Open your eyes and enjoy the amazing view of 4 mountain ranges on this easy hike. From the Foyer de Fond du Barioz, a trail takes you to the plateau where the Crêt du Poulet refuge is located. Follow the path to the Grand Rocher Cross.
You will climb up to the plateau on a fairly gently sloping trail. You will then cross the Crêt Luisard wetland, a protected area. The summit is not far away, with views of the Haut Breda (Belledonne) and the Chartreuse, Vercors and Bauges massifs.
