Missoula to West Wendover: Epic Road Trip Guide

The drive from Missoula, Montana to West Wendover, Nevada covers approximately 550 miles along I-90, I-15, and I-80, taking about 8-9 hours of pure driving time. This route crosses the Continental Divide at an elevation of 7,088 feet near Butte, then descends into the arid Great Basin. Notably, the Bonneville Salt Flats, just south of West Wendover, are remnants of ancient Lake Bonneville, which once covered much of western Utah.

From the pine forests of Montana to the sagebrush steppe of the Great Basin, the scenery changes dramatically. The highlight is the Bonneville Salt Flats, a natural wonder of hardened salt crust. Just off I-80, you can stop at the Bonneville Speedway — a flat, white expanse where land speed records are set.
