Austin City Limits Music Festival 2026 — Weekend One

Austin City Limits Festival returns to Zilker Park for its first 2026 weekend with three full days of major live music, food, and a field-sized social atmosphere. The Friday opening day begins at noon, with nine stages and more than 100 performances across the weekend. That makes this an all-day plan, not a single-show obligation: meet up early, work through the food options, claim a sensible base, and follow the sets that matter to your crew. ACL is one of those rare festivals where the city itself feels temporarily organized around the party, so book your logistics before you start thinking about an encore. Weekend One features a broad lineup and an unmistakably Austin mix of music, outdoor energy, and daylong discovery.
