Barton Springs, Austin, Texas

Have anyone experienced Barton Springs yet ?

I saw in one place only mentioning it was clothing optional.
Everywhere else it says women can go topless because Austin has passed a le for equity between men and women, so women can be topless everywhere a man can.

But can you Ly on your towel and swim naked there ?
Probably be alone, for sure.

But I am looking at trying to visit once in the evening, or early morning.

Any tips appreciated.

And if not allowed, minimalistic swim thong, ok ?
