Bentonville to Decorah Road Trip: Ozarks to Midwest

This route connects Bentonville, AR—home to Crystal Bridges and the birthplace of Walmart—with Decorah, IA, nestled in the Driftless Area. The drive covers 620 miles and roughly 10 hours of wheel time, crossing the Missouri and Mississippi rivers via I-49, I-44, I-70, I-35, and local highways. A curious fact: near the halfway point in Cameron, MO, you'll follow the original path of the Pony Express, which connected St. Joseph to Sacramento. The route transitions from the forested Ozarks to the open plains and finally into the karst topography of northeast Iowa.
