We can only guarantee access with a ticket booked for a specific time slot or a timeslot reservation.

Our online admission tickets already include a timeslot, no further reservation is necessary. All other ticket types require a timeslot reservation.

As part of the precautions to contain Covid-19, we have capacity limits which we ensure by pre-booking. If a day can no longer be booked, we have no more capacity on that day. In this case please select another day for your visit.
