The cave Gouffre d'Esparros (Abyss of Esparros) in one of numerous potholes in the area. According to legend, it was discovered by a shepherd who had lost a lamb. In 1913 Austrian cavers tried to explore the cave and descended into the pothole, but could not discover a cave behind. In 1931 Norbert Casteret started another approch to explore the cave. After seven years of research he discovered the cave system behind the pothole together with his companion Germain Gattet in 1938. To protect the cave, the natural entrance was closed by an iron door in 1938.

Norbert Casteret used the cave during World War II to store secret documents. In 1942 the first radion report form a cave was made from this cave. In April 1945, at the end of World War II a mass was held underground inside the cave. For this purpose a statue of Virgin Mary was placed on a stalagmite. The statue can still be seen, in a chamber which is called salle de la vierge (chamber of the virgin) today.

After that the cave was almost forgotten, until in 1972 a study to develop the cave as a show cave was made. But the project was abandoned. In 1990 a second study was undertaken, and this time it was followed by the development and finally the opening to the public in 1997.

The entrance part of the cave consists of a labyrinth of narrow passages. For the development an artificial tunnel was dug which goes directly to the lower floor of the cave system from the nearby valley. This part is filled with extraordinary spelethems, especially aragonite.
