Located in the heart of Illinois' largest concentration of natural lakes, Chain O Lakes State Park is a water oriented recreation area with outstanding opportunities for boaters, anglers and skiers. The park borders three natural lakes - Grass, Marie and Nippersink - and the Fox River that connects the other seven lakes (Bluff, Fox, Pistakee, Channel, Petite, Catherine and Redhead) that make up the Chain. In addition, the park contains a 44-acre lake within its boundaries.

The 2,793 acre state park and adjoining 3,230 acre conservation area are located in the northeastern corner of Illinois in both McHenry and Lake counties. About 80 acres within the park have been set aside as a nature preserve to protect a segment of the park's bog environment and the unique plants associated with the area. With nearly 6,500 acres of water and 488 miles of shoreline on the chain, Chain O Lakes State Park is the heart of water wonderland.
