Most of Biscayne National Park can only be seen by boat, but the exception is the Jetty Trail near the visitor center. This coastal boardwalk provides views of mangrove trees and shellfish communities at the water’s edge. Look over the ocean to see many kinds of birds, and perhaps even fish or dolphins. Whether or not you board a vessel to explore more of the park, you can enjoy a glimpse of Biscayne’s natural environment here.

Boca Chita is the most-visited island in Biscayne National Park, thanks to its calm harbor, sand beaches, and a picturesque lighthouse. On this key is also a short trail that loops around the island. The sandy path goes among scattered palm trees and leafy forest to find secluded clearings overlooking the water.

Elliott Key is by far the largest island in Biscayne National Park, but most visitors only spend time in its small marina and campground. If you want to explore more, however, there are a few options for hiking trails. One is a short loop that finds a small, secluded beach on the ocean side of the key. The other is a much longer path called the Spite Highway, which delves into the thick forest of the island's interior.
