Departing from Avanne, this route will take you to discover the hills of the village of Ranceney. After a relatively flat and non-technical first part, you will climb on the heights of the Bois de la Côte by a forest path that will quickly give way to a technical trail on ridge, offering exceptional viewpoints over the Doubs valley. Vigilance will be necessary on these ridges, sometimes with narrow paths. You will then descend on Ranceney village before going around the Bois de Rapin along the Doubs, in a wild and enchanting forest atmosphere. Back on Ranceney, you will find a non-technical land and then return to Avanne quietly by the path taken to go.
