The Barton Springs Pool is a natural spring-fed swimming pool located within Austin, inside the larger Zilker Park. Fed by underground springs from the Edwards Aquifer, the pool maintains a year-round average temperature of about 20–21°C, making it a popular swimming spot in both summer heat and cooler months. Its clear, turquoise waters and natural setting have made it one of Austin’s most iconic outdoor destinations.

The pool has a long history of use, originally serving as a gathering place for Indigenous peoples before becoming a recreational site in the 20th century. Over time, it was developed into a protected public swimming area while still preserving its natural spring ecosystem. It is also home to the endangered Barton Springs salamander, a species found only in this environment, which has led to careful environmental protections and monitoring.

Today, Barton Springs Pool is a beloved community space that reflects Austin’s outdoor lifestyle and environmental awareness. It attracts swimmers, sunbathers, and families year-round, offering a rare combination of natural beauty and urban accessibility. As both a recreational landmark and an ecological preserve, it remains one of the most cherished spots in the city.
