Biscayne National Park is one of the best keep secrets down here in south Florida. The concession that is running the snorkel and dive boats are doing a great job in opening up the park and its wrecks and reefs to the public. We do have dive trips on the weekends and can do charters during the week and also one tank dives that go out with our regular snorkel trips. For dive trips the boat leaves at 8:00 AM and on our daily snorkel trips the boat leave at 10:00 AM and at 1:30 PM.
