Devil's Millhopper Geological State Park

Steve’s take

A giant sinkhole with a rainforest at the bottom. In Gainesville. I know — Florida is weird. You walk down 232 steps into what feels like Jurassic Park, see waterfalls and ferns that shouldn't exist this far north, and then walk back up those 232 steps, which is when you remember you are not in the shape you were in college. The kids love it. Your quads will have opinions.
