The climb is steep, but manageable. The view from up there, stretching far into France, is definitely worth it!

One of the best refuges I have visited, very clean facilities, if you want you can have lunch, they have a very correct menu. Very well equipped terrace to rest in the shade, with spectacular views of Parc de Sorteny. We arrived by taking a nice walk with the children from the Zone where you can leave the car.
