Biscayne National Underwater Park

Nearly all of this park’s 181,500 acres are underwater, so come prepared to explore via glass-bottomed boat tours, canoe or—better yet—snorkelling or scuba diving. Get an introduction to the park’s ecosystems and wildlife at the visitors’ center, built in the style of the area’s pioneer homes. Of interest are the ecologically important mangrove forest, the abundant birdlife and, of course, the dazzling coral reef filled with brilliantly colored fish, sea turtles and other marine life. Wildlife-lovers should take a boat trip to the neighboring keys, full of nesting birds, subtropical forests and nature trails. Note that due to damage caused to the dock by Hurricane Sandy, boat tours had been temporarily suspended at time of writing; call to confirm schedule before visiting.
