Once at the col, carry on along a clearly marked 4-wheel drive track, which will take you up to the Col to Cluy. Next, descend to the left to the Pont des Envers bridge (but don't cross it) and follow the left bank of the Sarenne to the Col de Sarenne. Ride down from the col to Le Perron. There is a path on the right to avoid riding a part on the road. Follow signs to Clavans-le-Haut and then Clavans-le-Bas on the GR 54. In Clavens-le-bas, stop off for some homemade blueberry tart before the climb up to Auris. From Clavans, follow the road towards Mizoen and 200 m after the junction of the road to Besse, take a path off to the right, signposted "Oratoire du Follet / Puy-le-Bas". This spectacular section is quite technical and physically demanding. The path winds its way pleasantly through cool woodland, before emerging into full light onto the panoramic path that leads to the oratory of Le Follet. Shortly after the oratory, take a right-hand path up towards "Puy-le-Haut / Puy-le-Bas. Take care on this path made up of loose stones. From Puy-le-Bas, carry along the road to Puy-le-Haut. Before arriving in Puy-le-Haut, take a left-hand path signposted La Croix de Trevoux, then continue upwards to the hamlet of Les Cours. On this south facing slope, the vegetation changes, making you feel more like you're in the south. From Les Cours, ride to Auris on the road. At La Chapelle Saint Giraud, you have the option of taking the small waymarked path (XC 4), which will take you up Auris above the road.
