Mackinac Island (/ˈmækɪnɔː/ MAK-in-aw) is a city in Mackinac County in the U.S. state of Michigan. In the 2010 census, the city had a permanent population of 492, although there are hundreds of seasonal workers and thousands of tourists during the summer months.
According to the United States Census Bureau, the city has a total area of 18.84 square miles (48.80 km), of which 4.35 square miles (11.27 km) is land and 14.49 square miles (37.53 km) is water. The City of Mackinac Island exists on the island of the same name, and it also nominally includes the entirety of nearby Round Island, situated in the Straits of Mackinac immediately to the south, which is uninhabited, and is owned and overseen by the United States Forest Service in its entirety, and is managed as part of the Round Island Wilderness Area and the Hiawatha National Forest.
While all of Mackinac Island, the landform, is located within the corporate limits of the City of Mackinac Island, today 82 percent of the island’s landmass is owned by the State of Michigan and managed by the Mackinac Island State Park Commission (MISPC). The City has direct jurisdiction over only 18 percent of the island. The City and the Commission work together on the many issues affecting both the City and the State Park, such as the longtime ban on motorized vehicles on the island.
To get to the island, one can take one of many ferries across Lake Huron. The city of Mackinac Island is one of only seven municipalities in the state of Michigan to consist entirely of islands, including Grosse Ile Township, Drummond Township, Bois Blanc Township, St. James Township, Peaine Township, and Sugar Island Township.
