There are no crowds here, just you, the mountain, the wind, and the sensation of pedaling on one of the remote peaks of the French Alps. The summit, at almost 2,000 meters, offers a 360° panorama that erases fatigue and ignites the cycling spirit.

Fully paved and much less busy than Alpe d'Huez, the Col de Sarenne connects Mizöen to the famous ski resort. A true natural spectacle!
