Warm Mineral Springs

Warm Mineral Springs is at 12200 San Servando Ave. Touted as the possible original Fountain of Youth sought by Juan Ponce de Leon, this warm mineral spring has a constant temperature of 85 degrees Fahrenheit year-round and produces 9 million gallons of fresh mineral water a day. Visitors can swim in the buoyant waters and are encouraged to bring their own lawn chairs; lifeguards are on duty. "Mandalas for World Peace," a clay sculpture, is on display.

Picnicking is permitted. Time: Allow 2 hours minimum.
