Some of the most beautiful blooms are found on red buckeye shrubs in April and wild lotus in June. Native southern hardwood forests are abundant, and two large, undisturbed tracts have been dedicated as Illinois Nature Preserves. These preserves are open to visitors, but are also used for scientific research and education. Each site includes picnic tables, park stoves and parking. Visitors with children might appreciate the playground located at the picnic area near the spillway.
Drinking water is available at hydrants and fountains conveniently located throughout the park.
While groups of 25 or more are welcome and encouraged to use the park's facilities, they are required to register in advance with the site office to avoid crowding or scheduling conflicts. At least one responsible adult must accompany each group of 15 minors. Pets must be kept on leashes at all times. Actions by nature can result in closed roads and other facilities. Please call ahead to the park office before you make your trip.
