Barton Springs Pool is the crown jewel of Austin’s outdoor scene—a three-acre, spring-fed pool with water that stays a refreshing 68-70°F year-round. Located within Zilker Park, the pool is fed by underground springs from the Edwards Aquifer, creating some of the clearest, cleanest swimming water in Texas.

A local favorite since the 1800s, the pool has seen everyone from Indigenous tribes and early settlers to hippies and celebrities take a dip. It’s even been called the “Soul of Austin”—a place where locals and visitors alike lounge on grassy slopes, swim alongside fish and turtles, and soak in the city’s laid-back vibe.

Barton Springs is swim-at-your-own-risk, with lifeguards on duty during peak hours and a deep end that plunges to 18 feet. Sunbathers relax on the banks, while thrill-seekers take the infamous diving board plunge. The pool is also home to the endangered Barton Springs Salamander, a tiny amphibian found nowhere else in the world.

With its rich history, crystal-clear waters, and unbeatable summer vibes, Barton Springs Pool is an absolute must-visit—whether you’re cooling off after a hike, floating under the sun, or just experiencing one of Austin’s most beloved spots.
