Typically, the average age requirement is 6 years old and 48 inches tall to fly in a hot air balloon. For safety reason, you are unable to hold your child at any time during the flight; children do need to be able to stand on their own for the approximate one-hour long balloon flight. Also, the sound of the burners can sometimes scare younger children, this is not a constant sound you will hear, the pilot turns the burners on every few minutes to keep at a specific altitude. You know your child better than we do so we say that it is up to the parent.
