Hop aboard a double-decker glass-bottom boat that lets you view coral reefs, sea turtles and an 18th-century shipwreck. Bermuda Reef Explorer offers two-hour tours of these underwater sights as well as three-hour snorkelling cruises to a secluded cove, with snorkel gear provided. Nighttime Pirate Adventure cruises illuminate the sea bottom for a rare glimpse of Atlantic sea life and ship wreckage, along with stories from Captain Michael Gladwin about Bermuda’s buccaneering past. Tours depart from the Island Tour Centre in Hamilton.
