Medora, ND to Valentine, NE: Road Trip Guide

On this 300-mile journey from Medora, ND to Valentine, NE, you'll traverse the Little Missouri National Grassland and enter the Nebraska Sandhills—a region shaped by ancient dunes and the Oglala Aquifer. The route follows US-85 and US-20, a two-lane highway that cuts through one of the least densely populated areas in the contiguous United States.

The drive takes about 5 hours without stops, but the allure lies in its emptiness: long stretches with no cell service, abrupt weather shifts, and subtle beauty that rewards the patient traveler. The phrase how to find the best stops and hidden gems between cities applies perfectly here, where a dusty side road often leads to a ghost town or a prairie dog colony.

The badlands near Medora give way to open prairie with buttes and eroded gorges. South of Bowman, you'll see the Dakota Prairie Grasslands, where bison sometimes wander onto the road. Further south, the Nebraska Sandhills begin near Valentine, characterized by rolling hills of grass-stabilized sand dunes—a unique biome with shallow lakes called kettle holes.

• Theodore Roosevelt National Park (South Unit): the main attraction near Medora, with a 36-mile scenic loop.
• Painted Canyon Overlook (I-94, exit 32): a quick stop for a view of striped badlands.
• Little Missouri River: crossing this at the ND-SD border offers a rare riparian corridor with cottonwoods and possible sightings of pronghorn.

Local commerce is sparse. In Buffalo, SD, try the Sugar Shack for homemade pies and coffee. In Valentine, NE, the Niobrara River draws kayakers and anglers. The Sandhills Journey Scenic Byway (NE-2) offers a 90-mile detour through haystack ranches and native grass pastures.
