Experience the natural beauty and wildlife of the Everglades, as well as a forest of tropical trees at Collier-Seminole State Park. The 7,271-acre park lies partly within the great mangrove swamp of southern Florida, one of the largest mangrove swamps in the world. Collier-Seminole also contains one of the three original stands of the rare royal palm in Florida. The park is the site of a National Historic Mechanical Engineering Landmark, the last existing Bay City Walking Dredge. Built in 1924, it was used to build the Tamiami Trail Highway (U.S. 41) through the Everglades and Big Cypress Swamp, linking Tampa and Miami and opening southwest Florida to travelers. Visitors to Collier-Seminole have the opportunity to explore the park's wilderness in many ways, including hiking, bicycling or canoeing. Collier-Seminole provides canoe rentals, as well as a boat ramp with access to the Blackwater River, where anglers can fish for both saltwater and freshwater fishing. Collier-Seminole offers full-facility, primitive and youth camping. The picnic areas have pavilions and grills for use on a first-come, first-served basis.
