Zilker Park & Barton Springs Pool — Austin's Backyard
A 68-70°F natural spring-fed pool inside 350 acres of Austin's oldest park
Zilker Metropolitan Park is Austin's oldest metropolitan park, more than 350 acres right in the middle of the city, and it functions as the genuine backyard for a huge chunk of Austin's outdoor life — the Zilker Botanical Garden, the Austin Nature and Science Center, the Butler Hike and Bike Trail connecting to Lady Bird Lake, and the Barton Creek Trail, a 13-mile path running from the park toward the Lady Bird Johnson Wildflower Center. This is also the site of Austin City Limits Music Festival every October, so the grounds carry a real cultural weight beyond just being a nice green space.
At its center sits Barton Springs Pool, a three-acre natural spring-fed pool that's been meaningful to this land long before Austin existed as a city — the Tonkawa people performed purification rituals in these waters, Spanish explorers built missions nearby in the 1700s before moving on to San Antonio, and in 1837 "Uncle Billy" Barton named the springs after his three daughters, Pathenia, Eliza, and Zenobia. What makes it a genuine year-round destination rather than a summer-only stop is the water itself: fed by underground springs at a constant 68-70°F, cold enough to feel genuinely refreshing on a hot day, comfortable enough to swim in through most of the year — including late October, when Austin's own air temperature can still be pushing into the 80s or 90s.
Admission runs $5 for resident adults, $9 for non-residents, with children $2-4 — genuinely inexpensive for what it is. It's open daily 5am-10pm, with one recurring closure worth knowing about: Thursdays 9am-7pm, when the pool shuts for routine cleaning. It can also close on occasion due to flooding or elevated bacterial counts after heavy rain, so check the current status before making a special trip if there's been recent weather.
For anyone splitting time between race sessions, Zilker Park works as a genuine half-day or full-day break from the circuit — walk the trails, swim in water that's the same temperature whether it's July or October, and see the actual green heart of the city that most F1 visitors never get to beyond COTA and downtown.
Why it's special
Most host cities give visitors a choice between the event and generic sightseeing. Barton Springs is neither — it's a genuine, centuries-deep piece of Austin's actual history that happens to also be one of the most pleasant things to do in the city on a warm day, which late October in Austin still regularly is. Swimming in water this old, named by a settler for his own daughters nearly two centuries ago, in a pool the local Tonkawa people used for ritual purification long before that, gives a race weekend a genuine sense of place that a grandstand seat, however good, simply can't provide on its own.
Insider tips
- 1
The water sits at a constant 68-70°F year-round — bring a towel and expect a genuinely cold first few seconds even on a warm October day, since the spring-fed temperature doesn't track the season the way a normal pool would.
- 2
Avoid planning a Thursday morning visit specifically — the pool closes 9am-7pm every Thursday for routine cleaning, a recurring closure that catches first-time visitors who don't check the schedule.

What to avoid
Don't assume the pool is guaranteed open if Austin's had heavy rain recently — flooding or elevated bacterial counts can force a closure with little advance notice, so check current status online rather than just showing up. Don't treat Zilker Park as "just the pool" — the 350-acre park includes a botanical garden, nature center, and multiple trail systems worth exploring even if swimming isn't your priority, and limiting your visit to Barton Springs alone misses most of what the park actually offers.
