The cavity has two entrances. The upper entrance is a short crawl that leads into a pit of 8 metres, which connects with a pit of about 35 metres deep with a width of up to 5x8 metres. Through the lower entrance we find a first drop of 3 metres, followed by another of 7 metres; the base of this latter pit communicates laterally with a small chamber, the base of which is slightly lower; from this base a pit of 14 metres opens, ending in a cul-de-sac. At the start of this pit there is a crawl that communicates with the large main pit, and in its middle it also has a narrow communication with the same pit. The base of the main pit is located at -46 metres, forming a large ledge of 5x5 metres. At this point several openings begin; the smallest is 0.75 m. The main pit, on one side, ends at 10 metres, while on the other we descend 6 metres to a ledge where through a window we access the aforementioned large pit. From the window one can see on the other side and about 4 metres lower another window. Once the main pit is descended we are at the level of -95 metres; the cavity continues with more modest dimensions: first a pit of 8 metres, followed by another of 17 metres; from here we climb about 4 metres among blocks to access a window that leads into another pit, as well as a dome. At the head of the Via ERE we find a descending traverse followed by a pit of 4 metres that leads to a chamber where the floor is formed by very unstable blocks; at this point a pit of 30 metres begins, at the base of 4x2 metres. Shortly before finishing the descent of the 30-metre pit we find a window that gives access to the Via GERS. Once past the connection, halfway down this pit we find a horizontal gallery, at the end of which and by means of a narrow crawl we access the last pit of 9 metres.

The upper entrance is a short crawl that leads into a pit of 8 metres. Accessing through the lower entrance, a first drop of 3 metres and another of 7 metres. The base of the main pit is located at -46 metres, which is accessed by means of a small pendulum. If we access through the smallest entrance (0.75 m), this gives way to a direct vertical of -52 metres. From the window one can access another window by performing a traverse, which is located at the head of the Via ERE. Located again at the head of the Via ERE, we find a descending traverse followed by a pit of 4 metres. The Via GERS is formed by a series of small pits and narrow passages that end up linking with the main route. The drop of the five known surveys has a maximum difference between them of 10 metres: the ERE-CEC gives it -125 m, the ECG -129, the SIE-CEA -130, the GES-CMB -134 and the GERS-AEM -135 metres; the difference is basically from -95 metres onwards, since up to this level all the measurements are quite similar.
