Zilker Metropolitan Park

When it isn’t hosting concerts such as the Austin City Limits Music Festival, a three-day event held each October, Zilker Park is a popular spot for locals to enjoy the outdoors. The 350-acre park stretches southward from Town Lake on either side of the Mopac Expressway and includes hiking and biking trails, a botanical garden, the Zilker Zephyr miniature train, and numerous playing fields for sports. The most popular spot, however, is Barton Springs Pool, where geological forces keep the water at a crisp 68 degrees Fahrenheit year-round.
