Fayette State Park is near Manistique and is interesting from a historical/tourist point of view. And if you are coming all this way you should visit the Pictured Rocks National Lakeshore between Munising and Grand Marais, which are both nice little towns to visit as well. There are a number of very nice waterfalls in the Munising area, including Munising, Wagner, Miner's and Sable Falls. The Seney National Wildlife Refuge is pretty interesting; there is a nature trail that you can drive through the refuge to see the various flora and fauna. The Lake Michigan beaches along US 2 as you head towards St. Ignace. Mackinac Island is the usual tourist destination. All of these places are worth the visit from a tourist perspective, but all provide nice photographic opportunities as well.
