Red Lodge to Kellogg: Montana to Idaho Road Trip Guide

Red Lodge, Montana, sits at the foot of the Beartooth Highway (US-212), a road famously described by Charles Kuralt as “the most beautiful drive in America.” Kellogg, Idaho, is a former silver-mining hub turned mountain-bike mecca. The direct route via I-90 West covers about 450 miles and typically takes 7 to 8 hours of driving time, not counting stops. But the real treasure lies in the detours.

This stretch crosses the Continental Divide twice, passes through the Gallatin National Forest, and skirts the edge of Yellowstone National Park. Drivers encounter a dramatic shift from Montana’s high plains to Idaho’s rugged Bitterroot Range. It’s worth driving Red Lodge, MT to Kellogg, ID for the sheer diversity of landscapes alone.

The drive west from Red Lodge follows the Stillwater River valley, with views of the Beartooth Mountains. Once on I-90, the landscape opens to rolling ranchlands, then climbs into the Gallatin National Forest near Livingston. The Madison River parallels the highway from Bozeman to Dillon, offering blue-ribbon trout fishing access.

Local commerce thrives in Butte and Missoula. Butte’s historic Uptown district features preserved copper-mining architecture and the World Museum of Mining. Missoula is a college town with a vibrant downtown, breweries, and the Clark Fork River running through it. In Kellogg, the Silver Mountain Gondola takes visitors to a ski resort and mountain bike park.
