There is no need to book tickets for children under 7 years. Simply tell someone at the cash desk on arrival if you have young children with you, and they will be issued with a free ticket on site. There are always individual spaces available for children under 7 years, provided that the parent/guardian has a ticket. 

NB: availability cannot be guaranteed for larger groups with young children, e.g. preschool classes. Please contact us via email before the visit then.
