There is no set age a child requires a Merlin Pass from. However we do provide the following advice:
If your child is 3 years or over at the time of purchasing your Passes OR will turn 3 during the life of your Passes we recommend you purchase a Pass for them, this is because children aged 3 or over are required to pay admission when entering all attractions.*
*Please note: Children will require toddler tickets from the age of 1 at The Blackpool Tower Circus.
