Biscayne National Park

Stand at the edge of the water here and listen. Small waves slap against the rocks of the jetty. A pelican drops into the bay with a hard splash. The air is warm and heavy with salt, and the smell of mangrove mud drifts in from the shoreline. Look out across the water. It is pale green near your feet, then turquoise, then a deep blue at the horizon. That colour change is the first lesson of this place. Almost everything worth seeing here is under the surface.

Welcome to Biscayne National Park, on the southeast coast of Florida, just south of Miami. Most national parks are measured in mountains, forests, or canyons. This one is measured in water. Roughly ninety-five percent of the park is bay, ocean, and reef. The land you are standing on is only a thin frame. Rangers like to say that visitors arrive and ask where the park is. The honest answer is simple... you are looking at it.

The park protects four connected worlds, and they sit in a line from the shore out to sea. First comes the mangrove forest along the mainland coast. Then comes Biscayne Bay itself, a shallow lagoon with seagrass beds on the bottom. Next is a chain of low islands, the northernmost of the Florida Keys. Finally, beyond those islands, the coral reef begins. Each world depends on the others. Fish that live on the reef as adults often grow up in the shelter of the mangroves and the grass.

Look at the mangroves near the shoreline. Their roots arch out of the water like the legs of a table. These trees can live in salt water, which most plants cannot do. The tangled roots slow the waves, hold the mud in place, and give small fish a place to hide from predators. During hurricanes, this green wall takes the first blow and helps protect the land behind it. It is not a pretty postcard view. But without it, much of the life in this park would not exist.

Now look past the bay toward the low dark line of the islands. The largest of them is Elliott Key. In the 1960s, these islands came very close to becoming a city. Developers and some landowners pushed a plan to build homes, hotels, and a causeway across the bay. Supporters even had a name for their proposed city — Islandia. To strengthen their case, a group of landowners cut a wide road down the length of Elliott Key with bulldozers. Locals later called it the Spite Highway.

The plan did not succeed. Conservationists, fishermen, and local politicians fought to protect the bay. In 1968, the United States government declared the area a national monument. In 1980, it was expanded and became a national park. Today, the old bulldozed road on Elliott Key is a quiet trail through the forest. It is a strange thing to walk on. A road built to bring a city is now a path through the trees, used by hikers, lizards, and butterflies.

Here is a story that many visitors miss. Long before the developers arrived, a Black family farmed these islands. Israel Lafayette Jones came to South Florida in the late nineteenth century. He and his family bought land on Porgy Key and grew pineapples and key limes. His sons, Lancelot and Arthur, later became well known as fishing guides. Wealthy visitors came to fish with them, and the family stayed on the islands for decades. Lancelot Jones refused to sell to the developers. Eventually he sold his land to the park, so it would be protected.

Further north in the park, there is another unusual human story. A small group of wooden houses stands on stilts in the open water, far from shore. This is Stiltsville. In the early and middle twentieth century, people built these structures as fishing camps and private clubs. Some were known for parties, and some for quiet weekends on the water. Storms destroyed many of them over the years. Only a handful remain today. From the right boat, they look like a village that walked out into the sea and stayed there.

On a small island called Boca Chita Key, you will find a lighthouse. Here is the surprise — it was never a working navigation light. In the 1930s, a wealthy businessman named Mark Honeywell owned the island and built the tower as a decoration for his private retreat. It is made of coral rock, the same pale, pitted stone you see along the shoreline here. Today, boats tie up in the small harbour, and people picnic on the lawn below the tower. It is one of the most visited spots in the whole park.

Beyond the islands lies the reef, and beyond the reef lies a graveyard of ships. This stretch of shallow, rocky water has wrecked vessels for centuries. Sailors could not always see the reef until it was too late. The park now has a Maritime Heritage Trail, a set of shipwreck sites that snorkelers and divers can visit. Some wrecks are only a few metres down. Divers can still see iron hulls, boilers, and anchors covered in coral and sponges, with fish moving in and out.

The reef itself is part of the Florida Reef Tract. This is the only living coral barrier reef in the continental United States. Corals are tiny animals that build hard skeletons, and over thousands of years those skeletons form the reef. The reef here faces serious pressure from warming water, disease, and pollution. Scientists and volunteers work to grow young corals and replant them. On a calm day, snorkelers see parrotfish, angelfish, sea fans, and sometimes a sea turtle gliding past.

Keep watching the bay itself, even from shore. The water is shallow, and the seagrass beds on the bottom feed a surprising number of animals. Manatees sometimes move slowly through these waters, rising to breathe with a soft puff of air. Dolphins pass through. Wading birds stand in the shallows and wait for fish. On a clear day, you can also see the towers of the Miami skyline to the north. It is a striking reminder of how close this wild water lies to a major city.

Before you leave, take one more look from the end of the jetty. Notice how flat and calm the bay seems, and how much is hidden beneath that calm surface. Notice the wind in the mangrove leaves and the pelicans resting on the posts. Many people drive past this coast without stopping, because they see only water. You now know what is out there... islands with family stories, houses on stilts, a lighthouse that never guided a ship, and a living reef. As you walk back, listen to the water once more.
