W.J. Hayes State Park, in the heart of the Irish Hills, is bordered by a group of inland lakes frequented by anglers and boaters. The park's close proximity to Michigan International Speedway, crafts and antique shows and other attractions make Hayes State Park a prime tourist destination. The park is also newly handicapped accessible.

Hayes State Park is one of the system's oldest state parks. Dedicated in 1920, the park originally was named Cedar Hill State Park. The name changed when the Hayes family donated land to the park with the condition that it be renamed to honor Walter J. Hayes, a Michigan senator. The park has gone through many changes, but the major constant has been the attraction of Michigan's visitors to the recreational waters of Wamplers Lake.
