Apple River Canyon State Park

This National Park is situated near the Wisconsin border in the hilly northwest part of Illinois. This scenic canyon area was formed by the action of the winding waters of Apple River. Limestone bluffs, deep ravines, springs, streams, and wildlife characterize this area which was once a part of a vast sea bottom that stretched from the Alleghenies to the Rockies.
The park offers hiking, day use, camping, and fishing in hilly northern Illinois, plus Millville, a National Historic Register site.
