Giant Chasm of Cabrespine

The Giant Chasm, located 25 km from Carcassonne, dominates the small village of Cabrespine nestled in the heart of the Clamoux gorges, at the foot of the Pic de Nore (1211m).
Visiting this 6 million year old natural wonder is discovering one of the largest caves in the world, which is one of the ten most beautiful caves in Europe!
A geological jewel, it is renowned for the richness of its crystallizations.
Glass balcony, caving exploration and light shows give the place an even more spectacular dimension.
