Mainly on minor roads, with a stretch at the end of the stage along a greenway, from Tréméreuc to Pleslin-Trigavou. To avoid crossing the Rance Dam, that way proving too dangerous for cyclists, the route leads you along the Rance Valley.
Take care crossing the Arguenon River via the Pont René Pléven bridge along the RD786 road.
From the village of Matignon, a 3km link allows you to reach the seaside resort of Saint-Cast-le-Guildo.
Leaving Tréméreuc, there's a 9km link via a former railway line taking you to Dinard.
