11 Swimming Holes in Texas: A Hill Country Access Guide

Category: Guides

A Hamilton Pool reservation buys preserve access — not a guarantee that you can swim. Jacob’s Well can also close to swimmers while its trails remain open. Those distinctions matter more than any photograph of blue water.

Our preference is for swimming holes with a named entrance and clear rules: a city park, a state park or a private operator that welcomes visitors. These 11 swimming holes in Texas meet that access requirement. The selection covers managed spring pools, creek swims and river parks, with restrictions given before scenery.

Live-status check date: not available. This is a planning guide, not a same-day opening bulletin. Current admission amounts, seasonal calendars and dated water-quality results are not available here. Follow each operator link before travelling; no entry below should be read as a declaration that swimming is open today. Distances are approximate road distances from the named town centre.

Three reservations that need special attention

Blue Hole, Jacob’s Well and Hamilton Pool all require advance planning, but their bookings do different jobs.

Destination	Booking requirement	What still controls swimming
Blue Hole, Wimberley	Reserve a swimming session during the controlled season.	Season dates, capacity and city closure notices.
Jacob’s Well	A swimming reservation is required whenever the county authorizes swimming.	Spring flow, drought restrictions and county permission; hiking access is separate.
Hamilton Pool	Reserve vehicle entry through Travis County.	Separate swimming authorization, water-quality notices and safety restrictions.

11 Hill Country swimming holes and public-access destinations

1. Barton Springs Pool, Austin

Access: Managed public swimming pool in Zilker Metropolitan Park. Operating arrangement: Posted city hours, capacity controls and temporary closures; standard entry normally needs no reservation. Fee: Municipal admission varies by age and residency. Distance: About 3 miles from downtown Austin. Water: Spring-fed pool.

Barton Springs is our first choice for travellers who want natural spring water without an unmanaged river entrance. The water stays approximately 68-70°F (20-21°C), and the developed pool has lifeguards and clearly defined swimming space. It is not a secluded swimming hole; that structure is precisely its advantage.

Follow lifeguard instructions and the restrictions on glass, alcohol and unsafe conduct. Flooding, maintenance or contamination can interrupt access. Water quality: No dated result is available here; use the City of Austin’s pool page for operating notices and monitoring information.

2. Blue Hole Regional Park, Wimberley

Access: City park at 100 Blue Hole Lane, with swimming confined to the designated Cypress Creek area. Operating arrangement: Seasonal; book ahead for controlled swimming sessions. Fee: Paid swimming admission; use the active city calendar for rates. Distance: About 1 mile from central Wimberley. Water: Spring-fed creek.

Blue Hole earns its place for a creek swim with an actual capacity system. Reservations limit entry rather than leaving visitors to gamble on an informal roadside space. Book the swimming session, not simply a visit to the wider regional park.

Stay within the managed swimming area. Cypress Creek continuing beyond it does not create permission to cross neighbouring banks. Glass, alcohol and pets are prohibited in the swimming area, and city jumping rules apply. Water quality: No dated official result is available here. Check the City of Wimberley’s Blue Hole page for reservations and closures.

3. Jacob’s Well Natural Area, near Wimberley

Access: Hays County public natural area. Operating arrangement: Swimming is reservation-only when authorized; hiking can remain open during a swimming closure. Fee: Use the county’s active swimming calendar for admission and availability. Distance: About 6 miles from central Wimberley. Water: Karst spring.

Jacob’s Well belongs on this list because it makes the connection between groundwater and Hill Country recreation impossible to ignore. The spring feeds Cypress Creek, and swimming depends on conditions that a reservation cannot fix. Low flow, drought and resource protection can all stop swimming.

Jumping and diving are prohibited. The opening connects to an extensive underwater cave system; it is not a recreational diving invitation. If swimming is closed, treat the visit as a natural-area walk rather than seeking another way into the spring. Water quality: No dated official result is available here. Check Hays County’s Jacob’s Well page and its reservation calendar.

4. Hamilton Pool Preserve, near Dripping Springs

Access: Travis County public preserve. Operating arrangement: Book vehicle entry; swimming requires separate county authorization and can be banned while the preserve remains accessible. Fee: Vehicle reservation plus preserve admission. Distance: About 14 miles from Dripping Springs. Water: Waterfall-fed grotto pool.

The limestone overhang makes Hamilton Pool visually different from the river parks elsewhere on this list. But it is the destination we would least recommend booking solely for a swim. Bacteria, rockfall, storms and changing water levels can prevent water entry independently of your reservation.

Read the swimming notice before paying, then check again before departure. Obey trail barricades and grotto restrictions even when other visitors are beyond them. Water quality: Travis County’s dated testing and swimming notices control access; no dated result is available here. Use the Hamilton Pool Preserve page.

5. Krause Springs, Spicewood

Access: Private property welcoming paying visitors through its official entrance. Operating arrangement: Seasonal, according to the operator’s calendar. Fee: Paid day admission; camping has separate charges. Distance: About 3 miles from central Spicewood. Water: Natural spring-fed pools and a constructed pool.

Krause Springs offers something the municipal creek parks do not: spring swimming and camping on the same privately managed property. That makes it worth considering for an overnight trip rather than a quick stop between Austin attractions.

Use the business entrance and follow its pool-specific rules. Do not approach through adjoining land or assume creek access bypasses admission. Check camping availability separately from day use. Water quality: No dated official result is available here; private operation is not a public bathing-water grade. See the Krause Springs operator website for opening dates, prices and restrictions.

6. Blue Hole Park, Georgetown

Access: City park on the South San Gabriel River. Operating arrangement: Posted swimming hours and city rules, subject to closures. Fee: The park has used free public access; check the current city policy before travelling. Distance: About half a mile from Georgetown’s downtown square. Water: River.

This is Georgetown’s Blue Hole, not Wimberley’s reservation-controlled creek. Its appeal is proximity to town: a named municipal river entrance rather than a long rural approach. Check the destination carefully when searching maps or making plans.

Use the city park entrance and obey restrictions on cliff jumping. Submerged rocks and changing depth make surface appearances a poor guide to landing space. Water quality: No dated official result is available here. Consult the City of Georgetown’s Blue Hole Park page for access rules and notices.

7. San Marcos River at Rio Vista Park, San Marcos

Access: Named municipal river access at Rio Vista Park. Operating arrangement: City park rules apply; floods, construction and safety restrictions can interrupt access. Fee: Check parking and park charges separately from outfitter rentals or shuttles. Distance: About 1 mile from downtown San Marcos. Water: Spring-fed river.

Rio Vista gives this recommendation a usable entrance. “Swim the San Marcos River” is too vague: rules and conditions change along the corridor, and a tubing launch is not interchangeable with every riverbank.

Keep away from hydraulic structures, spillways and strong moving water. A spring-fed river can carry forceful current even when the surface looks inviting. Glass and litter are prohibited in city river recreation areas. Water quality: No dated result for this access point is available here; there is no single result covering the whole river. Check the City of San Marcos parks information for site-specific notices.

8. Comal River at Prince Solms Park, New Braunfels

Access: Municipal river access through Prince Solms Park; use designated entrances. Operating arrangement: City river rules and seasonal restrictions apply. Fee: Parking, river-management charges, tube rental and shuttles can be separate costs. Distance: About half a mile from downtown New Braunfels. Water: Spring-fed river.

The Comal is the tubing-oriented choice in this selection. That is useful if floating is the point of your day, but less appealing if you want quiet, uninterrupted swimming. Plan around a named public entrance or authorized outfitter rather than treating the entire river corridor as open parkland.

Read New Braunfels’ container and equipment rules before packing a cooler. Avoid swimming near chutes and hydraulic structures, and check drought or flood restrictions before hiring equipment. Water quality: No dated official result for this access point is available here. Use the city’s river-information page for current rules and closures.

9. Guadalupe River State Park, near Spring Branch

Access: TPWD public park with designated river access. Operating arrangement: Year-round park, subject to capacity and temporary closures; reserve day use for busy dates. Fee: State-park entrance admission or an applicable pass. Distance: Roughly 15 miles from Spring Branch, depending on the starting point. Water: River.

This is our straightforward state-park choice for a Guadalupe River day. The important advantage is a defined park entrance and managed access — not a claim that the river is gentle. Swimming is not separately lifeguarded.

Expect changing depth, submerged rocks, current and strainers: branches or other obstacles that let water pass while trapping a person. A day-use reservation secures access only while the park remains open; it does not override river warnings. Water quality: No dated official result is available here. Check TPWD’s Guadalupe River State Park page for alerts and admission.

10. Pedernales Falls State Park, near Johnson City

Access: TPWD public park. Operating arrangement: Swimming only in areas permitted by current park guidance; swimming and wading are prohibited in the falls area. Fee: State-park admission or an applicable pass; advance day-use reservations are recommended. Distance: About 10 miles from Johnson City. Water: River.

Pedernales Falls makes the list with a firm distinction: the landmark in the photographs is not the swimming area. Visit the limestone falls as a separate activity, then use only the river area identified by park staff for swimming.

Upstream rain can transform the river quickly. Do not remain on low rock shelves or in channels when water rises, and never enter the falls or rapids to cool off. Water quality: No dated official result is available here. The TPWD park page provides access information and alerts.

11. Colorado Bend State Park, near Bend

Access: TPWD public park with river access and spring-fed features. Operating arrangement: Swimming only where park rules and conditions permit; reserve ahead when capacity is limited. Fee: State-park admission or an applicable pass. Distance: About 10 miles from Bend to the park entrance; internal travel adds distance. Water: River and spring-fed features.

Colorado Bend suits a longer park outing rather than a quick roadside dip. Its river access and spring landscape deserve attention, but Gorman Falls is not a swimming pool. Public hiking access to the waterfall does not authorize entering restricted pools, climbing the formation or crossing barriers.

Ask which water-access areas are permitted during your visit. The Colorado River can carry strong current and submerged debris, while rural access makes an exit plan important. Water quality: No dated official result is available here. Check TPWD’s Colorado Bend State Park page for alerts, reservations and restrictions.

The Texas access rules that matter

A pin on a map is not permission to swim. Texas river frontage, creek banks and informal pull-offs can be private even beside a publicly accessible waterway.

• Use the named entrance. A public park or paying operator provides a lawful access route; it does not authorize crossing neighbouring property.
• Respect fences, signs and purple paint. Under Texas Penal Code §30.05, these can provide notice against entry. Direct instructions from an owner also matter.
• Do not extend one permission into another. Texas Parks and Wildlife Code §31.105 addresses recreational entry onto private property without consent. Fishing access, a tube rental or a preserve ticket does not automatically permit swimming elsewhere.
• Stay within the authorized activity area. This is especially important at Wimberley’s Blue Hole, Jacob’s Well, Hamilton Pool and Pedernales Falls.

How to read water-quality and weather notices

Clear water is not a test result. The EPA Beach Program primarily supports coastal and Great Lakes monitoring, so its absence at an inland Texas spring tells you little about local testing. No EPA result does not mean no testing — and it does not mean clean water.

For Hamilton Pool, use Travis County’s swimming notice. For Barton Springs, use City of Austin operating and monitoring notices. For the three state parks, read TPWD alerts. Any water-quality result should identify the location and sample date; an old result is not a guarantee about today.

• Check upstream weather, not just the sky overhead. TPWD identifies flash flooding as a major Hill Country hazard. Leave the water during rising flow and stay away from low-water crossings, dams and spillways.
• Avoid swimming after heavy rain. CDC guidance notes that runoff can carry germs into recreational water; there is no single waiting period that clears every river.
• Keep people and animals away from suspected blooms. Texas DSHS advises avoiding water with scum, mats, unusual colour, foam or strong odours.
• Do not jump or dive into unfamiliar water. TPWD warns that depth, debris and submerged obstacles cannot be judged reliably from the surface.
• Use a properly fitted U.S. Coast Guard-approved life jacket where assistance may be difficult. Keep children within close reach around spring openings, ledges and current; inflatable toys are not substitutes.

Outdoor swimming is at your own risk. Before leaving, check the operator’s opening notice, your reservation, the permitted swimming area and upstream weather. If a posted rule has changed, report it to Wild Swim Atlas with the location, date and official notice so the Texas directory can be updated.
