In recognition and celebration of the many cultures that were historically and are presently associated with the Santa Cruz Valley, the Tumacácori Fiesta presents the traditional creations of these cultures. The fiesta features food and craft booths, continuous live entertainment on stage, and children's activities each day. On Sunday, beginning at 10:00 a.m. in front of the Visitor Center, there is a procession through the Fiesta grounds to the historic church, followed by a traditional Mariachi Mass in front of the church. Please note that no photos are permitted during the procession or mass, or while sacred dances are being performed. (“NO PHOTOS” signs will be posted prominently at restricted times and locations.) The mission grounds and park are open throughout the weekend.
