Entrance A is 1.35×1 metres. The shaft is 4.20 metres. The gallery is 2.80 metres wide at this point. The left-hand gallery ends at 6.70 metres. The parallel gallery is about 4 metres long. The triangular crawl is 0.75×0.50 metres. The right-hand gallery is about 11 metres long, 1.60 metres wide and has a maximum height of 3.55 metres. The passage is 1×1.28 metres.

If we enter through the higher one (entrance A), we will descend a r-1.60; a small ramp leads us to a 4.20-metre shaft, downclimbable with a little care. This small shaft leaves us in a gallery; on the opposite wall we find a funnel that takes us to the deepest point of the cave: -11 metres. If we head to the left, the gallery ends at 6.70 metres; in this stretch there is a parallel gallery, to our left, about 4 metres long, accessed through a triangular crawl of 0.75×0.50 metres that returns to the gallery further on through a narrow fissure. If from the base of the shaft we head to the right, we will advance along a gallery about 11 metres long, 1.60 metres wide and with a maximum height of 3.55 metres. A passage of 1×1.28 metres leads us to climb 2.50 metres to reach the base of the small shaft of the second entrance (entrance B); climbing a r+1.90 we come out to the exterior.

Entrances opened by digging; they remain covered by snow part of the year.
