Munich does children well and unfussily — a world-class science museum, a zoo laid out by continent, and enough hands-on places to fill a rainy week.
Deutsches Museum
Museumsinsel 1, open daily 09:00–17:00, with about 25,000 exhibits across 20 permanent halls and push-button demonstrations throughout. 16 € adults, 9 € for ages 6–17, 33 € for a family of two adults with their own children, and free under 6. Half a day minimum.
Tierpark Hellabrunn
The first zoo in the world laid out by continent rather than by species, with more than 500 species and an aquarium, at Tierparkstr. 30 and open 365 days a year. 21 € adults and 9 € for children 4–14, or 46 € for a two-parent family card. Tram 25 to Tiroler Platz.
Bavaria Filmstadt
The working studio backlot at Bavariafilmplatz 7 in Geiselgasteig, south-east of the city. The Filmstadt Kombi — guided studio tour plus the 4D cinema — is 24 € for adults and 21 € for ages 6–17; VR games are 9 € extra. Tours are the reason to come, so check the German/English times before travelling out.
Kindermuseum München
A proper touch-everything museum for ages 4–12 at Willy-Brandt-Allee 10, with one big changing exhibition rather than a permanent collection. 5.50 € per person or 16 € for a family of up to five. Term-time it opens Thursday and Friday afternoons and 10:00–17:00 at weekends; in the holidays daily except Monday.
SEA LIFE München
Inside the Olympiapark, so it pairs with a run around the park afterwards. Book online and tickets start at 20 € instead of 25 € at the door, with family packages from 54 €; open from 09:00 with last entry an hour before closing. Small enough to do in 90 minutes.
