At Guipry-Messac, historically a significant port for transporting salt (once a precious commodity) inland, admire the imposing central mill on its island before continuing along the former towpath by the Vilaine. One highlight is Les Corbinières, a remarkable natural site with steep wooded sides. There are several river ports at which to enjoy a break along the Vilaine. The stage ends at Redon, an historic town at the confluence of the Vilaine and the Canal de Nantes à Brest.
The route follows the former riverside towpath. The surface is mainly of compacted sand. A few sections are along small roads with very little traffic.
