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!!! 😊👍
