They really don't close there is just no lifeguards on duty during certain times.
SAB (BC/YC) and maybe 1 other are the only ones that close.
Well I stand corrected i guess they do close. I just don't remember but maybe it's because we don't really swim that late but do remember people being in them that late.
The pool hours for POP are listed as 7 am to 12 midnight. Life guards were onduty most ights till 10 or 11 just deoended on weather, We just returned from there on 7/25. If you have any other questions let me know.
They DO close and you CAN be kicked out if you are swimming at a time when it is closed. But that is if someone reports you, which means you were probably making too much noise. I think after 10PM it is quiet time at the pools, and you are supposed to be more quiet then as well.
