Waterfall Glen

Waterfall Glen is a crushed-limestone loop surrounding Argonne National Laboratory and is a favorite among local riders, though it's often overlooked by visitors. While the loop itself isn't especially long, connecting Waterfall Glen with the I&M Canal Trail, nearby quiet roads, and short stretches of the Palos trail system can create an incredibly varied ride. Within a small radius riders can piece together scenic gravel, pavement, and singletrack for surprisingly big mileage and exploration.
