It is a large worked and fitted-out rock shelter, it has dimensions of 65 m in length by 7.50 m in depth and a maximum height of 12.50 m. It is worked on two levels, presenting an arch 11.50 m wide by 7.50 m high.

In the lower area we find a channel that runs from one end of the rock shelter to the other, being an old wool washing facility, very singular, that operated between the 16th and 19th centuries. The dirty wool was placed in the channel to wash it and it was also washed in the basins that we find on the lower floor. The wool was dried on the upper floor, spread out exposing it to the sun and the wind.
