About Algonac State Park
Algonac State Park covers 1,550 acres along the St. Clair River between Marine City and Clay Township, and it's best known for one thing above all else: freighter watching. Freighters and ore boats pass close to shore on their way between Lake Huron and Lake Erie, and the park's half-mile of riverfront makes for one of the most reliable freighter-spotting locations in Michigan.
Two modern campgrounds — the Wagon Wheel (76 sites) and Riverfront (220 sites) — offer electric hookups, with full-hookup and 50-amp service available in the north section. Winter camping is permitted, and a group-use site is available for larger gatherings.

Things to Do
Beyond freighter watching, Algonac protects more than 1,200 acres of dedicated natural area — prairie, savanna, and wetland habitat supporting 22 threatened, endangered, or special-concern species, a rarity this close to metro Detroit. The 54-mile Bridge to Bay Trail runs through the park for hiking, running, and biking, and there's a shooting range on-site for archery, hand-trap, and rifle/handgun use. A boat launch serves kayaks, canoes, and paddleboards heading out onto the river.
Best Time to Visit
Spring and fall are prime for wildflowers in the prairie and savanna areas and for freighter traffic, while summer brings warm river access and the park's seasonal nature programs. Year-round camping means it's also a viable winter destination.
Reservation Tips
Algonac is well below the radar compared to Michigan's bigger-name parks, so reservations are typically easier to land — but summer weekends near the river bluff still go first. Book through MiDNRReservations.com within the 6-month window for your preferred loop.
Getting There
The park is about an hour northeast of Detroit via I-94 and M-29, tucked along the St. Clair River across from Canada — a scenic drive along the water most of the way.
