Devil's Millhopper Geological State Park

Devil's Millhopper is a geological state park built around a natural limestone sinkhole in Gainesville. The depression contains flowing water channels descending the limestone walls and a small forest environment at its base, reaching roughly 120 feet (37 meters) deep.

The site received National Natural Landmark designation in 1974, recognizing its geological significance for Florida's natural history. The rock layers hold fossilized shark teeth and shells from an ancient sea that once covered this region.

The name comes from animal bones discovered at the bottom and the funnel shape resembling a grain mill's hopper, connecting the place to the region's farming past. Visitors notice this local connection when walking through the area.

Visitors reach the sinkhole by descending 236 wooden steps and boardwalks that lead safely into the depression. Interpretive signs along the path explain the geological features and help you understand what you are seeing.

Three separate ecological zones exist within the park: sandhill forest, hammock woodland, and wetland area, each with its own plant life. This variety lets visitors experience multiple habitats during a single visit.
