The entrance, above the sloping track, is a wide pitch of 11m. A stream enters from a stream passage 5m up the right hand wall. The water pours down a blind 10m pot and the way on is over this to a small vadose passage which leads after 75m to a small climb and pitch of 6m. A small zig-zag passage then runs to the head of a 25m pitch. At the base, the passage slopes down to a tiny static sump. A hading rift from here ascends to an aven where it is possible to get a voice connection with the top of the 25m pitch.

A dry crawl under the north wall of the entrance chamber leads to a blind 10m pot.

By using a different belay point a second series of seemingly unconnected passages can be entered by swinging on the ladder to a hole in the south wall of the entrance shaft. A short passage ends at a fine 23m pitch which is followed by 40m of tight canyon to a 6m pitch. The boulder slope is followed down. A climb up to the right closes down while a climb to the left needs looking at.

The 1992 extensions start by climbing down through the boulders to a squeeze into a narrow rift pitch. Downstream leads to a flatout section which can be bypassed. The route slowly increases in size and leads to a climb and a ladder pitch down and immediately another pitch (sizes?) to a small chamber and passage which eventually became smaller.

A short distance before a small inlet which goes 40m splits and chokes. The left hand branch chokes, ending in a short section of rift. A climb up in the roof enters a section of well decorated phreatic passage ending in a sandy, easy dig.

Opposite this section of passage, an easy crawl enters a 5m diameter conical shaped chamber with a way out which ends in tubes and climbs up which need pushing.

Upstream at the base of the ladder pitch mixed going divides - the left hand section ends in a choked rift and the right hand needs a little digging to enter a small continuation.

The cave comes close to Torca de Simón 2 (766).
