The most feasible route to reach it at present is, at the entrance to La Palma de Cervelló, to head right toward the cemetery; shortly before arriving there we pass under a power line. We will have to go back up the path that climbs parallel to the line until it ends at a flat cross path; we will follow it to the left for a few metres and then immediately turn right, where the path climbs again. This brings us quite close to the base of the cliff where the electricity tower is. We will have to leave the path and follow some small trails along the E side of the cliff until we find the remains of a building; from there we can already access the base of the cliff toward the W. Before reaching below the tower, to its right, the small cavity is found.
