For the best seclusion on Great Harbour Cay's 7 miles of beach, move to its second main beach 5 miles north, where rock bluffs divide the gorgeous, fine white sand into "private" beaches roughly 1 mile in length. Exploring the Sugar Beach Caves is an added attraction. The calm waters along these coved beaches make them great for snorkeling. Amenities: none. Best for: solitude; sunrise; snorkeling; swimming; walking.
