Deadwood to Polson Road Trip: Scenic Drive Through the West

The route from Deadwood, SD to Polson, MT crosses over 750 miles of the American West, tracing historic corridor US-85 and then soaring across Montana on I-94 and US-191.

A little-known fact: sections of this drive follow part of the Nez Perce National Historic Trail. The landscape shifts from Black Hills granite to high plains, badlands and finally the Rocky Mountain front.

Estimated driving time is 12 hours without stops, but you'll want to linger. For tips on how to find the best stops and hidden gems between cities, consult our guide.
