The Lower Peninsula's biggest state park is near Chelsea

The biggest state park in Michigan’s Lower Peninsula is not up north. Waterloo Recreation Area covers more than 20,000 acres in Jackson and Washtenaw counties. It sits between Jackson and Ann Arbor. Glaciers shaped its rolling woods, wetlands, kettle lakes, and ridges. Even a short walk can feel less flat than the map suggests.

The DNR lists 11 inland lakes. Visitors can camp, fish, hunt, swim, hike, bike, or ride horses in different parts of the park. The Waterloo-Pinckney Trail reaches east toward Pinckney Recreation Area. Other routes serve day hikers and winter visitors. A Recreation Passport is required for vehicle entry.

Waterloo has several entrances, and choosing the right one matters. The Gerald E. Eddy Discovery Center near Chelsea is a good first stop. Its exhibits explain the park’s geology and wildlife, and trails begin nearby. Campgrounds, beaches, and longer trails use other approaches. The DNR map will point you to the right one.
