How long to go to Denver for, from Washington

3h 25m in the air, 1,449 miles. That is a long weekend without much friction, though three nights beats two once you add the airport time at both ends.

With roughly 22 departures a day, you are not tied to one flight: if a meeting overruns or the weather turns, there is another one behind it.

Denver is 5,119 ft higher than Washington, at 5,431 ft. Enough that a first-day hike or a hard workout will feel harder than it does at home, and enough that alcohol goes further.

Denver is the capital of the western U.S. state of Colorado and the dominant city of the Rocky Mountain Region. Founded in 1858 as the placer gold mining camp known as the Cherry Creek Diggings, the "Mile-High City" is today the most populous city within a 560-mile (900 km) radius and the center of the Front Range Urban Corridor of more than five million residents. Denver embraces its cowboy and mining past but also looks toward the future with a vibrant arts and performing arts scene, dozens of great outdoor festivals, and distinct neighborhoods each offering a unique experience. You'll find everything a cosmopolitan city has to offer including a spectacular view of and easy access to the beautiful Rocky Mountains, which arise only 12 miles (19 km) west of the Colorado State Capitol.
