The bay of Les Saintes ranks among UNESCO’s list of most beautiful bays in the world—and it’s not hard to see why. The views, whether on approach from the sea or from atop one of its bluffs, make up a dreamy Caribbean postcard, with the bluest of waters punctuated by small sailboats and a few docks, and its shores lined by sugar-white beaches. Under its surface, coral reefs thrive, making it an excellent snorkeling and diving destination. Lazying on a catamaran drifting across the bay is also a worthwhile experience, whether you get into the water or not.
