The source of the Doubs River is a powerful karst spring in a heavily karstified area of the Jura Mountains. It lies at an altitude of 937 meters at the foot of the forested, up to 1,419-meter-high Mont Risoux mountain range, which straddles the border between France and Switzerland. The Doubs River rises from a small, approximately five-meter-deep spring basin in a cave in the rock.

A lovely section of the mountain bike trail. Chamois encounters are almost guaranteed. Before descending to Les Charbonnières, there's a slight variation to the right, passing through an old ski jump.

Wide road from Vallorbe, lots of traffic, the first km is pretty steep. Juraparc near the col, with some goats and cute alpacas next to the road! An easier alternative to the Mollendruz to get into the Vallée de Joux.
