Phoenix stretches a stunning 517 square miles, and due to lying in the middle of the Sonoran Desert, daily summertime temperatures commonly exceed 100 degrees. This is easily one of the hottest places in the country! More than 586 miles to the Northeast of the valley is Denver, the destination and respective capital of Colorado.

The trip to The Mile-High City will take Phoenix residents from an elevation of 1,100 feet all the way up to 5,280 feet above sea level. It can take a little while for people to adjust the sheer change in altitude, so allow your body enough time to adapt to the mountainous environment before getting out and about. Non-stop flights from Phoenix to Denver are offered by Continental Airlines, United Airlines, and US Airways.

The biggest commercial airport in the Southwest is located a few miles southeast of Phoenix’ downtown district; Sky Harbor International is operated for joint military and public use, and is ranked among the United States’ top 10 busiest airports.

A focal flight zone for US Airways and Southwest Airlines, Phoenix’ primary airfield features 3 terminals and 120 passenger gates. PHX Sky Train is Sky Harbor’s most recent, large-scale renovation. By 2020, this automated people mover system will greatly facilitate the movement of passengers between the Light Rail station, parking lot, and on-site Rental Car Center.
