Opus 40
Located in the Catskills foothills between Saugerties and Woodstock, NY is a fantastic outdoor sculpture park created, primarily, by one Harvey Fite, who was an art professor at Bard College.
He spent just shy of 40 years turning a bluestone quarry into a beautiful landscape of carvings, ramps, walls and pools. There are a small museum of quarrying tools and a handful of picnic tables, all with a view of Overlook Mountain.
