A wonderful area for cycling with interesting passes like Le Pillon, La Croix or Les Mosses.
Grands Tour Project suggested you 8 routes starting from Villars-Gryon, les Diablerets and Bex.
Around Bex you will find the easiest rides. Loops taking the Alpes Vaudoises passes are dedicated to well trained cyclists. You can go for 19 to 120 km.
