Laramie to Polson Road Trip: Discover Montana and Wyoming

Driving from Laramie, Wyoming to Polson, Montana covers about 750 miles along US-287, I-90, and US-93. This route traverses the Continental Divide twice, climbing over 8,000 feet at Wyoming's South Pass and descending into Montana's Flathead Valley. The trip takes 12 to 14 hours of pure driving time, but you will want to stretch it over two days to absorb the scenery.

The road passes through historic mining towns, vast National Forests, and alongside the Missouri River. Along the way, you will cross the legendary Sherman Summit—the highest point on the original transcontinental railroad.
