Your Key West snorkel adventure starts on a catamaran. A Key West snorkel adventure includes sailing on the only live coral reef in the U.S., professional instruction, sanitized dive gear, fresh water shower, free soft drinks, beer, and wine and easy access to the water via the sea ramp. There's so much to do, so we developed this site in order to help our visitors do as much of the planning as possible online and be sure to book a great Key West snorkel adventure.
