Join Arboretum art experts for a guided tour of the outdoor sculptures at the Arboretum on Thursdays and Saturdays throughout the summer! Choose from a Harrison Sculpture Garden Tour at 11:30 a.m. or visit sculptures around the Oswald Visitor Center at 1:30 p.m. The sculpture tours last one hour and provide visitors an understanding of the connection between art and nature and a deeper knowledge of the individual art pieces themselves.
