The 2,400-square-mile Big Cypress National Preserve, part of Big Cypress Swamp, is a delicate ecological habitat and wildlife refuge. Connect with nature in the unspoiled environment on a trail walk or airboat ride just off of US 41. Keep a keen eye on the water’s surface for a peek at alligators or turtles. Watch for egrets and herons wading through the marshlands.
