Surrounded by the classic Kentuckian horses and distilleries, this extensive tract of forest is one of the few in the state that's really developed for easy visitor use. Starting in a valley, a road heads past a visitor center (which looked nice, but was only open for limited hours) and up a hill into thick forest. It's not always clear what places mean when they say "suggested donation", but upon entering here, they literally asked me if I would like to donate, and then how much, so for someone who is short on cash would like to enjoy the park, I don't think they'd stop you. Conversely, if you have a car full of kids, the $15 would be quite a good deal.
There were extensive paths in the lower portion of the park. You do have to put in some work to get to the various sculptures-including the forest giants-but this area is generally quite well manicured. The ponds were a bit scummy-which may be natural but isn't that visually appealing. Otherwise, the juxtaposition of various art objects on the natural surroundings was quite magical. Going up into the trees yields several trails and a walkway that leads one out into the treetops, where you get a distinctive experience and a cool breeze.
I gave it a couple of hours to explore and it would have been easy to spend most of the day driving from Louisville or Lexington. They're open until sunset or a bit after, but I did leave before that, mainly out of not wanting to drive in the dark.
