The only obvious entrance found in the vicinity of Las Bobias, this is in a small cliff face at the top of a tree-clad ridge rising up from the 'fuente'. The passage descends into a large chamber filled with rubbish, such as gas canisters. Side passages to left and right lead respectively to a blind end filled with cheeses, and over a low metal door and small wall to more cheeses. A shelf 3m above the floor level contains a very tight, vertical phreatic tube which was not investigated further.
