The vast forests that you will cross are managed by the National Forestry Office. Although located on the territory of Vassieux-en-Vercors, which is responsible for the maintenance of forest roads (as these are communal roads, they are the public property of Vassieux), the forests themselves belong in reality to the town of Die and the town of Marignac-en-Diois. The benefits of the exploitation of wood therefore escape the commune of Vassieux.Before 1911, Vassieux was administratively attached to Die. The story goes that the municipality, unable to pay taxes, would have donated the land to pay its debts, which would explain the current situation.
