A beautiful loop through the Haut Juras – finishing with a superb climb through and above the Gorges du Flumen (map below).
The ride starts off easily enough along a typical Jura plateau, eventually reaching Col de la Croix de la Serra.
From here on the route is surrounded by huge cliffs and lovely country side.
The best is saved for last. From Saint-Claude, the climb through the gorgeous Gorges du Flumen – and above on a little road. It is almost 800 metres vertical climb. Hard work, but worth the effort.
