A depression with chestnut trees contains a number of entrances all of which unite at a 9m pitch. At the base, 30m of walking lead to a climb of 7m and then varied going to a large chamber. An inlet can be followed for 60m to its end at two large avens.

Downstream the passage closes in and ends at a strongly draughting, tight, muddy crawl. This is close to, but apparently at a higher level, than the Gorilla Walk in Cueva de la Hoyuca (107). A dye test has shown a connection to the last inlet on the left in the Gorilla Walk.
