After the access to the heart of the caves by the electric train, the visit starts at the chaos room and continues to the tarasque hall where a rock seems to represent some fabulous animal.
The lakes and the concretions take curious forms. The mirages hall and the “gours” presents the most thrilling sight of a gabbled up city.
The biggest treasure is the hall of wonders, 2000 m² of visual effects where black lights make the alive concretions get phosphorescent.
