Biscayne is the largest marine park in the U.S. National Park System—even camping requires a boat to get to the designated tent sites. The park offers canoe and kayak rentals year-round, and ranger-led boat tours between January and April.

Biscayne protects part of the world’s third-largest reef, which includes several threatened coral species. These sensitive marine animals are threatened by disease, climate change, and other dangers.

The green sea turtle is one of four endangered turtle species at Biscayne. Park officials monitor beaches during nesting season to protect eggs and hatchlings from predators.
