Dick Nichols Park in Southwest Austin is filled with some great recreational facilities. There's a very nice multi-purpose track encircling the park, there are tennis courts, a couple of sand volleyball courts, a great playground for little kids, and the big Dick Nichols pool.
The pool was renovated a year ago and now is one of the few neighborhood pools open year-round. You'll find men's and ladies bath houses on either side of the pool area; they're somewhat basic but they're also clean and everything works: toilets, showers, changing areas.
This is a really decent pool. It has only two major drawbacks: (1) there is no shade anywhere near the pool, so if you're sitting down out of the pool you're going to be sitting in direct sunlight; and (2) if you are sitting down, you'll get acquainted with a million ants real fast.
