The Col de Herrenfluh is located at an altitude of 837 metres in the Vosges, between Uffholtz and Wattwiller. The summit is located along the Route des Crêtes and offers magnificent views over the Rhine Valley and the surrounding forests. Nearby are the ruins of the Château du Herrenfluh, which was once an observation post during the First World War (but difficult to reach for a cyclist).
