Balmorhea State Park Springs

Balmorhea State Park, in the high desert of far west Texas between the Davis Mountains and the Chihuahuan Desert, contains the San Solomon Springs complex, one of the largest spring-fed swimming pools in the world, its crystal-clear constant-temperature waters maintaining 22 degrees Celsius year-round and sustaining a unique desert oasis ecosystem including the endemic Pecos gambusia fish. The sodium and calcium-rich spring waters of San Solomon Springs are fed by an ancient aquifer system emerging from the limestone geology of the Trans-Pecos desert, offering therapeutic swimming and snorkelling in waters so transparent that visibility extends across the entire 1.75-acre pool surface. The stark Chihuahuan Desert landscape surrounding the oasis, the nearby McDonald Observatory atop Mount Locke with its exceptionally dark stargazing skies, and the authentic west Texas ranching culture of the Davis Mountains region create a dramatically beautiful and remote spa destination in the Trans-Pecos wilderness.
