Fourth Avenue is Tucson's answer to the counter-culture, sorta like Haight-Ashbury before the drugs got totally out of control. But even if you aren't looking for a bigger bong or another tattoo, 4th Avenue offers an eclectic assortment of shops & restaurants. It is near the University and frequented by the College crowd. Especially the bars and Pizza Parlors.
Antigone Books is a locally owned bookstore that stocks local authors. It is always crowded, but there is parking on the south side.
The Modern Streetcar travels Fourth Avenue to Main Gate Square, and the entrance to the University of Arizona, then back to Downtown Tucson and the Mercado San Agustin.
The biggest, wildest festivals in Southern Arizona occurs twice a year in the middle of this thoroughfare: The 4th Avenue Winter & Spring Street Fairs. See the when and where and what of the matter below.
