Val Ferret

The two valleys are connected by a mountain footpath through Col Ferret which forms part of the 170 kilometres (110 mi) circular Tour du Mont Blanc route.

The main villages of the Val Ferret are (descending from the pass): Ferret, La Fouly, Prayon, Praz de Fort, Issert and Som la Proz, all belonging to the municipality of Orsières.

From the Col Ferret (the Swiss border), the valley runs down, beneath the Pré de Bar glacier and the towering Grandes Jorasses.

The stream running through the valley is the Dora di Ferret (French: Doire de Ferret), which, near La Palud (in front of the Italian Mont Blanc Tunnel exit), joins the Dora di Veny (French: Doire de Veny) flowing down from Val Veny to form the Dora Baltea, a left-hand tributary of the Po.

The main villages in the valley are Arnouvaz, Planpincieux and La Palud, all in the comune of Courmayeur.
