April 12 @ 10:00 am - 3:00 pm
Free
Join us the 2nd Sunday in April from 10 AM to 3 PM for a market experience that’s anything but average! Each event features a new theme with on-street entertainment, interactive art, themed activities, snacks, and drinks — plus plenty of fun for all ages.
This month: Citizen Science!
The outdoor market lines Mill Avenue between 3rd St. and University and features a curated mix of Arizona-based artists, makers, and small businesses — including a special Kids Market where young entrepreneurs showcase and sell their own handmade creations.
The event is FREE admission, family-friendly, and dog friendly!
