Highlands Hammock State Park is a park west of Sebring in Highlands County, Florida, off U.S. 27. The park opened in 1931, four years before the Florida state park system was created. It was listed on the National Register of Historic Places in 2018. Ecology Flora Elevated boardwalks meander through an old-growth bald cypress swamp with cabbage palmettos, ferns, bromeliads, orchids and other epiphytes. Some trees are believed to be over a thousand years old, and one is possibly the largest oak in Florida, with a girth of over . Fauna White-tailed deer, American alligators, gopher tortoises, frogs, otters, golden silk spiders, pileated woodpeckers, red-shouldered hawks, barred owls and Florida scrub jays are common in the park. Florida black bears, bald eagles, white ibis, gray squirrels, bobcats and the rare Florida panther are seen on occasion. History Local citizens, concerned about plans to turn the hammock into farmland, acquired the property in 1931 and promoted it as a candidate for national park status, an early example of grass-roots public support for environmental preservation. One of the prime movers behind the effort was Mrs. Margaret Roebling, daughter-in-law of Washington Augustus Roebling. Though it never reached national park status, it became one of the four original Florida State Parks when the state park system was created in 1935. The Civilian Conservation Corps (CCC), established during the Great Depression, built a camp at Highlands Hammock as a headquarters, and developed additional park facilities and the beginnings of a botanical garden. Florida Civilian Conservation Corps Museum The park features the Florida Civilian Conservation Corps Museum with interactive exhibits about the 1930-1940s period of the park's construction, and the history of the CCC in Florida and the United States. The museum is located in a building constructed by the CCC. Recreational activities The park includes a scenic three-mile (5 km) loop drive that gives access to the park's nine trails, and can be used for inline skating. An eleven-mile (18 km) trail can be traversed by bicyclists, horseback riders or wildlife viewers. Birding may also be done, since the park is part of the Great Florida Birding Trail. Ranger-guided tours are scheduled frequently. There is a campground with full hookups, and areas for full, primitive, and youth camping. A picnicking area is available with an adjacent playground and fun , as well as a restaurant, called "The Hammock Inn". During the fall and winter season
