32 Offbeat Cruise Excursions That Go Way Beyond Sightseeing

15. Take a Submarine Ride to an Underwater Shipwreck in Barbados

While many Caribbean cruise excursions focus on snorkeling or scuba diving, Barbados offers a rare chance to explore the deep sea in a real submarine. The Atlantis Submarine Tour takes you 150 feet below the ocean’s surface, where you’ll glide past coral reefs, schools of tropical fish, and even a sunken shipwreck. No diving gear required—just sit back and enjoy the thrill of being inside a real underwater vessel. Pro Tip: For the clearest views, book a morning tour before the sand and sea life get stirred up by other activities.
