In spring and summer, 7 acres of lush blossoms and greenery abound at this oasis of nature at University Circle. Year-round, visitors are drawn to the tropical ecosystems housed in the stunning new Eleanor Armstrong Smith Glasshouse and Environmental Education Center. The crystal-like conservatory is home to hundreds of species of butterflies, birds, animals, and plant life of both Madagascar and a Costa Rican cloud forest. Although the Hershey Children's Garden closes for the winter on November 1, all other gardens remain open year-round.
