The Arc Gorges
Park near Fort Marie-Thérèse, shortly after Villarodin on the Modane - Bramans road. Start on the "Traversée des Anges" klettersteige and go left. There is an opening in the barbed wire along the path. It gives access to another path that goes down to the start of the routes.
50m rope - The two routes are very demanding and athletic, so save your strength!
