The entrance of Caverna La Gran Galería is located at the bottom of a 100 m long and 70 m wide doline. The portal is 33 m wide and 15 m high, with three access points to the cave passage. The main passage runs for 35 m to the west, then 50 m to the south.

The cave entrance was locally known, but the cave was first explored by Gordon McCracken and Carlos Goicoechea in 1989. One year later a team of cavers from the United States surveyed the cave and drew a Grade 5 map. At this time the farm were the cave is located was owned by Jorge Vidal, called Chiricano. He sold the farm to a man named Alvin, who started to prepare it as a show cave.
