The Crystal Bridges Museum of American Art is located in Bentonville in northwest Arkansas on 120 wooded acres of land that was the home of Sam Walton. The museum building crosses a stream and lake, with part of the buildings "bridging" the crystal clear waters.
Parking and admission is free. The grounds are lovely, and were in full autumn color when we were there in early November.
