The tripto catalogue lists 104 museums – from art collections and technology museums to hands-on places for children. All of them are indoors, so they work in any weather.
Museum Island in Berlin is a UNESCO World Heritage Site: five historic museums, from the bust of Nefertiti to Caspar David Friedrich, with one day ticket for all of them. The Deutsches Museum in Munich is one of the largest technology museums in the world, with aviation, space travel and hands-on stations. In Hamburg's Speicherstadt, Miniatur Wunderland shows the world's largest model railway, complete with an airport and a day-night cycle every 15 minutes. In Dresden's Royal Palace is the Green Vault, the Baroque treasury of Augustus the Strong. The Jewish Museum Berlin, in Daniel Libeskind's zigzag building, has a permanent exhibition with free entry, and the Ozeaneum in Stralsund has giant aquariums, life-size whale models and penguins on the roof.
Most museums in the catalogue are in Berlin (a dozen), Saxony (about 10), Bavaria and North Rhine-Westphalia (close to 10 each) and Hamburg. Among cities, Hamburg and Dresden follow Berlin.
In practice: allow two to four hours for a large museum. Tickets usually cost €10–24, and under-18s enter many state museums for free. Look out for cheap days: the Alte Pinakothek costs €1 on Sundays, and the Hamburger Kunsthalle is free on the first Thursday of the month from 6 pm. For Miniatur Wunderland and the Green Vault, book a time slot online.
