Epic Road Trip Guide: Medora, ND to Winterset, IA

The drive from Medora, North Dakota to Winterset, Iowa covers roughly 650 miles via US-85 South, I-94 East, I-29 South, and I-35 South. Expect a solid 10 hours behind the wheel without stops. Medora sits at the edge of Theodore Roosevelt National Park, while Winterset is home to the iconic covered bridges of Madison County. The route descends from the rugged Badlands to the rolling farmlands of the Midwest, crossing the Missouri River near Sioux City. One quirky fact: the town of Medora was founded by a French nobleman, the Marquis de Mores, who built a meatpacking plant here in the 1880s. Today, it's a gateway to prairie dog towns and buttes.

US-85 south from Medora is a well-maintained two-lane highway with speed limits of 65 mph. Near Belfield, you'll hit I-94 east for a straight shot to Bismarck. Fuel stops are plentiful along I-94, but once you turn south on I-29, services become sparser until Sioux City. Fill up in Bismarck or Mandan before the long stretch. The best stops between Medora and Winterset include the tiny town of Linton, ND (home to the world's largest pheasant statue) and the Sioux City Lewis & Clark Interpretive Center.

Near Vermillion, the Missouri River valley offers a sudden green break. Stop at the Little Bighorn Battlefield National Monument (a slight detour west) or the Effigy Mounds National Monument in Iowa. The route passes through the Driftless Area near Decorah, but that's east of Winterset. Local commerce includes the 1880 Town in Murdo, SD, and the Amana Colonies near Iowa City. Winterset itself has the John Wayne Birthplace Museum and the Madison County Courthouse.
