The entrance can be seen from the opposite side of the gorge near Tresviso. To reach it follow the pitch made path between Tresviso and la Cueva del Agua at the head of the Urdon Gorge. Follow the path to Beges, until this crosses the canal and climbs up


This is 6m high and lm wide, on a slope (steep) among trees. It is not easy to find.


The cave itself is a massive fault chamber about 400m long and up to 50m high, containing enormous formations Inside the small entrance a scree slope enters a chamber 7m wide and about 10m high. In the late afternoon the sun casts its rays directly to the floor, with stunning effect.

The cavern continues back, getting higher and wider, and for 60m is filled with massive collapsed blocks coated with flowstone and festooned with stalactites. Several routes are possible through this maze, the easiest being by the right hand wall. The finest formation is found near the far end, a floor to roof column some 4m wide and 25m high. Near it a large stalagmite resembles a statue of an angel. Climbing down one gains a gently sloping floor made of grey, dry flowstone which sparkles as if with embedded diamonds. The chamber here is some 15m wide and 25m high.

A narrowing passage leads under huge boulders to the top of a long boulder slope at the start of a crescent-shaped hall. This awe-inspiring final chamber is 170m long, 40m wide and the roof is mostly beyond the range of our carbides. The whole of the left hand side wall is covered with cascades and terraces of orange flowstone. At the far end of an unstable scree slope, calcited in places, rises up for 120m to a choke. Dotted throughout the chamber are large stalagmites up to 2m high looking like piles of pancakes, formed as the drops of water falling from the roof are scattered on impact.

There are no side passages, in the centre of the right hand wall, a small (14m by 10m) grotto containing exquisite white formations.
