The cave is also of archaeological interest, because Indians once lived in it—a fossilized skeleton was found here, and there are rupestrian drawings, as well.  Bats, blind fish, reptiles and other mammals live in the area. At the entrance to the cave, visitors are provided with helmets and lights, which are required equipment.  Groups may consist of up to 20 people; each group has a leader and an assistant, who tell visitors about the evolution of caves and the history of man’s exploration of them.

The main attraction of the tour is the great variety of the cave’s formations,; which have been called “the reign of stone mushrooms” because of the shapes of its stalagmites, which run from a few inches to 10 feet (3 meters) in height with some of them standing in solitary isolation while others form veritable forests.  The roof of the cave is literally covered with stalactites, and you’ll see formations in the shapes of columns, cloaks, gours, helictitas,; curtains, cave pearls and bells during your tour.
