How we calculate these figures
Straight-line distance uses the great-circle (haversine) formula between each city's centre coordinates. Road distance applies a circuity factor of roughly 1.2–1.4× to reflect that roads are not straight. Driving time assumes typical blended speeds for a trip of this length, and flight time is the great-circle distance at about 875 km/h cruise plus around 30 minutes for taxi, climb, descent and approach. The door-to-door air estimate adds about three hours for airport access, check-in, security and boarding. Real figures vary with your exact route, traffic, weather, aircraft and connections.
Denver to Salt Lake City is one of America's great mountain drives — about 525 miles crossing the Rocky Mountains via the dramatic I-70 corridor. The route passes through the Eisenhower Tunnel, Vail, Glenwood Canyon, and Grand Junction before entering Utah.
Glenwood Canyon on I-70 is one of the most spectacular stretches of interstate in the country — the highway is carved into sheer red cliffs above the Colorado River. Winter driving requires caution and chains may be needed.
Stops Along the Way
Famous for Glenwood Hot Springs — one of the world's largest mineral hot springs pools, perfectly located halfway through the canyon.
A vibrant Western Slope city surrounded by canyon country and vineyards — Colorado's wine country, surprisingly good.
A classic old mining town with excellent dinosaur fossil museums and striking canyon landscapes on the descent toward Salt Lake.
