One of the lower Keys most original annual events is the Underwater Music Festival. Continental Americas only living coral reef is the site of the event, at which hundreds of divers and snorkelers explore the reef while symphonies are piped in from high quality underwater speakers. This years event will take place in the Looe Key section of the Florida Keys National Marine Sanctuary, six miles south of Big Pine Key, and run from 10 AM to 2 PM. Dozens of private boats will be attending, but also charters and tour boats are offering special trips to enjoy this original Keys experience. For more information click here.
