The Southern Arizona Arts & Cultural Alliance partners with the Town of Oro Valley on these two beloved and award-winning events over one fantastic holiday weekend at Oro Valley Marketplace. The crowning moment of the festival takes place on Saturday evening, when the 35-foot Holiday Tree towering over the Marketplace is lit. The celebration will feature live entertainment from local students, activities for children, free refreshments and cookie decorating, s'mores, and a special appearance by Santa. Additionally, with more than 150 artists and exhibitors in all mediums, live performances on the main stage, food vendors, and the TUBA CHRISTMAS concert. There is no cost to attend the art festival, or to partake in the tree lighting activities. Food vendors will be onsite with food and beverages available for purchase.
