After a small barrier and a small climb comes a nice point to rest. Attention, it is not recognizable at first glance. Behind the bush is a very small path.

High grotto with wonderful limescale deposits - accessible via a metal ladder even without equipment. The grotto does not lead deep into the rock, the daylight is sufficient, you do not need a flashlight. It is freely accessible to everyone.

On the other side of the train tracks up the hill are the wild undeveloped karst caves of Fourbanne, a dream for fans of speleology. Bring good light, rugged cloths, and wear your helmet (you're biking, so you have a helmet!). https://inpn.mnhn.fr/zone/znieff/430013670 See video https://www.youtube.com/watch?v=7nxTiEY92I8

The cave is listed as a real classic among speleologists. Through a very small shaft entrance of just 30 x 50 cm. you have to abseil about 7 meters ... Then the next 18 meter deep shaft. A final climbing step, about 5 meters lower, ends in an impressive and large hall with beautiful stalactite columns.
