About Barton Springs Pool
Barton Springs Pool, Texas is a three-acre spring-fed municipal swimming pool in Zilker Park in Austin, fed by the Barton Springs segment of the Edwards Aquifer and maintaining a water temperature between 68 and 70 degrees Fahrenheit year-round. The pool measures approximately 900 feet in length with depths ranging from zero to 18 feet, and has a natural rock and gravel bottom. It is managed by the City of Austin and draws close to 800,000 visitors annually.
The site has been a gathering place for centuries. The springs were named after William Barton, who settled the land in 1837. The last private owner Andrew Jackson Zilker donated the property to the city in 1918, and the city dammed the springs to create the current pool in the 1920s. The existing bathhouse was built in 1947. The pool is home to the endangered Barton Springs salamander, found nowhere else on earth, making the springs a federally protected habitat.
For visitors looking for soaking pools in Texas within a city, Barton Springs Pool is the largest and most historically significant natural spring pool in Austin. The surrounding Zilker Park offers grassy lawns, the adjacent Splash! nature exhibit, and access to the Barton Creek Greenbelt trail system.

Suitability & Accessibility
Who Barton Springs Pool Is Suitable For
Barton Springs Pool suits swimmers of all ages and most abilities, as the pool is a large, staffed city facility with lifeguards on duty during charging hours, a gently sloping entry at the shallow end, and access to a bathhouse with changing facilities and restrooms. The pool is wheelchair accessible with paved paths and ADA amenities throughout the Zilker Park site.
The water temperature of 68 to 70 degrees Fahrenheit is refreshing rather than warm. First-time visitors in summer frequently find the initial immersion a shock given the contrast with Austin's heat. The cold water is part of the appeal for most visitors and is comfortable for sustained swimming. Those expecting a warm soak will find this pool operates more like a cool natural swimming hole than a geothermal spring. The depth varies from shallow wading areas to 18 feet, so non-swimmers and young children should stay in the shallower sections near the entry steps.
For visitors seeking accessible hot springs in Texas within an urban setting, Barton Springs Pool is the most centrally located and fully developed option in Austin. The surrounding grassy lawns provide extensive space for sunbathing and relaxing between swims. Food and drink are not permitted in the pool area, but the Zilker Park surroundings include nearby cafe options. The pool is popular year-round, including in winter when cold-water enthusiasts take advantage of the free entry and lighter crowds.
Safety & Etiquette
Safety and Etiquette at Barton Springs Pool
Barton Springs Pool is generally a well-managed city facility, but visitors should be mindful of specific hazards. Lifeguards are on duty during paid admission hours from roughly 8am to 9pm during the charging season. Outside those hours, including early morning and late evening swims and the winter free season, the pool operates swim at your own risk with no lifeguard present. Visitors swimming during unstaffed hours should be confident swimmers and should not enter alone.
The pool bottom has a natural rock and gravel surface, with algae in some areas that can be slippery, particularly on the entry steps. Depths range from zero to 18 feet; swimmers unfamiliar with the layout should orient at the shallow end first. After heavy rainfall, the Edwards Aquifer recharge zone can flush elevated bacteria into the springs. The City of Austin closes the pool when fecal coliform counts exceed safe thresholds, which can occur after significant rain events. Checking pool status before visiting following rain is advisable.
Food and alcohol are not permitted in the pool area. Pets are not allowed. The endangered Barton Springs salamander inhabits the pool sediment; disturbing the pool bottom or edge vegetation is prohibited under federal habitat protections. Glass containers are not permitted on the pool deck.
The pool enforces a swimwear requirement inside the fenced area. First aid staff are available during staffed hours. Young children must be supervised at all times, as depth increases quickly past the shallow entry. Visiting on weekdays or early on weekend mornings helps avoid the heaviest crowds.
