Le Château de Sable

Near the tip of the Breton peninsula, this eco-hotel is all glass and clean lines staring down the Atlantic toward the Presqu'île Saint-Laurent. Book a sea-facing room; the garden side is fine, but the ocean views are the whole argument. A spa runs massages, Ayurvedic treatments, and Hatha yoga, and two restaurants cover the full range from brasserie to Michelin-starred fine dining without making you leave the property.
