If exploring below the waves is on your Barbados bucket list, the Atlantis Submarine will oblige with an undersea voyage like none other. The 48-passenger submarine is the real deal with windows on all sides for views of the coral reefs, colorful fish, and shipwrecks that lie 150 feet below the surface of the Caribbean Sea. Tours are family friendly and also offered at night when the lights beaming from the submarine illuminate the marine predators and reef fish that play after dark. Sunset, meanwhile, is a chance to watch schools of fish scoot past the windows during feeding time. Tip: prime seating is directly behind the pilot and his large viewport.
