1.) Barton Springs Pool
Nestled in Austin’s beloved Zilker Park, Barton Springs Pool is a popular three-acre swimming hole that attracts swimmers and endangered salamanders alike. Though it is much more developed than the other natural swimming holes on this list, Barton Springs is spring-fed and is a federally protected habitat for wildlife—we weren’t kidding about the salamanders! Besides the beautiful atmosphere and clear waters, Barton Springs’ greatest plus is its constant water temperatures of 68-70 degrees. That means year-round cannonballing, people!
