Clamouse Cave

At the heart of the Hérault Gorges, in the municipality of Saint-Jean-de-Fos, three kilometres from the medieval village of Saint-Guilhem-le-Désert, the Clamouse Cave contains a magical world. Discovered by potholers in 1945, it is now a listed Scientific Site.

On the guided tour, you can admire stunning concretions adorning the ground, ceilings and walls of the large chambers. This is the most diverse range of crystalline formations seen in France. Incredible-looking stalactites, stalagmites, discs and other shapes grace the walls, forming irregular lines. Bathed in magnificent crystalline glows or immaculate colours, they look dazzling thanks to the ingenious LED lamp lighting, the first of its kind in France. In the white corridor and the eccentric room, a truly extraordinary sight awaits you: incredible, winding lines of extreme whiteness seem to move in the rock. The draperies of stalactites and snowflake-like aragonite crystals are also among the treasures in this famous cave, a favourite among underground explorers.

For sportier visitors, a speleopark trail provides a chance to explore the cave in a more acrobatic manner while receiving an introduction to potholing. A fun and immersive itinerary!
