About Balmorhea State Park
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. The Civilian Conservation Corps built Balmorhea State Park in the 1930s. Nearly 80 years later, people are still cooling off at our park. 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 1.3 acres, and holds 3.5 million gallons of water. The water temperature stays at 72 to 76 degrees year-round.
