Hayes State Park, in the heart of the Irish Hills, is located on Wamplers Lake and Round Lake great for fishing and boating. The park's close proximity to Michigan International Speedway, crafts and antique shows and Hidden Lake Gardens make Hayes State Park a prime tourist destination.
History of the Area
Hayes State Park is one of the system's oldest state parks. Dedicated in 1920's, 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.
The Recreation Passport is required for vehicle entry into state parks and recreation areas, state boat launches, state forest campgrounds and state trail parking lots. Details and information on how to obtain your Michigan Recreation Passport can be found by visiting the MICHIGAN RECREATION PASSPORT web page.
