The entrance of Caverna La Gran Galería is located at the bottom of a 100m long and 70m wide doline. The portal is 33m wide and 15m high, with three access points to the cave passage. The main passage runs for 35m to the west, then 50m to the south.
The cave entrance was locally known, but the cave was first explored by Gordon McCracken and Carlos Goicoechea in 1989.
