Austin's largest park, Zilker Park, houses Zilker Hillside Theater, a beautiful outdoor theater. During the summer, catch free musicals, concerts and "Shakespeare in the Park". Large crowds often line the grassy hills with blankets. During the rest of the year, enjoy a variety of performances (call ahead for seasonal schedules). Bring a picnic lunch, or perhaps just some wine and cheese for a snack and watch the stars come out, in the sky and onstage. Admission is free for most events.
