Grand rock shelter 120 metres long, 34 metres deep and 15 metres high, opened at the foot of a crag enclosed in a torrent, which at this point becomes quite wild. An exuberant vegetation of trees and lianas situated outside disguises, to a certain extent, the great elongated mouth of the rock shelter, giving it a shady and damp appearance, increased by the presence of the little stream that flows through it. According to the topographic data it is calculated that the total sheltered surface is 3150 square metres. The rock shelter is excavated at the base of a compact stratum of marly limestone from the eocene, which rests on a softer marly level. The torrent, after overcoming the crag by means of a waterfall, has been undermining its base, at the contact with the underlying marls, being responsible for the formation of the rock shelter.

From the back of the rock shelter water springs from a small hole, having originated a tufa stone concretion around it.

It is traversed by the stream that formed it. From the back of the rock shelter water springs from a small hole; the spring is beautiful and abundant, although it can run dry in times of drought. Formerly, this spring (Font de Can Solà) fed a large reservoir to irrigate the cultivation terraces that extended below the old road to Igualada.

Inside the rock shelter there is an enclosure formed by three walls, where in other times they would keep the flock.
