This 351-acre park is affectionately referred to as Austin's "crown jewel." Its vast grounds include Barton Springs Pool, the Zilker Hillside Theatre (home to Shakespeare in the park), the Zilker Botanical Gardens, Science and Nature Center, and Umlauf Sculpture Garden. Annually the park plays host to the Austin City Limits Festival, the Zilker Kite Festival, and the holiday Trail of Lights.
