Arriving in Phoenix

Phoenix is a boomtown, and its growth has been meteoric. As the city has spread into the desert, it has enveloped many suburbs. The end result is a gigantic, diverse, prosperous, sprawling city that covers 516 square miles. Getting around is much easier with a car, and you’ll want to plan your visit around wherever you are staying.

If you love the outdoors, we recommend paying a trip to the McDowell Mountains, an entire mountain range within the city limits. The hike is spectacular, but bring lots of water and look out for critters on the trail. For a slightly tamer but still fascinating look at local flora and fauna, visit the Desert Botanical Gardens. At certain times of the year you can even visit at night for a “flashlight tour” of nocturnal desert life. If you’re ready to go from wilderness to civilization, the Phoenix Art Museum focuses on contemporary art, and it’s one of the largest in the southwest.
