From Ray-sur-Saône, take the D27 county road to join the Saône’s banks. Continue along the Saône’s west bank up to Autet, then cross over to the east bank up to Gray. You then follow the Saône’s towpath, short stretches of which are open to traffic.
At time of writing, this stretch is signposted Charles le Téméraire.
Be aware: along the sections that are closed to ordinary traffic, note that you may still encounter service vehicles and anglers’ cars.
