The entrance appears as a small rock shelter 10 m wide. Immediately after comes a vertical step almost 1.5 m high that leaves an opening 6 m wide but very low, so that we have to enter almost lying down. It gives way to a chamber 12 m long by 9.5 m wide. The ceiling is completely flat and horizontal, coinciding with a bedding plane. In the centre of the chamber we can walk upright, but towards the sides we have to stoop. At the end of the chamber there is a low, descending passage that leads us to a sort of gallery which, after making an elbow, comes out into the chamber again.

The dominant morphology of the cave is clastic, with the floor almost entirely covered by slab-shaped blocks originating from strata that have come away from the ceiling.

A later phase of lithogenesis covers a good part of the blocks, so that these have become cemented to one another by the concretion. Through this same lithogenic phase, the cave has concretion-covered corners, with stalactites and small stalagmitic masses.

To get there, we will set out from Beuda and take the partially asphalted track towards Lliurona. On reaching the coll de la Creu we will take a track that leaves to the left in order to leave the car when it passes beside the stream, which soon becomes a gorge. We will go down to find the stream and follow it a little downstream. Just when we have left on the left a shady corner where a tributary stream arrives, we will go up the left bank and shortly reach the cave. Since the cave hangs 12 m above the bed of the stream, a traverse with an awkward step is necessary just before reaching it. From the car to the cave, about 12 minutes.
