A spring-fed swimming pool the size of 1.75 acres that stays a constant 72 to 76 degrees year-round and is so clear you can see straight to the bottom at 25 feet deep. The pool is home to endangered species including the Comanche Springs pupfish and kids can snorkel alongside them. The San Solomon Springs Courts offer motel-style rooms right on the pool deck. Recently renovated and reopened after years of construction.
Built on the dramatic cliffs above the clear blue waters of Possum Kingdom Lake in the Palo Pinto Mountains. The water here is unusually clear for Texas and kids can snorkel and spot fish in the shallows. The park has a swim area with a rocky beach and the Longhorn Trail offers moderate hiking with canyon views.
The crystal-clear San Marcos River flows through this park with three small drops known as Rio Vista Falls that kids treat like a natural water park. The river is spring-fed and stays a refreshing 72 degrees year-round. Families can tube from City Park upstream and float down to Rio Vista in about an hour. The park is free and has restrooms and easy river access from grassy banks.
