The Fox River Trail is one of the premier multi-use trails in northeastern Illinois, and Crystal Lake-area residents have easy access to it through Cary and Algonquin. The paved trail follows the Fox River valley, offering miles of scenic biking, running, and walking through forest preserves, small downtowns, and riverfront parks.
