With 674 climb effort points this is the hardest one among this web site's collection of climbs in the Vosges. There are two reasons for this, namely the large number of meters to climb (964) and the relatively steep second part where between kilometer 11 and 14 the mean slope is 8.6%. The tour starts from Willer-sur-Thur at the junction of the N66 and the D1386. The first 9 kilometers up to Col Amic the slope is variable (2-8%) with the road winding through farmlands and forests, and passing the village of Goldbach-Altenbach. At Col Amic two other climbs join the climb described here to have the same itinerary to the top. After Col Amic the slope is generally steeper than before, especially in the middle part. At first the surroundings consist of dense forests but during the final 3 kilometers these give way to the more open landscape of the highest parts of the Vosges, allowing wide views. The finish is some 80 meters below the highest point of the Vosges (1424 m). Unfortunately the road is very broad and hence does not contribute to a high score of scenic beauty. On mid week days there is not much traffic.
