Natural History Bike Tour


A bike wheel against a background of green trees

Discover the natural history of northeast Illinois as we cycle the roads of the Arboretum. The Arboretum contains wonderful examples of the region’s wetland, prairie, and woodland ecosystems. Learn about the characteristics of these natural areas that define northeast Illinois. Find out about the fascinating geology that characterizes the landscape, including the glacial moraines that are responsible for the hilly terrain at the Arboretum.

This program coincides with Vehicle-Free Hours at the Arboretum, so participants can peddle the peaceful roads without concern of car traffic.

Notes: Ages 16+. Bring your own bike. Helmets required. Must be comfortable riding at a leisurely pace approximately 8 to 9 miles over rolling terrain. In case of inclement weather, the rain date will be July 20 or August 3. Limit 15
