The Aven du Réméjadou constitutes an impressive opening on the Plateau des Gras onto a vast underground network, submerged almost over its entire length. Isolated in the middle of a forest of shaggy oaks in a ruiniform and chaotic environment of large blocks of limestone, the entrance is characterized by a deep gap. 26 meters high, the well opens directly onto an underground river that can be heard very clearly from the entrance. In heavy rains, the waters of the river sometimes rise up the well with a roar which can then be perceptible from afar. Given its characteristics, the exploration of this network where exposed sections are rare remains the almost exclusive domain of seasoned cave divers.

The visit to the cave is worth the detour, it is possible to go quite far inside. The ground is wet and sticky (like wet clay), there are beautiful cavities to observe. Provide a good flashlight because quickly you can no longer see the entrance or the light of day.
