Phoenix's Sky Harbor International Airport (PHX) is by far the largest airport in the Southwest, served by many national and international flights. International travelers from Canada, Mexico and the UK have good air access to Phoenix.

There's a fairly extensive network of Amtrak trains and Greyhound buses serving the Southwest. The Amtrak station is just south of downtown; the main Greyhound terminal is just southeast of downtown, near the airport.

Three miles (5km) southeast of downtown, Sky Harbor International Airport is connected with downtown by two Valley Metro bus lines, shuttle services and taxis. All the main car rental companies have airport offices, and many have offices in other parts of the valley or will deliver a car to your door.

Valley Metro operates weekday buses all over the valley as well as a few routes on Saturday. Most stop operating in the early evening. Riders can use credit cards to pay their fare. The DASH bus system runs weekdays from downtown to the capitol, leaving every few minutes from dawn to dusk.

Three to four hour narrated bus tours are a popular way of taking in the city's major sights. Several companies also do longer tours, such as a grueling 14 hour tour to the Grand Canyon. Truer to the Western spirit are the horse-drawn carriage tours of Old Town Scottsdale. Many companies offer 4WD tours into the surrounding desert, lasting anywhere from four hours to all day and stressing themes from ghost towns to natural history to Indian petroglyphs and ruins.
