Col du Granon (el. 2,413 m or 7,917 ft) is a high mountain pass in the Alps in the department of Hautes-Alpes in France. A narrow tarmac road winds steeply up the southern approach. Gravel roads continue beyond the pass, in a military training zone.It hosted the highest ever mountain-top stage finish in the Tour de France—once only—in 1986, until the 2011 Tour de France, that had a finish in the Col du Galibier, at 2,645 m (8,678 ft) of altitude.
