What are the ages can 9 year olds go

Any one above 3 years can go

My nine year old niece loved it.

Absolutely! A 9 year old should LOVE the experience, especially if he or she is a bit on the daring/adventurous side.

9 year olds can go. If a child can walk, they are generally allowed to go, but even that isn't a hard and fast rule.

They have weight restriction, as long as you are under 250lbs you can fly, kids should be able to follow directions of the instructor.

Yes

Yes,9 year olds can go
