Route des Crêtes, Vosges

The Vosges ridge road from Cernay: the long climb to the Grand Ballon at 1,340 m, then north along the Route des Crêtes over the Markstein, the Col de la Schlucht and the Col du Bonhomme before dropping to Sainte-Marie-aux-Mines. Nearly 90 km of high-mountain road and 1,800 m of climbing.
