Missoula to Alpine Road Trip Guide: Mountains, History & Hidden Gems

The drive from Missoula, Montana to Alpine, Wyoming covers roughly 370 miles along US-93, I-90, and US-287, taking 6–7 hours without stops. This route crosses the Continental Divide at Lost Trail Pass (elevation 7,014 feet) and parallels the historic Nez Perce Trail, where in 1877 Chief Joseph and his band sought refuge.

Unique to this drive: the pavement on US-93 north of Salmon, Idaho was laid over a section of the old Bitterroot Wagon Road, used by miners and settlers in the 1860s. You can still see wagon wheel ruts near the Lost Trail Hot Springs exit.
