Step-by-Step Route Description

Begin on the main street of Saint Michel de Maurienne (road D1006), turn right onto D902, and follow signs for Valloire, Col du Télégraphe, and Col du Galibier.
The ascent to Col du Télégraphe is a steady ride along a mostly tree-lined road, providing some shade in summer. The climb averages just above 7%, and a restaurant awaits at the top of the col if you need a break.
After topping out at Col du Télégraphe, enjoy a 4 km descent into Valloire. This Alpine town is an ideal place to refuel, with several restaurants and shops on offer.
Leaving Valloire, the road climbs gently for the first 5 km, then gets steeper with gradients between 7% and 10%. Water sources are available along the road, with the last one roughly 8 km below the summit at a mountain refuge.
Approaching the top, cyclists will notice a road tunnel through the mountain. For the true Galibier experience, take the left road before the tunnel to finish at the summit. This final ramp can be closed early or late in the season depending on snowfall—always check local advisories before your ride.
Restaurants/snack bars are located near the summit from both the north and south sides, providing additional opportunities to rest and refuel.
From the summit, it’s possible to descend southwards to Col du Lautaret (2,058m), with further options to continue towards Briançon or head towards Le Bourg d’Oisans.
