This sprawling campus in central Tucson boasts several notable attractions. History and culture buffs appreciate the Arizona State Museum and the University of Arizona Museum of Art while shoppers enjoy perusing the numerous vintage and budget-friendly shops near campus. If you're visiting during the fall, head over to the Arizona Stadium to watch the Wildcats take on notable Pac-12 football rivals, while basketball fans can watch the school's team play at the McKale Center come winter and spring.

The University of Arizona campus also makes a great place to simply enjoy the nice weather. Some travelers suggest you visit when classes are in session because the grounds are peaceful and the palm trees and fountains on campus add to the warm-weather ambiance. And don't forget to stop by the university bookstore to pick up some Wildcat gear before you leave.

You don't have to pay to explore the campus, but the museums do charge entrance fees and you'll have to buy your game-day tickets at least a day or two in advance. There is street parking around the campus, but there are also plenty of garages; most charge $2 per hour.
