you can't, one time I bring a bottle water and then they tell me drink the water before you go inside o put in the garbage
I don't think they're mind if you go with a bottle water there. But they sell big cups with the six flags logo a different one every year and you can use it for refills and they are free . You just need to pay for it the first time.
Just a six flags bottle. Which is okay because you can fill it up with cold water from the park free and its $1 or 2 to refill with juice and soda each refill which is not bad if your a water person.
You can bring in empty bottles and they'll gladly fill them up for you if you don't bring a bottle they give you free water in cups
The only bottle you can bring in is the six flags bottle or otherwise they will not let you bring other bottles
