ITINERARY
> From the Auris-en-Oisans parking lot, take the path towards the Col de Maronne. At the pass, continue right on a well-marked 4x4 track to the Col de Cluy.
> Then descend to the left as far as the Pont des Envers (do not cross) and follow the Sarenne torrent on the left bank as far as the Col de Sarenne.
> From the col, descend to Le Perron, where you'll find a path that avoids a section of road. Look on your right. Follow the GR 54 towards Clavans-le-Haut then Clavans-le-Bas.
> From Clavans, continue along the road towards Mizoën. 200 m after the Besse intersection, take the small path that climbs to the right towards "l'Oratoire du Follet / Puy-le-bas". This spectacular section is fairly technical and physical. The route winds pleasantly through cool undergrowth, then springs back to life on a panoramic path to the oratoire du Follet.
> Shortly after the oratory, take the path on the right towards Puy-le-Haut / Puy-le-Bas. Be careful on this narrow path of rolling stones.
> From Puy-le-Bas, continue along the road towards Puy-le-Haut. Before reaching Puy-le-Haut, take the left-hand path towards "La Croix de Trévoux", then continue gradually uphill towards the hamlet of Cours. On this south-facing slope, the vegetation changes and becomes more southerly.
> From "Aux Cours", climb the road towards Auris. At Chapelle St-Giraud, you can take the small signposted path [XC 4] which climbs up to Auris, overlooking the road.
