Opened in 1920 by the Touring Club de France, the Route des Grandes Alpes links Lake Léman to the Mediterranean Sea.
From Thonon-les-Bains to Nice, 720 kilometres of mountain roads, dotted with 17 passes which are among the highest in the French Alps, invite you on a trip across territories with a truly exceptional natural and cultural heritage.
La Route des Grandes Alpes goes through Barcelonnette in the Ubaye, over the fabulous passes of the Col de Vars (2,109 m) and the Col de la Cayolle (2,352 m) and alongside the Mercantour National Park.
