An almost vertical descent of almost 60 meters beneath the surface until you reach the enormous “Sabbath chamber”. At the deepest point of the cave, you will enjoy a sound- and light show which accompanies the slow ascension of a miniature hot-air balloon, while gradually and dramatically revealing the stunning concretions which cover the cave walls.
The “Cataclysm” chamber - which was until very recently not open to visitors - will definitely leave a lasting impression.
Science enthusiasts will be delighted by the film “Videokarst��� which is shown in the reception pavilion, as well as by the “Maison des Guides” area where scientists closely observe the earth’s crust every movement.
