This relatively long route takes in part of Eurovélo 6, the main route between Nantes and Budapest (Hungary). You'll be able to cycle along the banks of the Doubs in complete peace and quiet. It's an ideal way to discover the diversity of the Doubs Valley landscape. This route will also take you through several villages where castles, churches and characterful houses stand side by side. The route leads to the base of Osselle and the famous Osselle caves in nearby Roset-Fluans.
