Florida Caverns State Park is located at 3345 Caverns Rd, Marianna, FL 32446. This park features hiking but also ranger guided cavern tours that last about 45 minutes and take you through various connected caverns in the park.
FYI: Since Hurricane Michael struck the park in 2018 it has been slow to bounce back. When I last checked cavern tours were open, but other things such as hiking were still NOT an option as of 2020.
