Col du Télégraphe is a mountain pass in the French Alps situated above the Maurienne valley between the eastern end of the massif d'Arvan-Villards and the massif des Cerces. It was last used on Stage 17 of the 2017 Tour de France, with Primož Roglič leading at the summit before tackling the Col du Galibier.
The Fort du Télégraphe, the semaphore station which gave the pass its name, marks the summit and is just visible on the peak ahead of you as you cross the river L'Arc at the start of your ride.
