From Tréhiguier Harbour, a major centre for mussel farming on the Vilaine estuary, continue on to the Ménard dunes, wild sandy islets where peace and tranquillity reign. The rocky headlands along the coast will then lead you to the cliffs of the Mine d’Or.
Your route continues through the Bay of Pont-Mahé in Assérac, where, if you feel like it, you can stop for a swim the water can reach 25°C in summer! Finally, round off your ride in style at the Pointe de Pen Bé.
