to here the gallery was about 8 m high by 0.40 metres wide, descending to 1.20 metres high at this point. We are at -23 metres of depth.

Returning to the base of the pit, we descend about 7 metres to a small step; here we already have a selective narrow passage, we can still advance about 6 metres more to almost the head of a pit. Here we notice that a small air current comes out. We are at -26 metres. The continuation is quite obvious.

Vertical drop: 30 m. (+4/-26).
