The most direct path uses Wisconsin State Highways 42 and 57 down the peninsula, then a car ferry across Lake Michigan—the only way to avoid a long drive around Chicago. The SS Badger, the last coal-fired steamship in the US, operates daily from May to October; reserve weeks ahead in summer. Alternatively, drive via Green Bay and I-43/I-94 through Milwaukee and Chicago, adding 120 miles and three hours, but running year-round.

• Distinctive highlights: Door County's 300+ miles of shoreline; Manitowoc's maritime museum; Ludington's sand dunes; Bay City's riverfront.
• Economical fuel: Gas prices in Michigan are consistently 10–20¢ cheaper than in Wisconsin, so fill up after crossing into Michigan.
• Infrastructure: I-75 in Michigan is a modern, well-maintained freeway; both states' rural roads are well-marked.
• Ferry specifics: The SS Badger costs $85 for a car plus $17 per adult; onboard amenities include a restaurant and lounges.

The drive showcases the Niagara Escarpment's dolomite cliffs, especially in Peninsula State Park near Ephraim. On the Michigan side, the Manistee National Forest offers mile after mile of hardwood forests. Lake Michigan's climate moderates temperatures, keeping orchards productive; Door County produces over 5% of the nation's tart cherries. The only UNESCO World Heritage Site nearby is not on this route—the best stops Ephraim, WI to Bay City, MI, are the lighthouses at Algoma and Big Sable Point, both part of the state's historic lighthouse system.
