This route is the sixth and last one in our catalogue. It follows an (almost!) straight line along the Jura Mountains, beginning in the north at Crosey-le-Petit in the Doubs department (between Besançon and Montbéliard) and ending at Arbignieu in the Ain department. Riders wishing to explore the trail in its entirety will embark on a 500-kilometre ride, divided into twenty or so legs (with stop-overs in overnight group houses, horse farms, camp sites, etc.), while other riders can ride just a few legs.
