Gatlinburg to Bentonville Road Trip: Scenic Drive Through Appalachia

This 680-mile drive from Gatlinburg, Tennessee to Bentonville, Arkansas follows US-321, I-40, and I-40W/I-44 through the heart of the South. The route crosses the Appalachian Mountains, the Tennessee River Valley, and the Mississippi River, ending in the Ozark Plateau.

Gatlinburg sits at the border of Great Smoky Mountains National Park, while Bentonville is the headquarters of Walmart and a growing arts hub. The drive typically takes 10 to 12 hours without stops, but lingering at the recommended attractions can extend it to a full day or two.
