Take your friends cycling along the Voie des Salines between Arc-et-Senans and Salins-les-Bains to visit two UNESCO World Heritage saltworks sites.
Discover an unspoilt wilderness along the voie PLM which follows the old railway line. The PLM route crosses the first plateau before rising through the valley of the river Ain, passing close to Chalain lake.
Another suggestion for a lovely bike ride is a breathtaking section of the EuroVélo6 route, a whole succession of beautiful landscapes via Montbéliard, Besançon or Baume-les-Dames.
