Feel the water first: nearly 1,000 feet of spring-fed pool holding a constant 68 degrees Fahrenheit, cold enough in winter to steal your breath, cool enough in summer to feel like mercy. The springs have been a gathering place for as long as humans have lived in Central Texas. The Tonkawa people considered the springs sacred, and archaeological evidence suggests human habitation around this water source for at least 10,000 years.
Anglo settler Edwin Waller purchased the springs in 1837, just one year after Texas won independence, and families have been swimming here ever since. The pool was incorporated into the city park system in the early twentieth century. But Barton Springs is more than a swimming hole — it is an ecological indicator.
The springs are home to the Barton Springs salamander, a species that exists nowhere else on Earth and survives only in this specific water chemistry and temperature. When development in the 1990s threatened to degrade the springs through stormwater runoff and impervious cover, activists formed Save Our Springs — one of Austin's most consequential environmental movements — and won landmark watershed protection ordinances that shaped development across the city for decades.
