If there is one thing you must do when you visit Amsterdam, it is to tour the Anne Frank House. The museum is incredibly well done and very moving. You are able to walk through the actual rooms where the Frank family hid during the Nazi invasion, and television screens and posters tell the story chronologically. Pin-drop silence represents the impact that the story has over all guests and the respect people show towards the victims of the Holocaust.
We bought tickets to visit the museum ahead of time and walked right in, but if you don’t purchase tickets in advance, you will have to wait in very long lines (pictured below). Purchase tickets weeks-months in advance to avoid the line here. NOTE: No photography is allowed inside the museum.
