Biscayne National Park Boat Tour

Biscayne National Park protects 172,971 acres, and roughly ninety-five percent of that acreage lies underwater. Only a thin five percent stands above the tideline, which is why a biscayne national park boat tour functions as basic access rather than an upgrade. Congress set the place aside as a national monument in 1968, enlarged it and redesignated it a national park in 1980, and no road has ever crossed it. Park headquarters sit at Convoy Point in Homestead, facing open water instead of a trailhead. Four ecosystems press against one another within a few nautical miles: a mangrove shoreline, the shallow bay, a chain of coral-limestone keys, and the northern end of the Florida Reef. Seagrass flats glow pale green beneath passing hulls. Manatees graze them, American crocodiles hold the brackish creeks, and spiny lobster shelter under ledges offshore. The logistics follow from the geography, and every biscayne national park boat tour tour is shaped by it, since the islands cannot be reached on foot. Boca Chita Key carries a 65-foot ornamental lighthouse raised in the 1930s by the industrialist Mark Honeywell, who kept the island as a private retreat. Elliott Key, the largest at about seven miles long, holds the last substantial tract of tropical hardwood hammock in the upper Keys; Hurricane Andrew flattened much of its canopy in 1992, and it has grown back dense and low. Porgy Key belonged to Sir Lancelot Jones, born 1898, a Black sponger and bonefishing guide whose refusal to sell to developers helped make the park possible, and the access road at Convoy Point now bears his name. Biscayne National Park Boat Tour tours and Miami skyline cruises both run within sight of Stiltsville, the handful of stilt houses still standing on the Safety Valve flats. Six wrecks, among them the steel schooner Mandalay lost in 1966, form the Maritime Heritage Trail. Pressure on this park has always arrived by hull. A 1960s plan would have dredged a deepwater seaport and set an oil refinery on the shoreline; the counter-campaign produced the monument instead. Those vessels decide who drifts through Jones Lagoon and who watches frigatebirds from the seawall.
