BARTON SPRINGS DISTRICT. This huge, spring-fed swimming hole is surrounded by lovely gardens and pecan trees. The pool is fed by spring waters that maintain a year-round temperature of about 68 degrees, and bubble up at the rate of 27 million gallons a day. Trivia note: Robert Redford, at the tender age of five, learned to swim at Barton Springs. Schedules vary, but usually there are lifeguards on duty between 9am-6pm. The pool closes for two weeks in early March for spring cleaning.

BASTROP. Home to the "Lost Pines," a forest of pine trees that would seem more at home in East Texas, this park offers twelve log cabins, camping facilities, a swimming pool, a ten-acre lake, hiking, golfing, and more for the entire family to enjoy. For camping reservations, call 512-389-8900.

WEST AUSTIN. Once private lands, this 232-acre preserve is now owned in part by the county and is being restored to its natural state. Its focus is a soothing green pool nourished by a 45-foot waterfall. The formation took shape millennia ago when the land above an underground river collapsed; today, it's a pastoral haven for swimming and enjoying nature. Trails wind about the property, and native vegetation and wildlife are prominent. Picnic tables and restrooms are available, but other amenities are few, and restrictions apply as to what's permitted onto the property. Thirty miles southwest of Austin.

LAKE TRAVIS. Modesty is not an option at Texas's only clothing-optional public park. Throughout the 109 acres that skirt Lake Travis, open-minded visitors sunbathe, swim, hike, or even bird-watch (several species, including the golden-cheeked warbler and black-capped viero, are protected here under the Endangered Species Act). The gay and lesbian community hosts semi-annual festivals here as well.

This 640-acre park boasts a unique swimming pool located under the falls. Hiking, biking, fishing, and picnicking are available, along with camping facilities. Located 13 miles southeast of downtown Austin off US 183. For camping reservations, call 512-389-8900.
