Adult tickets: €14, Child tickets: €12 (up to 3-9 years old). It’s fun to visit various microbes. My kids love to see them up close under a microscope. Children also love to see leaf slices, ant exhibits, giraffe specimens, etc. The restaurant had a lot of fun. We were a bit tight and so we spent 45 minutes to an hour visiting. I highly recommend anyone who comes to Amsterdam to visit here.
