2131 William Barton Dr, Austin, TX 78746
Both visitors and locals alike have heard of Austin’s most famous watering hole, Barton Springs Pool, the three-acre swimming pool near Zilker Park. But it’s popular for good reason: This massive spot is fed from underground natural springs that boast a year-round temperature of 68 to 70 degrees, making it the perfect place to cool off in the summer and warm up in the winter. Pro tip: You can avoid the peak crowds and the entrance fee by visiting early (5am-8am) or after hours (8pm-10pm in the spring, 9pm-10pm in the summer). Food, coolers, and alcohol are not permitted inside; however, the rules are more lax next door at “Barking Springs,” aka, the unofficial dog-friendly spot on the Ann and Roy Butler Hike-and-Bike Trail. Here, you can wade in the famously cool spring water free of charge while petting local dogs, a definite win-win.
