Unless they have changed it recently, the max height is 48 inches. I'm bummed cause that means that DD won't be able to play in that area this trip. But last time we were there, a little girl hit her head on part of the play structure and was bleeding pretty badly. The little girl was taller than my DD (who was already a bit over the height limit). So apparently they haven't always been as strict about the height rule. But it's understandable why they started to enforce it. And I'd rather deal with a disappointed kid than an injured kid.
