Curry Hammock State Park in Marathon, Florida, represents the largest undeveloped natural preserve between Key Largo and Big Pine Key along the Overseas Highway. This pristine coastal destination offers RV camping with comprehensive facilities including water and electrical hookups (30 and 50 amp service), shower stations, dump stations, and full restroom facilities—ideal for extended stays. The park's defining characteristic is its unspoiled natural environment, protecting vital ecosystems including mangrove swamps, rockland hammocks, and seagrass beds. A 1.5-mile nature trail winds through hardwood hammock, providing immersive exploration of the Keys' unique habitats. Beach access and dedicated kayak and canoe launches serve paddlers and water enthusiasts. Activities range from kayaking and snorkeling to fishing, bicycling, hiking, and wildlife viewing. Visitors frequently encounter dolphins, manatees, and horseshoe crabs, while autumn brings record numbers of migratory peregrine falcons. Pet-friendly amenities, picnic pavilions, grills, tables, and a playground make it accessible for families. The park functions as part of the Florida Circumnavigational Saltwater Paddling Trail system, attracting both day-use visitors and campers seeking authentic wilderness experiences along the Florida Keys.
