Mackinac Island State Park's air quality benefits from the exceptional Lake Huron and Lake Michigan Straits of Mackinac island position, with consistent Great Lakes winds providing outstanding maritime ventilation around this famous car-free island. Horse-drawn carriages and bicycles as the primary transportation create essentially zero vehicle exhaust on the island, while the extraordinary open-water lake exposure on all sides generally maintains Mackinac Island among Michigan's cleanest inhabited environments throughout most of the year.
