You may want to call the HOA office and ask what pools are participating in your pool tag system.  I think, generally you can go to any pool in Kingwood.  However, there are a few exceptions. Greentree, Fosters Mill, Sand Creek, Bear Branch,  and Trailwood are all in the same group I know.  Where do you have your tags from, and where do you want to go?  That may be easier to answer
@Fallon: I believe Hunters Ridge is in there too, I live in BB and can go to HR.
