Vail to Dillon Road Trip Guide: Epic Scenic Drive

The 600-mile route from Vail, Colorado, to Dillon, Montana, follows the northern arc of the Rocky Mountains, crossing the Continental Divide at Tennessee Pass (10,424 ft) just west of Leadville. This is not a direct interstate shot; it weaves through two states, three national forests, and the arid expanses of Wyoming's Red Desert. One unusual fact: the route passes within 20 miles of the geographic center of the contiguous United States near Belle Fourche, South Dakota (though not visited on this route).

Driving time averages 9–10 hours without stops, but to appreciate the landscape, budget at least two days. The best stops Vail, CO to Dillon, MT include Steamboat Springs, Flaming Gorge, and the Wind River Canyon.

From Vail, head west on I-70 to exit 167 for US-131 north toward Wolcott. This climbs to the McVey Pass (7,500 ft) before dropping into Steamboat Springs.

From there, I-80 west to US-189 north through Kemmerer, then I-15 north to Dillon.
