Avoid the queues. Buy an e-ticket!
On this website you can buy an e-ticket for a particular day at the Muiderslot.
After purchasing a ticket, you will receive an e-mail with the e-ticket as a PDF file in the attachment. Please print out this PDF file and take it with you. This is your admission ticket with a unique bar code. The advantage is that you won’t have to wait in line at the ticket office and you can enter immediately by scanning your ticket at the entrance gates (on the left). Please note: the e-mail itself is not an admission ticket, only the printed PDF with a unique bar code is a valid admission ticket.
