The entrance has a tree. First pitch of 20m is choked at the base but has a small letter box through to the head of a 12m pitch. There is a 20m long passage at this level which is entered by traversing.

The final 22m pitch is particularly black and uninviting and continues another 20m but becomes too tight. A traverse over the final pitch leads to an 8m shaft and a choke.

The shaft is close to the linked shafts of Torca del Triveno (617) and Sima Levantada (578) but is connected to neither.
