The 3 x 1 metre entrance gives way to a gallery on a ramp where, a few metres from the entrance, a fairly narrow gallery 7 metres long with an inclined section crosses it; past this we find a 1 metre step, then we continue a few metres until we find a gallery on one side; we leave this one and continue along the previous one, which from this point begins to climb until we reach a fork produced by a large 'topi'. The two galleries are narrow and connect to a chamber surrounded by large, not very stable blocks, but between them one can climb up a few metres.

Returning to the previous gallery, after the step, we can continue along it, after descending a 1 metre step that leads us to a pit; from here, in the same direction as the step, an ascending gallery continues and crosses perpendicularly with a second gallery; this latter one is 7 metres long and allows us to stand upright at the N end of the gallery. The ceiling lowers, while the floor widens; on one side we can see a small pit of 1.5 metres.

If we descend the pit we had left behind, at the beginning of the ascending gallery, we can continue along a 4 metre crawlway to a small chamber from which, by means of a short gallery that continues horizontally and ends after a few metres, while if we descend the step, we can continue along a descending gallery that goes down among rubble to a point that becomes impracticable.
