The best swimming hole in the Hill Country is Hamilton Pool Preserve, and you will not get in without a reservation. The rest depends on your tolerance for planning:
Top pick
Hamilton Pool Preserve, Dripping Springs — book the moment the window opens.
Coldest water
Jacob's Well, Wimberley — 68 degrees, year round, no exceptions.
No reservation
Krause Springs, Spicewood — privately owned, first come, bring cash.
With kids
Blue Hole Regional Park, Wimberley — shallow entry, lifeguards, real shade.
Every summer somebody drives ninety minutes to a swimming hole, finds a gate and a sign
about reservations, and turns around. It has happened to me twice. The Hill Country’s
best water is now mostly booked, capped, and metered, which is annoying on a Saturday and
the reason any of it is still swimmable.
So this list is organized around getting in, not just what the water looks like. Twelve
sites between Austin and Uvalde, swum on a weekday and a weekend, with the fee, the
booking window and the walk from the parking lot written down.

The best Hill Country swimming holes, ranked, with town, what they are known for, entry fee and rating out of five.
We swam every one of these at least twice between April and September 2025, on a weekday and a weekend, and timed the drive from central Austin both times. Four things decided the order:
1The water. Clarity, temperature and whether it holds up in a dry August. Spring-fed beat river-fed in every dry-year comparison we made.
2The getting in. Reservation systems, entry fees, gate hours, and how far you walk from the car with a cooler.
3The crowd. How many people the site can absorb before it stops being pleasant, and what time on a Saturday that happens.
4The facilities. Shade, restrooms, lifeguards, and whether there is anywhere to change.
Fees and reservation rules were confirmed with each site in June 2026 and change more often than anything else on this site. Water levels are checked against USGS gauge data, not against what a listing page says. Nothing here is sponsored.

A limestone dome collapsed here several thousand years ago and left a jade pool sitting
under fifty feet of overhanging rock, with Hamilton Creek falling into the far end of
it. Nothing else in Texas looks remotely like this, which is why Travis County caps
attendance and why the booking page is the hardest reservation in the Hill Country
outside of a Big Bend campsite.
Book at the top of the release window and take a morning slot. The afternoon light is
worse, the walk back up is hotter, and the water quality closures, when they come, tend
to be announced late in the day.
Heads up:
swimming is suspended after heavy rain while bacteria levels are tested, sometimes
for two or three weeks. Your reservation still gets you in to look.

An artesian spring that drops into a cave system nobody has fully mapped, and stays at 68 degrees whatever the air is doing.
The spring mouth at Jacob's Well, Wimberley
Sixty-eight degree water rising out of a cave system nobody has fully mapped.
Jacob’s Well is a twelve-foot opening in a creek bed that drops into a cave system
divers have followed for more than a hundred and forty feet without finding the end of
it. The water comes out of the aquifer at 68 degrees and stays there in January and in
August, which in a Texas summer feels like being handed something you did not earn.
Hays County sells two-hour slots, and the cap is low enough that the place is quiet even
in July. There is a short walk from the lot, a set of stairs, and then very cold water.
Know before you go:
jumping into the shaft itself is prohibited and the rule is enforced. Several people
have died in the cave system since 1979.
Thirty-two springs on private land the same family has held since 1955, with a man-made pool up top and a cypress-shaded natural one below.
The rope swing at Krause Springs, Spicewood
Thirty-two springs on land the Krause family has held since 1955.
The Krause family has owned this land since 1955 and has never once been talked into a
reservation system. There are thirty-two springs on the property, a man-made pool at the
top fed by the coldest of them, and a natural pool below in a stand of cypress with the
rope swing that shows up in everyone’s photographs.
The trade for skipping the booking page is the gate. On a hot Saturday the lot is full
by eleven and they close it. Arrive before ten or plan on a weekday.
Bring:
cash, a towel you do not mind losing, and shoes you can walk on limestone in.

Cypress Creek runs through a stand of trees older than the town, and the city has managed it about as carefully as a swimming hole can be managed.

Wimberley bought this stretch of Cypress Creek in 2005 and spent a decade turning it
into the most competently managed swimming hole in the region. There are lifeguards. The
restrooms are clean. The entry shelves gradually instead of dropping, which matters if
you are bringing a five-year-old.
Purists find it too municipal. They are not wrong, and they are also not the ones
carrying a toddler and a cooler across a limestone shelf.
Book it:
peak swim slots go about two weeks out, and the whole park closes to swimming outside Memorial Day to Labor Day.
Three miles of the Frio, a 1930s pavilion, and a jukebox dance that has run on summer nights since 1941.
The Frio River through Garner State Park
Three miles of river frontage below the 1930s pavilion.
Garner is a state park rather than a swimming hole in the strict sense, but it has three
miles of the Frio River and the Civilian Conservation Corps built the pavilion in the
late 1930s, so it earns its place. The jukebox dance has run on summer nights since
1941. Teenagers still go. Their grandparents met there.
The catch is the river itself. In a wet year the Frio at Concan is clear, green and
chest-deep. In a dry August it is a series of puddles connected by gravel. Check the
gauge before you commit to the drive from Austin, which is two and a half hours in the
best conditions.
Best for:
an overnight: swim the Frio all afternoon, then stay for the jukebox dance that has run every summer night since 1941.
In a Texas August, cold water is not a luxury. It is the only part of the day that works.

Frequently Asked Questions
What is the best swimming hole in the Texas Hill Country?
Hamilton Pool Preserve, outside Dripping Springs, for the collapsed grotto and the fifty-foot overhang. Reservations are required all year and sell out fast. Jacob's Well in Wimberley is the pick if you want the coldest water.
Do Hill Country swimming holes require reservations?
Most of the good ones do. Hamilton Pool, Jacob's Well and Blue Hole all run booking systems, and turning up without one means being turned away at the gate. Krause Springs is the main exception, and its lot fills by late morning on summer weekends.
How cold is the water at Jacob's Well?
About 68 degrees, all year, because it comes out of an artesian spring rather than sitting in the sun. That feels sharp in June and pleasant in September.
When is swimming season in the Hill Country?
Roughly May through September. Blue Hole runs Memorial Day to Labor Day, Jacob's Well allows swimming May 1 to October 1, and Hamilton Pool opens for swimming when bacteria levels and rainfall allow, which is not every week.
Are Hill Country swimming holes affected by drought?
Heavily. Spring-fed sites like Jacob's Well and Krause Springs hold up better than river sites, but the Frio at Garner can drop to ankle depth by late August in a dry year. Check the USGS gauge for your river before you drive.
Can you bring dogs to Hill Country swimming holes?
Not to Hamilton Pool, Jacob's Well or Blue Hole. Garner State Park allows leashed dogs in most areas but not in the swim zones. Krause Springs permits them at the campground only.
