Discovered by the Tour de France, it is now a legendary mountain. I recommend the climb from Culoz with its spectacular hairpin bends and great views of Lac du Bourget. 17 km ascent, partly up to 14% incline, but with 2 longer flat sections that allow some relaxation. Wonderful all-round view at the summit, with snack bar and souvenir shop in the nice season.
