Collier–Seminole State Park in southwest Florida spans 6,430 acres of mangrove and cypress swamps, salt marsh, river estuaries, and pine flatwoods south of Naples on U.S. 41. It is especially significant for preserving the Bay City Walking Dredge, the machine used in building the Tamiami Trail through the Everglades and helping connect south Florida by road, an important achievement in regional engineering history. The park also supports abundant wildlife, including alligators, ospreys, white ibis, crocodiles, black bears, and wood storks. In addition to its natural and historic value, it offers trails, canoeing, camping, boating, fishing, and wildlife viewing year-round.
