The fair has been running since before most of its shoppers were born, and it works because the street underneath it works. Here is what fills it, and the way to walk it.
The Lineup · 350 Artists on One StreetJuried art, not a swap meet
The first thing first timers get wrong is expecting a craft bazaar. The Fourth Avenue fair is a juried art show stretched down a historic street: painters, jewelers, ceramicists, metalworkers, photographers, fiber artists and furniture makers apply months ahead and are selected, which is why the same fair has run for 57 years and why Tucson treats it as a season. The booths run Fourth Avenue's length with the avenue's own permanent shops, vintage stores, bookstores and cafes open behind them, so the fair layers onto a real shopping street instead of replacing it. Around forty food booths and the avenue's restaurants handle eating, and two stages run regional music through the day. There is a spring edition too, in March, but the winter fair is the bigger draw and the one with a Christmas list attached to it. Verdict: come with the gift list. Between the juried booths and the avenue's vintage shops, this is the most productive holiday shopping day in Arizona, and it is not close.
How to Walk It · A First Timer's RouteStart at an end, work one side, and take the middle seriously
The fair fills the avenue end to end, and the classic rookie error is wandering the thick middle for three hours and running out of day. Walk it like a local: enter at one end, work one side of the street down and the other side back, and save a second pass for the booths you marked. Friday is the connoisseur's day, the smallest crowds of the three and the full pick of one of a kind pieces; Saturday is the peak, shoulder to shoulder by midday, which is a feature if you like a festival at full volume and a flaw if you do not; Sunday runs shorter, to 4 p.m., and loosens up as the day goes. Artists hold pieces but the best one-off work moves on Friday and Saturday morning, so the honest shopping advice is: if you love it, buy it, and ask the booth to hold it while you keep walking. Verdict: Friday for buyers, Saturday for the full scene, Sunday for a relaxed lap plus whatever is left. All three if you are staying the weekend, which you should be.
