Missoula to Afton: A Scenic Drive Through Rugged Rockies

By admin, 24 July, 2026

Introduction

This route from Missoula, Montana to Afton, Wyoming roughly follows US-93 and US-26, crossing the Continental Divide near Monida Pass. The 250-mile drive takes about 4.5 hours without stops, but you'll want to linger. Historically, this corridor was part of the Oregon Trail and later the stagecoach route to Yellowstone.

Key highways include US-93 South from Missoula, then US-20 East at Spencer Junction, merging onto US-26 East into Wyoming. The road is mostly two-lane, with sections of four-lane divided highway near Dillon, MT. Is it worth driving Missoula, MT to Afton, WY? Absolutely—the landscape shifts from Montana's ponderosa pine forests to Wyoming's sagebrush steppe, with the Teton Range looming southward.
