On weekends how soon does the park fill up/reach capacity?

It filled up before 10 a few weekends ago. The earlier you get there the better tbh

I know when we have went we were in line by 730 and it fills quick in the summer. I would say by 10am 11am

Always busy on weekend

It fills up pretty quickly in the weekends. But I'd suggest Rum Island. It's on the other side of the river, but also fills up fast and is just the springs and boat ramps...

10 am
