Concarneau's best beach is Plage des Sables Blancs, northwest of the town centre. Plage du Cabellou, about 7km south of town, is a decent spot for sunbathing and swimming, with views back to Concarneau; take bus 2, southbound, which continues all the way to scenic Pointe du Cabellou and its old fort.
Îles de Glénan
Sapphire waters, idyllic white-sand beaches and no crowds – Bora Bora? No: Îles de Glénan. This archipelago of around a dozen mini-islands lies just 20km south of Concarneau and never fails to impress in fine weather. Visitors are only allowed on Île de St-Nicolas. Vedettes de l'Odet runs scenic cruises around the islands from Concarneau and other coastal towns. Optional activities include sea kayaking and glass-bottom-boat tours as well as diving.
