Through an elongated, low-ceilinged entrance one enters a sort of square-sectioned flat-out passage; the gallery increases in volume as one advances. The floor is covered with dirt except for two very localized spots where small blocks are piled up. Two small ascending steps bring us to the upper part of the gallery, where we find two openings in the ceiling. The right-hand one, after passing an easy crawl, places us in a circular chamber 4X3 metres in floor area, flat but not exceeding 0.4 metres in height. If we follow the left-hand opening, a rather difficult ascending flat-out passage must be overcome, giving access to a sloping chamber where the great abundance of formation considerably hinders access up to +6 metres.

In the circular chamber of 4X3 metres we find a great quantity of stalactites and columns of small size.
