L'Ile Ô Château

A boutique hotel parked just outside the walls of a 12th-century château on an Atlantic island better known for its potatoes than its lodging scene. Inside, the maritime theme gets a monochromatic, contemporary treatment that sidesteps the usual driftwood-and-rope clichés. There's a heated pool, a generous breakfast, and bikes to rent for exploring an island small enough that you'll run out of excuses not to.
