Driggs ID to Havre MT Road Trip: Teton Vista to Hi-Line

Space Shuttle astronauts trained on the Teton Range's rugged peaks visible from Driggs, Idaho, before Driggs became a backcountry ski haven. This road trip traces a diagonal line across two states, ending in Havre, Montana, where the Hi-Line meets the Bear Paw Mountains. The 460-mile journey can be driven in about 7 hours without stops, but plan for 2-3 days to absorb the landscape.

From Driggs, head east on ID-33 through Teton Valley, then merge onto US-20 through Idaho Falls and up to the Montana state line. The route follows I-15 north to Butte, then east on I-90/US-287 to Great Falls, and finally US-87 to Havre. Along the way, you'll cross the Continental Divide, skirt the edge of Yellowstone Country, and traverse the wide-open prairie of the Hi-Line.
