The primary route is I-75 north from Frankenmuth to the Mackinac Bridge, then US-2 west across the Upper Peninsula. After US-2, take MI-28 west and then US-41/MN-61 along the North Shore to Grand Marais. Fuel is available in towns every 30-40 miles, but distances can be longer in remote areas. Plan fuel stops at St. Ignace, Manistique, Munising, Marquette, Houghton, and Grand Marais.

Road quality is generally excellent: I-75 is a modern interstate, US-2 is a well-maintained two-lane highway, and MN-61 is a scenic byway with good pavement.
