From one side of the Alps to the other, discovering mountains and people... The Grande Traversée des Alpes (GTA) between Lake Geneva and the Mediterranean is a long-distance journey. It's a chance to put your everyday life on hold! The route skirts the Swiss and Italian borders, crossing five French departments and some of the best-known mountain ranges in the Alps.
2nd section: Mont Blanc, Beaufortain, Vanoise
This section takes you from the giant glaciers of the Mont-Blanc region to those of the Dômes de la Vanoise, just as imposing in terms of the surface area they cover. And along the way, collections of milk cans will remind you of the authenticity of the pastoral life of the Beaufortain mountain pastures. There's no room here for industrial livestock farming, even if cow herds often number over 150 head. It's also a route between three major Alpine valleys: the Chamonix, Tarentaise and Maurienne valleys.
