Above 'La Mesa', near Tresviso village. From Tresviso follow path climbing up on the eastern end of 'La Mesa', following a small valley at the junction of the sandstone and the limestone. Once you reach the plateau, continue for about 300m until you reach three cabanas. The entrance lies 100m up the slope, above the last of these cabanas.


The entrance is hidden in a rock outcrop. It is about 2m long, and 0.5m wide, with a large boulder straddling the drop. (This makes a good belay).


Below the entrance is a pitch of about 40m down a shaft which bells out slightly to a cross-section of 4m by 3m. There are numerous ledges, covered with loose boulders, mud and dead sheep. The rock is rotten and brittle. A parallel aven can be entered at one point on the descent.
At the foot of this shaft is a boulder floored chamber, into which both avens enter. Two parallel pitches of 16m lead into a lower chamber from which a small stream trickles down a further 10m, which can be free-climbed. At the foot of the climbs, a small rift passage can be followed towards Tresviso for about 6m and then becomes impassably tight.
