Access to the cavity is via a descending mouth between blocks and which shortly communicates again with the outside in a wide rise of 2.7m.

At the S end of the rise the cavity continues through a narrow crawlway on a pronounced slope and after a change of direction, the crawlway becomes more horizontal and communicates with the horizontal chamber of the cavity.

At the N end of the chamber there is a descending flat-out passage that leads us after some rises, to the shaft of the cavity of about -6m. Some block rises allow us to descend it to the lowest point of the cavity.

To access the S zone of the chamber it can be done by 2 different passages. The first of them is the most direct, through a 32x40cm flat-out passage and the second, after slightly ascending a rise of 1.3m, which communicates with a narrow and high crevice in a SW direction that goes in a few more metres until it ends on crossing with another orthogonal joint.
