Key West is home to the only living coral reef in the continental U.S. There are many snorkeling excursions to choose from, but the Snorkel and Champagne Sunset Cruise is truly unique. The catamaran brings passengers to the best locations to dive in and experience marine life up close. Don’t worry if you’ve never snorkeled before—the staff offers professional instruction. When reef exploration is over, grab a drink and relax on deck. The sunset views from Key West’s harbor are fantastic. You can also watch the Sunset Celebration at Mallory Square, away from all the hustle and bustle.
