Itinerary description

The itinerary begins in Piazza Abbé Henry, along the street of Strada del Villair.
You stay on the road that, uphill, leads out of Courmayeur to the hamlet of Villair Superiore (1,325 meters), continue up to a well-marked junction, and cross the bridge over the stream.
On the left, a path through the trees allows you to cut some hairpin bends. Turn right and take the path, signposted TMB, with signs for the Bertone refuge.
From the junction on the road, you reach the village of Le Pré, dominated by the refuge Bertone (1,989 mt). Just before arriving at the refuge, you can enjoy a wonderful view of Mont Blanc, the Aguille Noire du Peuterey, and 700 meters below, Courmayeur. Following the path to the right of the refuge, you reach a panoramic table (2,030 meters) where the path divides: on the left, it proceeds to the Val Ferret along the route of the Tour du Mont Blanc, on the right, it climbs towards the ridge of Mont de la Saxe.
Following the Val Ferret and the Bonatti refuge, the path creeps through thickets and meadows always offering priceless views: when you fork upstream of the ruins of Alpe Lechey (1938 mt) you continue on the main path and get behind the Alpe Léche (1.929 mt). After a few ascents descend into the middle of the pastures, past the
Vallone di Arminaz, you reach the refuge Bonatti (2.025 mt). and the beginning of the Comba di Malatrà.
