Yffiniac / Allineuc

Starting at Yffiniac, at the bottom of the Bay of Saint-Brieuc, strike south into the green countryside of inland Brittany. The route, along small roads, leads to the village of Allineuc and Bosméléac Reservoir, which used to provide the water for the Rigole d’Hilvern Channel, built to supply water to the Canal de Nantes à Brest.
