Attention!! The GR descending towards the bottom of the Wolf Room is currently strongly discouraged following the recent bad weather I suppose but remains accessible all the same. A small barrier with a warning is located at its base, in the ascending part. Everything remains passable on the descent.... but be careful!!! 😊👍

Magnificent leisure center with various activities. The tour of the lake is carried out without difficulty by a sandy path for its entire length of approximately 5km.

Pay attention to the descent from the point of view of the chamber of wolves, more typical of mountain biking than gravel, with a good technical aspect in wet weather.
