My kids weren't tall enough until they were about 4yrs old.
Its based off your childs height
They measure your kids height before hand
Theres an height chart at the ticket booth with the names of the rides the children can get on meeting the height of the rides requirement.
Almost all of the rides have different height requirements. There is a chart at the entry of the park with a height bar where you can determine what rides he/she would be able to ride before buying tickets or a wrist bracelet.
3 1/2 feet tall
Most of the rides are decided by height. Some of the rides have a requirement of 48 in, but there are several rides that smaller kids can ride with an adult. There are also a ride just for small kids.
