The Betty Hauptli Bird and Butterfly Garden, native prairies, woodland flower gardens, hiking trails and historic Junkermann farm site are just some of the many attractions at the Center. The E.B.

There are five individual nature walks within the park, including those at the E.B. Lyons Interpretive Center and another at the Horseshoe Bluff Site.
