The entrance is a resurgence upstream of an open air laundry area with a domestic water pipe.

The route drops into a low stream passage which ends at a sump. The upper level passage follows almost the same route with passable connections to the lower passage in four places. It ends at a static sump. There is almost certainly a connection with Torca de Simón 2 (766) which ends very close to the sumps.
