Bay City State Park is located on the shores of Saginaw Bay, Lake Huron, and features over 1,000 feet of sandy beach frontage. The park encompasses the Tobico Marsh, one of the largest remaining freshwater coastal wetlands in the Great Lakes ecosystem. Visitors can access a network of trails spanning over seven miles, traversing diverse habitats including oak savannah, prairies, and forested wetlands. The park offers 193 modern campsites equipped with electricity and fire pits, along with day-use picnic areas and playgrounds. A visitor center provides educational exhibits regarding the local migratory bird patterns and the regional ecology. The park serves as a primary access point for birdwatchers tracking the spring and fall waterfowl migrations. Swimming is permitted in the designated beach area during the summer season.
