Butte to Hanksville Road Trip Guide: Highways, History & Hidden Gems

The drive from Butte, Montana to Hanksville, Utah covers roughly 520 miles via I-15 S and US-6 W, taking about 8 hours without stops. Butte sits at a mile high on the Continental Divide, while Hanksville lies in the red rock desert near Goblin Valley State Park. The route passes through at least three distinct climate zones: high plains, rugged mountains, and Colorado Plateau desert.

Along the way, you’ll cross the path of the 1805 Lewis and Clark Expedition near Dillon, MT, and later the historic Mormon Pioneer Trail in central Utah. A fascinating fact: the stretch of I-15 between Dillon and Salt Lake City is one of the few interstates that crosses the Continental Divide twice. The highway also skirts the Utah Test and Training Range, a military zone where you might see F-35s streaking overhead.
