The trail system in Waterfall Glen Forest Preserve makes a loop around the entire park. The preserve is geologically significant, featuring glacier-carved rock ridges, ravines and wetland potholes, which are not found anywhere else in the county. The 700-acre forest is a contiguous wooded acreage interspersed with dolomite beneath a prairie habitat, home to rare plants.
As you explore the limestone-surfaced trail, you'll discover the woodlands with dominant oak and maple trees, as well as prairie and grassland habitats and planted pine groves. You're likely to see lots of wildlife here, too.
The multi-use trail system accommodates cyclists, equestrians and hikers, and some trails are groomed in winter for skiing. Cyclists must stick to the designated bike trails. Horseback riding is not allowed in developed recreational areas, such as the youth group campground.
Horseback riders can park their trailers in designated spots at the trailhead on Northgate Road; trailer parking is not allowed at the Lemont Road lot.
There are three main parking areas for Waterfall Glen Forest Preserve. On the north side, take I-55 to the Cass Avenue Exit and head south. Turn right on Northgate Road then right again into the parking area (there are 2 parking areas; the second right is a larger lot).
To access the southeast end of the trail continue south on Cass Avenue from I-55 and bear left at the elbow bend onto Bluff Road; the parking area is a short distance up the road on the right.
To access parking on the southwest side, follow Lemont Road to where it crosses 101st Street; the parking turnoff is on the east of Lemont where 101st comes in.
