Hillsborough River State Park is one of Florida's first state parks, established in 1938 by the Civilian Conservation Corps. The park is defined by the Class II river rapids on the Hillsborough River, a rare geographic feature in the Florida landscape. It encompasses over 3,000 acres of diverse ecosystems, including river swamps, oak hammocks, and pine flatwoods. Visitors engage in kayaking and canoeing along a designated seven-mile segment of the river. The site features an extensive trail system covering over seven miles, including the River Rapids Nature Trail. Wildlife sightings commonly include alligators, river otters, turtles, and various bird species. Fishing is permitted in the river, provided visitors adhere to state freshwater regulations. The park contains a historic cafe building and original CCC-constructed amenities.
