The courts are on the north side of Barton Springs Road in the rear of a large green space. This green space is just east of the Zilker Botanical Gardens. Since the courts are a ways off the road and down a grade, you can't easily see them from the road. If you turn north at the first driveway east of the Zilker Botanical gardens on Barton Springs Road, you should be able to see them.
Most courts have acceptable nets, but no boundary lines.
The other 3 courts have no hazards as of my last visit. The park is located on the west side of Lamar Blvd just south of Windsor. Bring your own net and lines. The park is fairly active during the warm months, so a pick-up game is not out of the question for the netless. Nets may be rented from Austin Parks and Recreation.
