The Green Spring

Highlight • Cave

The green spring or the Cuse is located on the left side of the river at approximately the same height as the blue spring. This is the true source of Cusancin. The upper gallery of the cave was walled with dry stones.

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.

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
