At the edge of a path, a stele in memory of the pilot who died when his Crusader crashed in the Tremelin forest.

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!!! 😊👍
