Matignon / Pleslin-Trigavou
Should you have time on your hands, head up first to the seaside resort of Saint-Cast-le-Guildo to make the most of its beaches. The Vélomaritime route then takes you on smoothly via minor roads to Pleslin-Trivagou, which you reach riding along a stretch of the Dinan-Dinard greenway. On the way, stop at the Château du Guildo, enjoying exceptional views of the Arguenon Estuary.

Take care crossing the Arguenon River via the Pont René Pléven bridge along the RD786 road.
⚠️ Saint-Hubert Bridge over the Rance is currently under construction: cyclists may cross on foot.
ℹ️ Complete bridge closure from November 2, 2026, to January 22, 2027, Monday to Friday from 8:00 AM to 5:30 PM; passage is possible on weekends and public holidays. Find out more.
