Hamburger Kunsthalle

Design museum with a kids' space for playing, building and dressing up.

Museum where blind guides lead you through rooms in total darkness, with a second tour through a world without sound, best for kids from about eight.

Free central park with big playgrounds, a Japanese garden, an ice rink in winter and water light shows on the lake on summer nights.

The world's largest model railway, with miniature cities and an airport where tiny planes take off and land.
