Vail to Buffalo: Epic Rocky Mountain Road Trip Guide

The route from Vail, Colorado to Buffalo, Wyoming traces the old Overland Trail, a 19th-century stagecoach route. Today, it's primarily I-70 west to I-80, then north on I-25 and I-90, spanning about 500 miles. Expect 8-9 hours of driving without stops, but you'll want to linger.

Driving from Vail, you first cross the Rocky Mountains via the 10,600-foot Vail Pass. The views of snow-capped peaks and alpine meadows are breathtaking. As you descend into Wyoming, the landscape transitions to high desert and sagebrush steppe.
