Austin summers are long and genuinely punishing, and the city’s answer is water. Not pools in the ordinary sense — springs. A limestone aquifer runs under this city and pushes cold water up through it, and the places where that happens have been the social centre of Austin summer for over a century. Deep Eddy Pool has been open since 1915. Barton Springs Pool is the reason Zilker Park exists in the shape it does.

This guide covers what is in the city, what needs a reservation, what is a day trip, what it costs, and the one thing that ruins more Austin swimming plans than anything else: turning up at a creek that is not running.

Barton Springs Pool: the one everybody means

Barton Springs Pool in Zilker Park is a three-acre spring-fed pool that holds roughly the same cool temperature all year, which is why you will see people swimming laps in it in January. Hours are typically 8am to noon for lap swim and noon to 8pm for recreational swim, daily, with closures for cleaning.

Admission is $9 for adults, $5 for juniors aged 12 to 17 and seniors 62 and over, $4 for children 1 to 12, and free for babies. It is free from late autumn through early spring — a fact worth knowing because the water temperature barely changes, so an October swim costs nothing and feels the same as a July one. There is also a free unguarded early-morning window before lifeguards come on, posted as swim at your own risk, and it is the local move. No reservations.

Practical notes: the grass slope on the south side is the sunbathing side and it fills first on a hot weekend; parking in Zilker is difficult from late morning through the afternoon and the walk in from overflow parking is long and unshaded. Come before 10am or after 5pm in high summer. Food is not sold on site — Terry Black’s Barbecue on Barton Springs Road is a short walk and the standard pairing, and our Austin barbecue guide covers the rest.

Deep Eddy Pool: the oldest pool in Texas

Deep Eddy Pool dates to 1915, which makes it the oldest swimming pool in Texas. It is fed by cold well water and it is not chlorinated, so it feels and smells nothing like a municipal pool. Hours run in the same pattern as Barton Springs — roughly 8am to noon lap, noon to 8pm rec — and entry is $2 to $5 for residents, $4 to $9 for non-residents, free from late autumn through early spring.

Deep Eddy is the better choice with small children: it has a genuine shallow end and a more contained footprint than Barton Springs, and it is less crowded on a summer Saturday. It sits just west of downtown near Lake Austin Boulevard, with the Ann and Roy Butler Hike-and-Bike Trail close enough to combine the two.

The Barton Creek Greenbelt swimming holes

The Barton Creek Greenbelt is the wild version, and the reason it is not on every visitor itinerary is that it is conditional: the creek runs after rain and dries out in a hot summer. Check water levels the same day. If it is flowing, three spots are worth the hike.

Gus Fruh is the best-known, with a deep pool and the Urban Assault limestone wall that Austin climbers use — expect to share the spot with people on ropes. Twin Falls is the closest to a road and therefore the busiest. Sculpture Falls is further in, quieter, and the local favourite for exactly that reason.

Greenbelt practicalities: there is no admission and no lifeguard. Access points have small lots that fill early. Wear shoes you can walk a rocky trail in, because the approach is a genuine hike rather than a stroll, and carry more water than you think you need — the trail is exposed in places and Austin heat is unforgiving. Dogs are a normal sight on the Greenbelt and it is one of the better dog swims in the city; see our dog-friendly Austin guide.

Day trips: the Hill Country swimming holes

Some of the most photographed water near Austin is outside the city, and all of it needs planning.

Hamilton Pool Preserve is a collapsed grotto with a waterfall falling into a jade-green pool, and it is the single most restricted site in the region: reservations are required in advance and there is a per-vehicle fee. Swimming is not always permitted — bacteria levels and drought can close the water while the site stays open for looking. Check before you book.

Blue Hole Wimberley is the cypress-lined swimming hole with rope swings that shows up on every Texas list. Reservations are required for the swim season. Wimberley is a straightforward drive southwest of Austin and makes a full day with the village itself.

Krause Springs in Spicewood is $10 per adult and open daily 9am to 8pm — natural springs, a man-made pool, camping and a butterfly garden. It is the most forgiving of the three: no reservation, long hours, and space to spread out.

Jacob’s Well also requires reservations, and swimming access there has been restricted in recent years as the spring flow has fallen. Treat it as a place to see rather than a guaranteed swim.

And for open water rather than springs, Lake Travis is the local reservoir option, with public access points, boat rentals and cliff-jumping spots. Water levels fluctuate substantially with drought, which changes which ramps and beaches are usable from season to season.

Municipal pools and the practical alternative

Beyond the two famous spring pools, Austin runs a large municipal pool system, and on a weekend when Barton Springs is at capacity a neighbourhood pool is the sensible answer. They do not require advance reservations, several are free or nearly free in the shoulder seasons, and they have shade structures and actual shallow ends — which the springs largely do not. Our Austin parks guide and things to do with kids in Austin cover the family-friendly options in more detail.

How to swim in Austin without wasting a day

Five rules. First, check whether your destination needs a reservation — Hamilton Pool, Blue Hole and Jacob’s Well do; Barton Springs and Deep Eddy do not. Second, check water levels if you are heading to the Greenbelt, every time. Third, go early: the parking, not the water, is the limiting factor at every in-city spot. Fourth, swim in the shoulder seasons, because the springs stay cold and admission goes free. Fifth, bring your own food and far more water than feels necessary; the swimming is cold but the walk to and from it is not.

One local point of pride worth passing on: Austinites swim year round. If somebody tells you Barton Springs is too cold in February, they are describing a preference rather than a fact — the water is the same temperature it was in August.

Frequently asked questions

How much does Barton Springs Pool cost?

Adults $9, juniors aged 12 to 17 and seniors 62 and over $5, children 1 to 12 $4, and babies free. It is free from late autumn through early spring. There is also a free unguarded early-morning window before the lifeguards come on, posted as swim at your own risk. No advance reservation is needed.

What are Barton Springs Pool hours?

Typically 8am to noon for lap swim and noon to 8pm for recreational swim, daily. Hours shift for cleaning days and seasonal changes, so check before you drive over. The pool is spring-fed and holds roughly the same temperature year round, which is why locals swim it in January.

Which Austin swimming spots need reservations?

Hamilton Pool Preserve, Blue Hole in Wimberley and Jacob’s Well all require advance reservations – Hamilton Pool charges per vehicle. Barton Springs Pool and Deep Eddy Pool do not take reservations; you turn up and pay at the gate. This is the single most common way visitors ruin a swimming plan in Austin, so book the reserved sites days ahead in summer.

What is the oldest swimming pool in Texas?

Deep Eddy Pool in Austin, which dates to 1915. It is fed by cold well water and is not chlorinated, which is why it feels different from a municipal pool. Entrance is $2 to $5 for residents and $4 to $9 for non-residents, and it is free from late autumn through early spring.

Can you swim in the Barton Creek Greenbelt?

Yes, when the creek is running – and that is the crucial condition, because the Greenbelt’s swimming holes depend on rainfall and go dry in a hot summer. The main spots are Gus Fruh, known for the Urban Assault limestone wall that climbers use, plus Twin Falls and Sculpture Falls further along. Check current water levels before hiking in; arriving at a dry creek bed after a two-mile walk is an Austin rite of passage nobody enjoys.

Which swimming holes near Austin are worth the drive?

Krause Springs in Spicewood – $10 per adult, open daily 9am to 8pm – is the classic day trip, with natural springs, a man-made pool and camping. Blue Hole in Wimberley is the postcard swimming hole and requires a reservation for the swim season. Hamilton Pool Preserve, a collapsed grotto with a waterfall, is the most photographed and also the most restricted: reservations required, per-vehicle fee. All three are outside Austin proper – budget half a day.

Where can you swim in Austin for free?

Barton Springs Pool during its free unguarded early-morning window, and both Barton Springs and Deep Eddy for free from late autumn through early spring. The Barton Creek Greenbelt swimming holes are always free when the creek is flowing. Several Austin municipal pools are free or nearly free in the shoulder seasons as well. See our guide to free things to do in Austin for more.

Is the water cold at Barton Springs?

Yes, and that is the appeal. It is spring-fed and stays cool year round, which in an Austin August is the entire point. First entry is a shock in any month. Locals will tell you to get in all at once rather than easing in from the shallow end.
