This trio of islands has one thing in common: great diving. From wrecks to soft-coral covered piers and walls that plunge into the abyss, there are scores of sites to fill any number of dive vacations. Otherwise, each island has its own distinctive qualities: St. Thomas has its shopping and beaches, St. Croix has its laid-back attitude and rugged beauty, and quaint St. John has its artistic eco-environment. A ferry connects the islands of St. Thomas and St. John while St. Croix is a short 25-minute flight away. Topside adventures include sailing, snorkeling, scenic tours by foot, horseback, mountain bike or car, sugar plantation tours and mangrove kayaking.
