Leaving Saxon in the heart of the Rhône Valley, the first switchbacks of the route wind through meadows and orchards where apples and apricots grow. These first few kilometres follow the Torrent des Croix and cross the hamlets of Sapinhaut and l'Arbarey. You will pass through mountain pastures as you tackle the route's countless hairpin bends. Little by little, the view over central Valais below opens up into a panorama stretching from Martigny to Sion. As you approach the summit of the pass, the Pierre Avoi mountain, which dominates the climb, becomes increasingly massive and impressive. The last few hundred metres on compact gravel lead through to the forests of Val de Bagnes. The end of the climb reserves one final surprise: a short stretch of unpaved road that adds an extra dose of charm to this unmissable route!
