a beach club on the ramparts of the intramuros(walled city) of Saint-Malo where you can rent kayaks…read more& hobie-cats. and best of all, swim in the seawater pool(at high tide, the pool is entirely submerged by the sea except for the diving platform). definitely a safe and popular alternative to the open sea. there's also a bar for drinks, burgers & frites(shoes/shirts not required).
