The EB Lyons Interpretive Center serves as a visitor information center and park office. Displays and exhibits provide information about the history and features of the park. 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 EB Lyons Interpretive Center is open year-round. During the summer season, special programs can be scheduled with our naturalists.
