The Indiana Dunes National Park offers sandy beaches and forested trails. This segment is a vibrant reminder of glacial geology, including the Valparaiso Moraine.

• In Wisconsin, the Driftless Area begins near Madison. This region escaped glaciation, resulting in steep ridges, deep valleys, and clear trout streams. The Kickapoo River Valley is particularly scenic; detour on WI-131 through Ontario for 20 miles of winding roads.

The drive follows US-12 from South Bend to Chicago's western suburbs, then arcs northwest through Wisconsin to Minnesota. This is not a direct interstate route; expect 7-9 hours of driving without stops. The best timeframe is late spring through early fall because winter snow can delay travel.

• US-12 is mostly two lanes through Indiana and Michigan, widening to four lanes near Chicago. In Wisconsin, it becomes a scenic two-lane highway with occasional passing lanes.
• Fuel stops are plentiful every 20-30 miles in Indiana and Illinois, but sparse in central Wisconsin. Fill up in cities like La Crosse or Tomah.
• Speed limits vary: 55-65 mph on rural US-12, 45 mph in towns. Be alert for deer, especially at dawn and dusk.
