2. St. Croix
The largest member of the U.S. Virgin Islands, Danish-influenced St. Croix is recognized as a top diving destination in the Caribbean. St. Croix offers scuba fans a number of diving options including beach dives, reef dives, wreck dives, night dives and wall dives. Scuba divers enjoy discovering the underwater trails of the national park at Buck Island, just off St. Croix’s mainland. Don’t miss the coral canyons at Cane Bay, Salt River or Davis Bay. From here you can enjoy exploring the 3,600m-deep Puerto Rico Trench, the fifth-deepest body of water on earth.
