The 19-kilometre route will give you the chance to discover the Haut Val de Bagnes as well as the Mauvoisin Dam. At 250 metres high, it is the tallest arch dam in Europe and is situated at an altitude of 1,960m. Start your itinerary in Le Châble and follow the Route de Mauvoisin.
You can take a break halfway through the itinerary in the village of Fionnay. The village is mostly made up of old mazot huts, which lend it an authentic charm. The real climb begins here, and the route becomes progressively narrower and wilder. You will discover unspoilt nature and a breathtaking panorama.
Cross the hamlet of Bonatchiesse, which benefits from a peaceful and natural setting. Once you arrive in Mauvoisin, you will have the option to cycle up to the dam – it’s well worth the detour to see it!
