It has an entrance about 15 metres wide, and even has a secondary lateral access under a small rocky cornice on its western side. One enters on an almost straight heading of 190º, advancing between walls that first narrow and then remain for a good stretch with a width of 3 to 6 metres, until reaching almost the end of the cave, where it narrows again to form a conduit one metre wide and 10 metres long, which above already has an emerged part half a metre high, and which finally opens into the main air chamber of large dimensions, about 20 metres on its longest side and up to 6 metres high to the ceiling.

The floor of the cave rises slowly from the entrance, located at -14 metres, until reaching the air chamber where the floor is at -2 metres, even allowing one to stand in some places.
