Sculpture Park would be a more accurate term but even that is misleading. Going here by on your own (e.g. not part of a guided tour) is not recommended. The pieces have a raw, unfinished quality to them. Also although its on the grounds of the hotel, you go right up the front porch of some individual cabins, I felt kind of weird just showing up and hanging out to look at the sculpture.
Thought provoking, interesting, and a pleasant surprise while staying at the Wilburton Inn.
