Choteau to Pinedale: Scenic Montana-Wyoming Road Trip

This 630-mile drive from Choteau, MT to Pinedale, WY traces the eastern front of the Rocky Mountains, a corridor defined by glaciated peaks and high-desert plains. US-89 and US-26 weave through former seafloors, uplifted fault blocks, and volcanic remnants, offering a geological cross-section of the Northern Rockies. Driving time is roughly 10 hours, not counting the many worthwhile detours.

The route passes through the Missouri River headwaters, the Beartooth Front, the Wind River Canyon, and the Upper Green River Valley. The Wind River Canyon is a highlight, with walls of Precambrian granite and Paleozoic limestone. Along the way, stop at how to find the best stops and hidden gems between cities. In Crowheart, visit the historical marker for the 1866 battle. For local flavor, the towns of Choteau, Lewistown, and Dubois offer classic Main Streets with quirky shops and diners, reflecting a ranching heritage.

US-89 south from Choteau joins US-287 at Three Forks, then hooks onto US-20/26 near Rexburg, Idaho, before reaching Pinedale.
