Departing from the Avanne sports complex, this itinerary will lead you to the discovery of emblematic places in the area, from the Valmy Rock to the Planoise Fort through La Roche Trouée and the castle ruins of the Côte d'Arguel, offering you superb views on the meanders of the Doubs Valley. An itinerary with a very varied profile, on different terrains, alternating passage in the undergrowth, in the dry lawns and through hamlets bisontins. You will run on tracks, paths or tight trails. A very beautiful loop that will seduce you with its diversity.
