How old do you have to be

Just make sure sure your kids can walk and take care of themselves....I have 3, 4, and a 5 year old....there have been up to 10 year Olds running around with no care about their surroundings

I had my daughter 2nd birthday party there.

Ages 2 and up.

At least 2 to enjoy

I've seen parents take kids that can barely walk on the playground, so i guess its up to you
