Surrounded by mountain ranges, the Greater Phoenix area encompasses more than 500 square miles of Sonoran Desert and is comprised of 24 total municipalities – each with a distinct set of characteristics, attractions and flavors that offer visitors a unique glimpse at the nation’s fifth-largest city. Greater Phoenix is one of the largest metro areas in the United States, with roughly 5 million people who live here.  Dotted with resorts and golf courses, and bounded by national forests and American Indian communities, Greater Phoenix is about the size of Delaware.
