Have You Discovered Waterfall Glen?


Hikers, runners, and bikers will want to consider visiting DuPage County’s Waterfall Glen Forest Preserve. This gorgeous setting is a great choice for a day spent outdoors exploring the site’s extensive trail system, vibrant habitats, and most of all, scenic views. Waterfall Glen is a short trip from downtown Chicago and a family-friendly destination in suburban Darien.

Waterfall Glen is managed by the Forest Preserve District of DuPage County and open to the public year-round. The site is home to a 9.5-mile gravel trail system that winds through a hilly, wooded landscape, offering educational signage and opportunities to explore nature up close. If you’re not looking for a nearly 10-mile trip, however, don’t let the longer trail intimidate you. Waterfall Glen not only offers shorter trails throughout the preserve, but you can also make a nice trip out of the short walk from a parking area to two of the site’s most scenic areas, Rocky Glen Waterfall (pictured above) and Sawcreek Mill Bluff.

The main trail at Waterfall Glen is an approachable 9.5-mile gravel path and makes for a great workout whether you’re hiking, biking, walking, or trail-running. The main trail is mixed-use for pedestrians, bikes, and horseback riding, so be sure to share the path. The trails are also open in the winter for snowshoeing, walking, and cross-country skiing. 

For the site’s natural beauty and recreation opportunities, Waterfall Glen is well worth your visit! Consider adding it to your trip this summer or check out all our recommendations for where to get outside in the region.
