The entrance presents itself in the form of a doline, with a descending gallery that reaches a chamber of considerable dimensions. The floor continues sloping down to the middle of the chamber, where it begins to rise until it becomes obstructed. Right at the deepest part of the chamber and entering to the right there is a narrow gallery that is obstructed by stones and gravel. On the left side of the gallery through which we accessed the chamber there is another ascending gallery that heads in the opposite direction from the entrance, and then descends in an E. direction to a very narrow fissure that leads to another gallery where we reach the maximum depth and which returns to the chamber from which we had set out.
