The Col du Grand Ballon (elevation 1343m (4,406feet)) is a mountain pass situated close to the summit of the Grand Ballon (14240NaN0) in the Vosges Mountains of France. It connects Cernay (Haut-Rhin) with Le Markstein winter sports station.
There are several different directions from which the Col du Grand Ballon can be climbed:
From Cernay (south-east), the total distance is 23.3km (14.5miles) at an average gradient of 4.5%, gaining 1046m (3,432feet) in height. This route follows the Route des Crêtes over the Col de Herrenfluh (8350NaN0) after 9.5km (05.9miles). After a short descent, the road climbs again to the Col de Silberloch (9060NaN0) before descending to the Col Amic (8280NaN0). From here, there remain 6.8km (04.2miles) at an average of 7.6%. In the forest on this final section, there are two short paved stretches. 3km (02miles) from the summit, the gradient increases to over 8%.[1]
