Cross the Alps meeting people and mountains... The Grande Traversée des Alpes (GTA) between Lake Geneva and the Mediterranean is a long-distance hike. The opportunity to take a long break and put daily life aside.
This itinerary runs along the Swiss and Italian borders while crossing five counties and some of the most famous mountain ranges in the Alps.
2nd section: Mont-Blanc, Beaufortain, Vanoise
This section leads from the giant glaciers of the Mont-Blanc massif to those equally imposing of the Domes de la Vanoise. On our way, collections of milk cans remind us of the authenticity of farming life in the Beaufortain pastures and then on the Vanoise the first National Park in France, created in 1963, land of ibex and marmots.
One of the benefits of being with a guide is the opportunity to discover some beautiful variants and mountain passes stress-free! The chance to feel alone in the world, in the vast preserved Beaufortain and Vanoise areas.
