The Mackinac Island State Park was established in 1875 to preserve most of the historic Mackinac Island. Composed of a total of 2.81 square miles of total park area, it takes up at least 74 percent of the total land area of the island. It was the second national park in the country, originally called the Mackinac National Park. In 1895, its management was transferred to the state government, changing its name to what it is called today.

The Mackinac Island State Park is composed of a series of different interesting historical features. It has a good amount of historic buildings, limestone caves, rock formations, and historic sites like the Fort Mackinac and Fort Holmes.
