St. Ignace can be reached from the south over the 5-mile-long Mackinac Bridge. The north-south I-75 connects Sault Ste Marie, on the northern border of the United States, with Detroit. U.S. 2 connects St. Ignace with Duluth and points west.
St. Ignace has a paved runway but no commercial air service. Ferryboat lines run from St. Ignace to Mackinac Island in the late spring, summer, and fall.
The Museum of Ojibwa Culture, , 500 N. State St., on St. Ignace's waterfront, celebrates the 1671 establishment of contact between the Ojibwa (also called Chippewa or Anishinabe) people and the French-Canadians. The grounds of the Museum contains the site of the Mission Chapel, reconstructions of the "long homes" built by local Native Americans, and a gravesite believed to be that of explorer Jacques Marquette. As of January 2006, the Museum was open from Memorial Day weekend until early October of each year. The admission fee was $2.00.
St. Ignace is on the eastern end of Upper Peninsula pasty country. While the Cornish pasty is more closely identified with the hard-rock mining country of the central and western Upper Peninsula, the main dish can be found in and around St. Ignace, typically from small roadside diners on U.S. Highway 2 west of the town.
Mackinac Island-style fudge can be purchased on the town's waterfront main street.
