Col du Télégraphe

Col du Télégraphe, a scenic Alpine road

Col du Télégraphe is a high mountain pass at an elevation of 1.566m (5,138ft) above the sea level, in the French Alps situated above the Maurienne valley between the eastern end of the massif d'Arvan-Villards and the massif des Cerces. The pass is traversed by the scenic Route des Grandes Alpes.

The road over the pass is asphalted. It's called D902 and links Saint-Michel-de-Maurienne to the north and Valloire to the south, as well as forming an access point to the col du Galibier via its north face. The Col du Telegraph is so named because at the very top of the climb there's a fortress, the Fort du Télégraphe, that used to have a semaphore telegraph on top of it, built in 1884. The Fort du Télégraphe is open for visitation during the summer months. On the summit there are some radio and TV towers. It's a rather large cement structure that can be seen for a long way.

The Col du Télégraphe has been crossed multiple times by the Tour de France. To reach the Col du Galibier, you must first climb the Col du Telegraphe. The road is normally open the whole year around. It has a maximum gradient of 10% and 14 hairpin bends.
