Bozeman to Richfield: Epic Utah Road Trip Guide

The drive from Bozeman, Montana to Richfield, Utah covers 430 miles along Interstates 15 and 70, crossing the Continental Divide at Monida Pass. This route follows the historic Oregon-California Trail corridor, where pioneers once forded the Snake River. The estimated driving time is 6.5 hours without stops, but plan for 8-10 hours to fully experience the diverse landscapes.

Fuel stops are plentiful along I-15, but gaps exist in rural Idaho. Fill up in Dillon, MT (mile 60) and Idaho Falls, ID (mile 210). Gas prices vary; expect $3.50-$4.00/gallon. Road conditions are generally excellent, but winter brings snow. Check weather alerts before departing.

The route passes through the Beaverhead Mountains, Snake River Plain, and the Wasatch Plateau. Near Idaho Falls, visit the Idaho National Laboratory, a key site in nuclear energy history.
