A beautiful swimming spot where you can go by paddle boat. Afterwards you can take a break on the rocks and even jump in.

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.

On your right, you will see a path that you can take to see the Réméjadou sinkhole. Be careful because the sinkhole is deep and the surroundings can be slippery.

A great swimming spot with rocks in the water. In the rock face by the water there is an entrance to a cave into which you can go several meters. Has scary factor. ☺️

You can easily go a few meters into the cave. Flashlight definitely useful.

Great little cave. Flashlight and let's go. Goes in a few meters and gets very dark quickly.

you can enter the cave a few meters deep normally. After that it gets a little tighter and we didn't dare go any further. Maybe next time.☺️
