The park has 5 miles of well-marked, well-surfaced hiking trails for a relaxing walk or a vigorous hike. Large trail maps are located at all major trail intersections so visitors can choose a variety of routes. The upper area and bluff tops are easy hiking paths for the novice, but the trails into the interiors of the two dells may be difficult to negotiate, particularly during spring and early summer. Hikers must stay on marked trails, as steep cliffs and deep canyons can be dangerous. Hikers will marvel at the plant and animal life along the trails, and have an unparalleled view of geological wonders as they travel through the park. Alcohol is prohibited on all trails.
Off of Interstate 80 take Exit 81, Rt. 178 to Utica, IL then five miles south on Rt 178.
