Austin, Texas Tourist Attractions
"In the summer, sun-drenched Austinites and visitors alike find solace in the naturally cool Barton Springs Pool, the backbone of Zilker Park. After a hike around Lady Bird Lake or a suspenseful game of Frisbee with the dog, the springs provide much-needed relief. Other attractions like the Zilker Botanical Gardens and Umlauf Sculpture Garden make the park a year-round playground."
