Biscayne National Park and the Reef You Don't Need a Plane For

Biscayne National Park and the Reef You Don't Need a Plane For

Biscayne National Park is 95% water, which makes it the most unusual national park in the system and the one most visitors have never heard of. It begins at the Dante Fascell Visitor Center in Homestead — thirty minutes south of Key Biscayne — and extends across Biscayne Bay to the northernmost coral reef in the United States, protecting 173,000 acres of mangrove shoreline, seagrass meadow, and living reef that connects the Keys to the mainland.

The snorkel trip to the reef is the park's signature experience — a boat ride to the offshore keys and a guided snorkel over brain coral, sea fans, and the neon-bright tropical fish that make Caribbean reefs look like someone shattered a stained-glass window underwater. The water is warm, the visibility is good on calm days, and the reef is close enough to shore that the trip takes half a day rather than a full one.

The paddle trail through the mangrove shoreline at the visitor center is the land-based alternative — a kayak route through channels so narrow the mangrove roots form a tunnel overhead and juvenile fish shelter in the root tangles with the urgency of creatures who understand the food chain intimately. Manatees frequent the shoreline in winter, and dolphins work the channel between the keys.

Practical notes: The visitor center is free. Snorkel and boat trips are run by concessioners and require reservation. Bring reef-safe sunscreen, water, and snorkel gear (rentals available). The park has no entrance fee — one of the few in the system — and the isolation of the reef means the snorkeling is better than anything you'll find at a resort beach.
