One unusual fact: near Mackinaw City, the bridge crosses the Straits of Mackinac, where Lake Michigan and Lake Huron meet—two of the five Great Lakes, with different water colors visible on clear days.

The scenery transitions from the rocky shores of the Straits of Mackinac to the sandy beaches of Lake Huron. The Huron National Forest offers dense pine and hardwood forests with hiking trails. Near Oscoda, the Lumberman's Monument commemorates the 19th-century logging industry.
