A short nature trail, a 232-step stairway and multiple boardwalks allow you to bird the slopes of a massive sinkhole 120 feet deep and 500 feet across. The lush hardwood slope forest and tranquil springs are good for skulking songbirds like the Veery, Wood Thrush and Eastern Towhee. Brown Creeper and Fox Sparrow (both rare) have been found here occasionally in winter. Pine flatwoods, sandhills and upland mixed forest are also present in this park. Breeding birds include Summer Tanager, Great Crested Flycatcher, Tufted Titmouse and Pileated Woodpecker. Other possibilities include Eastern Screech-Owl, Least Flycatcher, White-eyed Vireo, American Woodcock and 30 species of wood-warbler during migration. Sightings of Bobcat, Northern Raccoon and Gray Fox are possible; also watch for Florida Box Turtle, Gray Treefrog and Southern Dusky Salamander. Butterfly viewers have several rare species to look for at this park such as Golden-banded Skipper, Harvester and Little Glassywing. Devil’s Millhopper is a registered National Natural Landmark.
