Theater of the Sea is the snazziest marine attraction in the Forida Keys. There are nonstop performances every day from 9:30am to 4pm, and there is an extensive Swim with the Dolphins program with several levels of participation depending on what you are up for. Children can become Trainer for a Day and help trainers feed and tend the dolphins. There are also the Swim with the Sea Lions and Swim with the Stingrays programs, both of which may include the occasional sea turtle swim-by bonus. If you don't want to swim with anything, the basic facility is also fascinating, consisting of several lagoon pools created when the Flagler railroad was being built in the first half of the 20th century. They've got sharks, dolphins, stingrays, game fish, and a whole world of marine life in there. Performances involve these lagoons and marine life. Call for current rates. Don't miss the bevy of stray cats who rule the parking lot...don't worry they won't harm you, or even notice you.
