The Miami area has two National Parks: Everglades and Biscayne National Park. The Everglades were amazing, so we wanted to check out Biscayne as well. Biscayne National Park is 95% water, with only one trail at the Visitor Center. There was parking at the Visitor Center and you could schedule a boat to take you around the park.
The Visitor Center had a movie about the park, as well as a great learning area about the history of the area and it’s ecosystem. We all learned that the red mangroves are the ones you normally think of with their long roots reaching into the water. The black mangrove trees have roots that stick up through the ground like straws! The Visitor Center’s trail was only about a 1/4 mile. The path consists of a bridge and a dirt path, but we did get to see the different types of mangroves in person along the trail. Nick was able to complete the Junior Ranger program there as well, as this book was mostly reading and could be done without taking a boat into the Park.
Guided tours (via boat, snorkel, paddle boards, and kayak) are available, but do cost extra. It was neat to see, but not very much to do unless you take a boat out.
