There are a lot of CG's in the Straits area. A couple dozen or more south of the bridge and about a dozen more north of the bridge! However, Mill Creek is about the best on the south side of the bridge as it's close to so many things and it's on the lake with a long sand beach and sand bottom. Wilderness State Park CG is very nice also but it's about 10.5 miles west of Mackinaw City. Straits State Park north of the bridge in St Ignace is very nice also but the beach and bottom is very rocky. It has very nice views 24/7.
