Description of the route

When you reach Isollaz along the tarmac road from Challand-Saint-Victor, leave your car in the car-park and take the path above the hamlet, which goes uphill crossing the road to Dondeuil several times, as far as Suc and Fontaney. From here you continue on the un-made road towards the Alpine pastures of Chavernasse, Chalex, Dondeuil Désot and Damon, where the road finishes. From here you take the footpath which climbs along the valley until you reach Col Dondeuil.
