Biscayne National Park: Miami’s Underwater Backyard
Most national parks are known for mountains, canyons or forests you can drive through. Biscayne National Park is different. It sits just south of Miami, and most of it is water: a shallow bay, a chain of small islands and a living coral reef. If you live in South Florida, it is one of the most remarkable places within an easy drive, and many people have never been.
From Monument to National Park
In the 1960s, the bay and the keys south of Miami faced plans for development that would have changed the islands and the water. Local residents and conservationists pushed back, arguing that the clear water, reef and mangroves were worth protecting for everyone.
Their efforts paid off. In 1968 the area was protected as Biscayne National Monument. In 1980 it was expanded and became Biscayne National Park. Today it is one of the national parks in South Florida, along with the Everglades and Dry Tortugas, and it is the one closest to the city of Miami.
Four Worlds in One Park
Biscayne is often described as protecting several connected environments, each depending on the others:
- The mangrove shoreline. Along the mainland edge, mangrove trees grow right into the water. Their tangled roots shelter young fish and help protect the coast from waves and storms.
- Biscayne Bay. The bay is shallow and wide, with seagrass beds that feed and shelter many kinds of sea life. Manatees and sea turtles may be spotted in these waters.
- The keys. The park includes a string of small islands, the northernmost of the Florida Keys. Elliott Key is the largest, and Boca Chita Key, with its historic lighthouse, is the most visited.
- The coral reef. Farther offshore lies part of the Florida reef tract, where colorful reef fish, corals and sponges live in clear water.
Because these areas are linked, what happens on land and in the bay affects the reef, and the reef in turn protects the islands. Seeing all four in one trip helps you understand how fragile and connected coastal life is. Even a short boat ride from the mainland to the keys can take you through several of these worlds in a single morning.
History Under the Water
Biscayne is not only about nature. People have lived, worked and sailed here for a long time. The park protects traces of that history, including pioneer life on the islands. The Jones family, a Black pioneer family, farmed on the keys, and their former home area is now a historic district within the park.
Near the northern edge of the park stand the houses of Stiltsville, built on stilts above the shallow water starting in the 1930s. They are a well-known part of Miami lore.
Offshore, the reef has been dangerous for ships for centuries. The park's Maritime Heritage Trail is an underwater trail that lets snorkelers and divers visit the remains of shipwrecks from different eras. It is a rare chance to see history resting on the sea floor, slowly becoming part of the reef.
How to Visit
Since most of the park is water, the best way to explore is by boat. Here are some general tips for planning a visit:
Start at the visitor center. The Dante Fascell Visitor Center, near Homestead, is the main place to begin on land. It has exhibits about the park's ecosystems, and many boat tours and programs start there.
Book a tour if you do not have a boat. Guided boat, paddling and snorkeling trips are the easiest way to reach the keys and the reef. Check the park's official website for what is running when you plan to go.
Watch the weather. Wind and storms can change conditions on the bay quickly. Summer afternoons in South Florida often bring thunderstorms, so morning trips are usually a good idea.
Protect yourself and the reef. Bring water, a hat and sun protection, and never stand on or touch coral. Take your trash with you.
Respect wildlife. Give manatees, turtles and birds plenty of room, and keep boat speeds slow in shallow areas.
Why It Matters for Miami
Biscayne National Park is a reminder that the city's natural beauty is not only on its beaches. Just a short distance from busy highways and neighborhoods, a protected world of clear water, mangroves and reef carries on. It exists because people decided it was worth saving.
That is a good lesson for any of us. Some of the most valuable things in our lives are quiet and easy to overlook, and they last only if someone chooses to protect them.
Plan Your Day on the Water
If you have lived in South Florida for years and never visited, make this the season you go. Pack sunscreen, invite a friend and spend a day seeing Miami from the water. And if you want some music for the drive down, stream Jonathan Anthony Burkett, a Miami-born artist, on Spotify.
