A short drive from the center of Marianna, a cute and pristine community, you can see what's behind or—more accurately—what's beneath it all. Ranger-led cave tours reveal stalactites, stalagmites, soda straws, columns, rim stones, flowstones, and "waterfalls" of solid rock at these underground caverns, where the temperature hovers at an oh-so-pleasant 68°F year-round. Some of the caverns are off-limits to the public or open for scientific study by permit only, but you can still see enough to fill a half-day or more—and be amazed that caverns of this magnitude exist in the Sunshine State. Don't forsake the quiet, preserved, and peaceful woodlands, which encompass 10 distinct communities including upland glade, hardwood forests, floodplains, forests, and swamps. There are also hiking trails, campsites, and areas for swimming, horseback riding, and canoeing on the Chipola River.
