We reach the entrance through a kind of trench, the product of the significant fracture in the ground. The entrance is of good dimensions (4×3 m); we observe remains of a dry-stone wall, which is evidence that this part of the cave has served as a fold.

At 10 metres we find on the left the entrance of a small hanging gallery, which we suppose connects with the cova Petita d'en Rubí. On the right we find an entrance of 0.6×0.5 metres that leads to a shaft of -1.8 metres that takes us to a small room of 1×1.4 metres with another small shaft of -0.9 metres with no apparent continuation.

We return to the main gallery and 4 metres further on we find some fallen blocks that we will climb over on the right; here the height of the gallery is 4 metres. We advance 7 metres more and find an r-1.7 followed by an r-3, which is descended on the left with the help of a fixed rope hanging from 2 Parabolts.

The gallery descends, and on the left there is a blind shaft of -1.5 metres. The ceiling height here is 8 metres, the width is about 2 metres. We will climb 8 metres until we find another chaos of blocks, continue 11 metres more and climb over an r+1.2 m; 4 metres further on there is a P-2.6, which through an inaccessible passage leads to the lower gallery that we will describe later. 7 metres more and we find ourselves beneath the ceiling where the bats usually form a colony. Further on we see the light of the upper entrance at 7 metres of height.

On the left side, between the wall and the blocks, a shaft of 4.7 metres communicates with the lower gallery. The main gallery bifurcates, separated by large blocks; if we go right, at 8 metres there is a small blind shaft of 1.2 metres. The width is 1 metre and the height 7.

Eight metres more and we find a small deviation on the left; it is a descending fissure of about 5 metres, not accessible because of its narrowness. We advance 10 metres more and the gallery becomes a crawlway (0.50×0.50 m); we will crawl for about 7 metres, and although the continuation is quite evident, we could not get past the narrowness.

We go back about 3 metres and observe that by climbing an E-2.2 m there seems to be an upper access, but it also becomes very narrow. At this point there are some graffiti: “M. GAS, M. BEGUER 1950, J. MONTAGUT, TORRAS, F.GAS, VIÑAS”.

Having exhausted the right branch, we go back to the start of the bifurcation and will go to the left gallery; we will climb a ramp of about 4 metres and enter a gallery 0.40 metres wide and 2 high. At 2 metres we find an r-1.9 metres, we continue 4 metres and a hole in the ceiling at +0.70 metres takes us to a small upper gallery through which we will not be able to advance because of its narrowness. Continuing below, at 2.50 metres we find a small shaft of -1.5 m; ahead, at 3 metres, the gallery narrows. If we descend the aforementioned small shaft, in direction E the gallery ends at 7 metres; if we go in direction O it ends at 9 metres in a small room.

According to what the friends of the Espeleo Club Tortosa told us, the state of the cavity is quite deplorable due to the massive visits by all kinds of people. It seems that hunts have even been organised against the bat colony with air rifles and also with stone throws.
