Polson to Kellogg: Scenic 3-Hour Drive with Hidden Gems

Polson, Montana, sits at the southern end of Flathead Lake, the largest natural freshwater lake west of the Mississippi. The drive to Kellogg, Idaho, covers 150 miles via US-93 and I-90, passing through the Bitterroot Mountains and the Northern Rockies. This route crosses the Idaho-Montana border at Lookout Pass, a historic mountain pass used by the Nez Perce and later by miners during the 1860s gold rush.

Before you set off, note that US-93 south of Polson follows the Flathead River, where you'll see signs for the National Bison Range. The drive takes about 3 hours without stops, but you'll want to budget extra time for scenic viewpoints and small-town exploration. Here's how to make the most of the journey.
