Yes, one valid Sleutelpas grants an annual one-time free entry for one person (from 1 January 2026). Please book your tickets online in advance. If you book but then cannot come, we would hugely appreciate if you could cancel your visit, so we can offer your tickets to another visitor. More information on and the terms & conditions of the Sleutelpas.

Yes, if there is no expiry date on the voucher, it is still valid. Please book your tickets online in advance.

As lift capacity is limited, please consider leaving your pram or buggy at home.  If this isn’t possible, then you’re welcome to bring it to Naturalis. Stroller wagons, bicycle carts, and bike trailers are not allowed in the museum on weekends and during school holidays. If you want to use one to carry children, then we might allow it on quieter days in the week.  Naturalis staff may refuse these at their discretion.

No, but a companion may come for free.

Yes, we have a limited number available. Please ask a staff member to borrow a wheelchair when you arrive. Unfortunately, it’s not possible to book one in advance.

Accessible toilets can be found on the ground floor and 9th floor.
