Castelbrac Hôtel & Spa occupies a former Belle Époque villa and marine research station on the cliffs of Dinard, facing the Bay of Saint-Malo and the Emerald Coast. Its 23 rooms and suites are arranged within the historic structure, combining maritime references, Art Deco details and broad sea views. Pourquoi Pas restaurant and the Aquarium Bar make the waterfront setting part of the hotel’s social spaces, while the spa and narrow swimming corridor are tucked into the cliffside property. Guests can also take to the water aboard Fou de Bassan, the hotel’s private boat, directly extending the experience into the bay.
