Need directions to the Nude Beach in Texas.

No, not Hippie Hollow.  That's easy.
I live in North Central Texas and would like to visit Corpus Christi before it starts to get too cold.  i understand that there is an unofficial nude beach somewhere near Padre Island National Seashore and Mustang Island.... but where?  I'm finding old info about beaches that may now be patrolled and ticketed (since it's not 100% legal in Texas).  How would I get to the safe one from the interstate?

edit:  I thought I posted this in a different spot.  Oh well.  Sorry.
