Port Huron Michigan, located on Michigan's Thumb Coast at the very point where the Saint Clair River meets Lake Huron, is definitely worth a visit. In addition to the beautiful views on the Blue Water Bridge, Michigan's heavily-traveled international bridge to Canada, you'll find a lot to do here. Lighthouse Park is located on a wide expanse of Lake Huron shoreline, perfect for swimming and hunting for Michigan Petoskey Stones. Historic Fort Gratiot Light, Michigan's oldest ighthouse, is located here, too, and open for tours.
