Small rectilinear cave with an appreciable ascending gradient and earthy floor. At its final part a bedding plane a few metres long ends the direct progression of the cavity.

Near the entrance and at a higher level, there is communication with an ascending conduit that goes a few metres further until it becomes choked; at this same level there is a window that communicates with the outside just above the access mouth.

To access the cave we will have to go down the old access stairs to the spring, located shortly before Km. 1 of the BV-1249 road towards Sant Feliu del Racó, which descend next to the weir. The base of the cave is a few metres above the base of the cliff, so a short climb from the base will be necessary.
