Tobico Marsh: a Great Lakes wetland behind the beach

Bay City State Park is easy to mistake for just a beach and campground. The Michigan DNR says the park has more than 1,000 feet of sandy Saginaw Bay beach, but it also protects more than 2,000 acres of wetlands, woods, and prairie. Behind the beach is Tobico Marsh. DNR calls it one of the largest remaining freshwater coastal wetlands on the Great Lakes, and the visitor center identifies it as a National Natural Landmark.

The marsh is an important resting and feeding area for migratory birds, especially during spring and fall. You do not need a species checklist to enjoy it. Two observation towers, a boardwalk, viewing platforms, and shoreline spotting scopes give you several ways to look over the wetland. Shorebirds, herons, and nesting songbirds are among the groups DNR highlights.

For a low-friction visit, begin at the Saginaw Bay Visitor Center near the park entrance. Its exhibits explain the marsh, and staff can point you toward current trail conditions and programs. Then choose the beach, the wetland trails, or both. The DNR park page has the live map, amenities, events, and any current notices.
