Welcome to the Holiday Inn Express Inn St. Ignace, Michigan. Conveniently located 1/2 mile from the Mackinac Island Ferry Docks and 5 miles from the Famous Mackinaw Bridge. While visiting St. Ignace there is plenty to see and visit, Fort Mackinac, the Mystery Spot, Castle Rock, Mackinac Crossings, Mill Creek, and Tahquamenon Falls are just a few great ideas for a great vacation.
