The chasm is 99 m around the rim with a diameter of 35 m. Visitors descend 75 m via a lift or a staircase before entering the cave system. It contains a subterranean river system that is partly negotiable by boat to see several spectacular settings with amazing limestone formations as well as cave pools
It is quite an experience for children and adults. In high season it is advisable to reserve. Although it is only 60 miles from Le Seguinet, it is an hour and forty min drive. It is a good out for the day.
