Elf exploration tours take children and their parents through Berlin, for example, through the government district, "Prussian Berlin," or Treptower Park. Small search tasks or puzzle questions in the style of a scavenger hunt motivate the one- to two-hour discovery walks in a playful manner while also leading to interesting insights about the city's historical and political past and present. Beyond the specific monuments, the tours cover overarching themes such as "Disappeared Berlin," mobility, or "Living like the Kings." The texts convey knowledge in a child-friendly and relaxed way, making them suitable for reading aloud. The book is graphically designed with care and variety: featuring engaging elements, speech bubbles, small puzzles, and many photos.
