About Tucson

Learn more about the host city, Tucson.

Tucson (TOO-sawn), also known as the "Old Pueblo", is the second-largest city in the state of Arizona and the county seat of Pima County in the Sonoran Desert. It is at a higher elevation than nearby Phoenix and is correspondingly cooler. Although with half a million residents it is smaller than the capital city, its cultural life is just as vibrant.
