Col du Granon
D234TSaint-Chaffrey to Col du Granon
One of France’s highest paved cols, a steep dead-end above Briançon.
The narrow D234t climbs the south side of the Col du Granon to 2,413 m above Saint-Chaffrey near Briançon, making it one of the highest paved roads in France. It is a relentless dead-end climb, gaining over a kilometre of height in about 11 km at gradients around 9-10%, and it hosted Tour de France summit finishes in 1986 and 2022. The tarmac ends at the pass, the road is narrow with few barriers, and it is closed by snow outside summer.
