Leave Marennes on a designated track which follows the length of the RD 728E. Take care when crossing the bridge over the Seudre. Cycle lanes continue through the national forest. There is a magnificent track along the section coming into La Palmyre. Upon leaving the Palmyre, the route crosses the pine forest to very quickly rejoin the coast: the greenways stretching along the coastline can in places be covered by sand. Take care when crossing Saint-Palais-sur-Mer and Royan, with cycle lanes often on busy pavements. Be prepared to have to move onto the road, particularly when traffic is heavy. At Royan there is a SNCF train station connection : be careful as some intersections can be tricky, notably Boulevard de la République, Cours de l'Europe and La Place du Docteur Gantier.
