Austin City Limits is updating its COVID protocols ahead of this year's festival. Attendees will be required to show proof of vaccination or a negative COVID test within 72 hours, but organizers say masks will still be required in areas of Zilker Park where it is difficult to maintain social distancing. This includes entrance lines, the merchandise store, and areas closest to the stage. The festival's shuttle buses will also require face coverings while onboard. A-C-L says free masks will be available at each entry gate.
