Garden City to Kellogg: Scenic Utah-Idaho Road Trip Guide

The route from Garden City, UT (elev. 5,970 ft) to Kellogg, ID (elev. 2,300 ft) traverses the Wasatch Range, Bear Lake Valley, and the Bitterroot Mountains—a 300-mile journey that drops over 3,600 feet.

The drive passes through a unique geological transition where the Basin and Range province meets the Northern Rockies, offering travelers a microcosm of Western American landscapes.

You'll cross the Continental Divide at Monida Pass (6,860 ft) in Montana, a subtle crest that diverts water to the Pacific and Atlantic oceans. This exact point is historically significant as a former stagecoach route on the Montana-Utah stage line.

Beyond the elevation change, the route carries a local quirk: deer and elk crossings are common at dawn and dusk, especially near the Idaho-Montana border—drive with extra caution during these times.
