These include Anegada, British Virgin Islands, a low coral atoll 11 miles long and 28 feet above sea level at its highest point. Passengers can spend a day at miles-long Cow Wreck Beach, a secluded, sandy spot with renowned snorkeling.

Terre-de-Haut, Iles des Saintes, provides a picturesque locale with views of sister island, Ilet a Cabrit, the main island of Guadeloupe and the volcanic La Soufriere mountain.

Located at the southern tip of the British Virgin Islands, Norman Island is an uninhabited, privately owned tropical paradise of 600 acres. A large harbor known as The Bight offers one of area's most protected spots. Passengers can hike, snorkel and scuba dive.

Union Island, the Grenadines, is nicknamed the ‘Tahiti of the West Indies’ due to its volcanic silhouette. Among the many restaurants and bars, Happy Island, a man-made island featuring a bar, sits in the middle of Clifton Harbor.

Another key feature of the Union Island region is Tobago Cays National Marine Park. The cays are a group of small, uninhabited islands surrounded by reefs, where SeaDream offers snorkeling, scuba diving and swimming.
