The Lower Peninsula's biggest park is in Washtenaw's backyard

The biggest state park in Michigan’s Lower Peninsula isn’t up north — it’s twenty minutes west of Ann Arbor. Waterloo Recreation Area sprawls across roughly 20,000 acres of glacial hill country on the Washtenaw–Jackson line: a dozen lakes, hardwood ridges, marshes and fens, campgrounds, equestrian trails, and the trailhead of the Waterloo–Pinckney Trail, a 35-mile backpacking route that lets southeast Michiganders train for the mountains without leaving home. The Gerald Eddy Discovery Center anchors it with year-round nature programming on a glacial kettle lake.

For the small towns and townships of western Washtenaw — Chelsea, Manchester, Dexter, and the farm townships between — Waterloo functions as a shared backyard wilderness, with the adjoining Pinckney Recreation Area and Park Lyndon stretching the green even further. It’s the rare metro-edge geography where the question isn’t whether there’s a trail nearby, but which of the hundred miles you feel like today.
