Chain O'Lakes State Park

8916 Wilmot Road, Spring Grove, IL 60081


The Chain O'Lakes in northwest Lake County is the busiest inland recreational waterway per acre in the United States.

Located in the northeastern corner of Illinois in both McHenry and Lake counties, the Chain O'Lakes State Park is 60 miles northwest of Chicago. With nearly 6,500 acres of water and 488 miles of shoreline on the Chain, Chain O'Lakes State Park is the heart of a water wonderland. And, with six miles of relatively easy hiking and biking trails to navigate the scenery, Chain O’Lakes State Park has become a treasure to behold.
