The ROUTE DES CRÊTES: from Cernay to the Bagenelles pass, the Route des Crêtes connects the main viewing points of the Vosges over 73 km.
The Route des Crêtes as it exists today was only built between 1930 and 1935 between Cernay and La Schlucht.
The Route des Crêtes facilitates access to the peaks of the Vosges mountains: the Grand Ballon (1,424 m), the Rothenbachkopf (1,316 m), the Kasterbeg, the Hohneck, the Gazon du Faing (1,303 m), the Brézouard and the lakes at the bottom of the valley. The Route also enables access to the Hartmannswillerkopf battlefield and military cemetery.
The Route des Crêtes, a former strategic road, is now the tourist backbone of the Hautes-Vosges.
THE GRAND BALLON: Le Grand Ballon (in Alsatian: Grosser Belchen) is the highest point of the Vosges mountains, the Alsace region and the Haut-Rhin department. It is located 25 km northwest of Mulhouse.
Some still call it Ballon de Guebwiller, named after the nearest town, 8 km to the east as the crow flies. It is 1,424 metres (1,423.7 m IGN) high.
From the summit and its orientation table, you can see Mulhouse, Basel, Freiburg im Breisgau, and Colmar in the plain in the foreground; the Black Forest and the Swiss and French Jura in the background; and even a large part of the Alps on a clear day, from Austria and Liechtenstein to the Mont Blanc.
