On the six flags website, I checked the park hours over a 7 day period and the hours are as follows: Mon - Fri 10:30am - 8:00pm Sat & Sun 10:30am - 9:00pm Obviously, a few other ppls answers differ, I'm just going solely off of what the website states. Personal experience about a month ago I went on a Monday and it closed at 8pm.
9pm
It closed at 9 pm on Monday
Went on a Saturday and it closed at 9 pm. The water park closes at 6pm I believe
I think 12 or so am
