Twenty minutes from downtown Austin, limestone ledges channel Onion Creek into a series of natural pools that have drawn swimmers for generations — making McKinney Falls the closest legitimate swimming hole to the city, no reservation-only grotto or long drive required. But that convenience comes with real variability: creek conditions here shift with the weather, and as of mid-2026, water recreation has been discouraged due to rising levels and debris. Knowing the current status before you drive out matters as much as knowing the fee schedule.
Here’s what to check and what to expect for a 2026 trip.

Check Creek Conditions Before You Pack a Swimsuit
This is the single most important thing to verify before heading to McKinney Falls in 2026. The park’s pools and falls are fed directly by Onion Creek, and creek conditions shift with recent rainfall, sometimes turning the normally calm swimming pools into fast-moving, debris-filled water that’s unsafe to enter. As of mid-2026, the park has specifically advised against swimming, fishing, or any water recreation due to rising creek levels and unknown debris.
This isn’t a permanent condition, but it does mean checking the park’s current alerts or calling ahead (512-243-1643) is worth doing the morning of your visit, not just when you first plan the trip. Trail access across Onion Creek can also be affected by the same rainfall-driven conditions, so if your hiking route depends on a creek crossing, confirm it’s passable before you commit to that path.
Why Reservations Matter More Than the Fee Suggests
At just $6 per person, McKinney Falls’ day-use fee is one of the more affordable admissions on this list, but don’t let that low price suggest casual, walk-up access is reliable. The park frequently reaches capacity, especially on weekends and holidays during its March-through-November busy season, and once that happens, day-use visitors without a reservation are turned away entirely. Visitors with camping reservations are still admitted during a capacity closure, which makes camping a legitimate workaround if a specific busy-season date matters to your trip.
If you’re planning a day trip without a reservation, arrive early and have a backup plan in case the gate closes for the day — a real possibility given the park’s proximity to Austin and its popularity as a quick escape from the city.
Old Baldy and the Historic Side of the Park
Beyond the falls themselves, McKinney Falls holds one of the more remarkable natural landmarks in Central Texas: Old Baldy, a bald cypress tree standing over 100 feet tall and estimated at more than 500 years old, found near the Rock Shelter Trail. Having survived centuries of floods and droughts along Onion Creek, it’s become a quiet highlight for visitors interested in more than just the swimming holes, and a popular subject for nature photographers drawn to its scale and age.
The park also holds historic ruins tied to its namesake, Thomas McKinney, an early Texas settler, giving hikers on the Rock Shelter Trail and nearby paths a mix of natural and historical points of interest along the way.
Trails, Biking, and What Fills a Visit Beyond the Water
With more than 7 miles of trails, roughly half of them paved, McKinney Falls offers a genuinely solid hiking and biking network independent of whether the creek is swimmable on a given day. The paved sections work well for families with strollers or casual bikers, while the unpaved trails lean toward a more rugged Hill Country hiking experience. Combined with picnicking areas, a playground, and camping options ranging from RV sites to cabins, the park holds up as a worthwhile visit even during stretches when water activities are off the table.
A few rules worth knowing before you set up for a picnic: coolers aren’t allowed directly at the falls, so plan to eat in one of the park’s designated picnic areas instead, and dogs, while welcome on a leash, aren’t permitted to swim in the creek alongside you.
Frequently Asked Questions
Q1. How can I check if swimming is currently allowed before I drive out?
Call the park office directly at 512-243-1643 or check the park’s official Texas Parks and Wildlife alerts page, along with its social media accounts, for the most current creek and swimming status. Conditions can change quickly after rainfall, so check as close to your visit date as possible.
Q2. Is McKinney Falls still worth visiting if swimming is restricted?
Yes. The trail network, Old Baldy, the historic rock shelter and ruins, and general picnicking and hiking remain available regardless of creek conditions, so a visit isn’t wasted even if the falls themselves aren’t swimmable that day.
Q3. Do I need a reservation for a weekday visit, or just weekends?
Weekday visits are generally lower risk for capacity closures, but reservations are still recommended year-round since the park’s proximity to Austin means demand can spike unpredictably. Weekends and holidays during the March-through-November busy season carry the highest risk of a walk-up closure.
Q4. Can I bring my dog to swim in the creek with me?
No. Dogs are welcome throughout the park on a leash, but they’re not permitted to swim in the water, including during periods when swimming is otherwise open to visitors.
