Best Attractions & Activities: In Zilker Park, just off Barton Springs Road, Barton Springs Pool is one of Austin's famous landmarks and easily the most popular swimming hole in the city. Spring fed and over 900 feet long, the pool was formed when Barton Creek was dammed up, so it has a natural rock and gravel bottom. There are varying depths, diving boards, and stairs and ladders for entry. The water temperature averages 68 degrees throughout the year, so swimming year-round is not uncommon.. A more refreshing swim is hard to find, but the pool is often crowded, because it's not secret, it gets hot in Texas!
Outdoor Activities, Parks: This huge, spring-fed swimming hole is surrounded by lovely gardens and pecan trees. The pool is fed by spring waters that maintain a year-round temperature of about 68 degrees, and bubble up at the rate of 27 million gallons a day. Trivia note: Robert Redford, at the tender age of five, learned to swim at Barton Springs. Schedules vary, but usually there are lifeguards on duty between 9am-6pm. The pool closes for two weeks in early March for spring cleaning.
