This perfect Caribbean island offers divers (and non-divers) a blissful vacation, above and below the waves. For divers, this island is paradise — Anguilla's turquoise waters boast seven marine parks, Dog Island, Prickley Pear, Seal Island Reef System, Little Bay, Sandy Island, Shoal Bay Harbour Reef System and Stoney Bay Marine Park. It's time to giant-stride in!
