The route offers dramatic scenery changes. Starting in Bismarck, the landscape is rolling farmland along the Missouri River. As you head west on I-94, the terrain transforms into the rugged Badlands near Theodore Roosevelt National Park (TRNP). TRNP is a must-see: a UNESCO World Heritage Site (as part of the Waterton-Glacier International Peace Park complex? No, TRNP itself is not UNESCO but is a designated national park with spectacular geology).

Finally, the drive south on WY-130 (Snowy Range Road) or via I-80 to Saratoga passes through the Medicine Bow National Forest, with pine-covered slopes and the North Platte River.

This section challenges the notion of a dull plains drive; the diversity of ecosystems is remarkable.
