The route is accessed from the French side at Col de La Seigne (2591 m.); from there follow the upper Val Vény as far as the Elisabetta Refuge then descend toward Lake Combal.
After passing the Arp Vieille pastures and Lake Chécrouit, you come to the cosy Maison Vieille Refuge, the last chalet at altitude before dropping down to the valley bottom, to Dolonne and then to Courmayeur.
Go through the town and to Val Ferret by the path running from Villair on the outskirts of Courmayeur to the Bertone Refuge.
From there, a long footpath becomes a panoramic balcony overlooking the Mont Blanc chain: the Aiguille Noire de Peuterey, the peak of Mont Blanc, the Dent du Géant, the Grandes Jorasses.
The route passes first the beautiful Bonatti Refuge and then the Elena Refuge, then goes up to the Col du Grand Ferret, on the Swiss border.
It goes through Fouly and Champex in Switzerland before crossing into France by the Col de la Balme, near Chamonix and Les Houches; finally, the Col de la Croix and the Col de La Seigne bring you back into Italian territory.
