Balmorhea State Park
A Cool Oasis in the High Desert
Dive into the crystal-clear water of the world’s largest spring-fed swimming pool. Swim, scuba dive, or just relax under the trees at this historic park in arid West Texas.
Things to Do
The Civilian Conservation Corps built Balmorhea State Park in the 1930s. Nearly 80 years later, people are still cooling off at our park.
The park has picnic sites, an outdoor sports area and a playground. Rent our group hall for your next family gathering.
The pool is open daily; swimmers pay only the park entry fee. No lifeguard is on duty. Children under 18 must have permission to swim and must be accompanied by an adult at all times. Learn more about swimming and scuba diving in the pool.
Note: Effective May 1, 2015, night scuba diving will be discontinued.
More than 15 million gallons of water flow through the pool each day, gushing from the San Solomon Springs. The pool is up to 25 feet deep, covers 1.75 acres, and holds 3.5 million gallons of water. The water temperature stays at 72 to 76 degrees year-round.
We welcome volunteers! Visit our Volunteer page to find out how you can help (search on zip code 79786), or ask at park headquarters.
Part of our mission is to protect this precious desert resource. You can help! Please respect the park and its heritage. Pick up trash, leave artifacts where you find them, treat historic structures gently, and admire but don’t harass wildlife.
Ask at headquarters about borrowing a Junior Ranger Explorer Pack for the kids!
