Col de la Croix de Fer
D926Saint-Jean-de-Maurienne to Saint-Colomban-des-Villards
A wild, multi-summit Tour de France climb.
The D926 over the Col de la Croix de Fer at 2,067 m is a storied, irregular Tour de France climb above Saint-Jean-de-Maurienne, false flats, sharp ramps and a remote, beautiful high valley below the Aiguilles d’Arves. Demanding and exposed; expect cyclists, livestock, and winter closure.
