• A ticket for every child, since kids get into the exhibitions free but still need one; weekday afternoons are the quietest
• No large bags or backpacks inside, and the lockers are small and limited, so pack light
• Cosmonova has its own rules: no babies under 2 or strollers in the dome, and under-10s need an adult with them

Sweden's largest museum runs from dinosaur skeletons in Fossils and Evolution to the native animals of Nature in Sweden, set in their habitats. Polar Tracks covers the Arctic and Antarctica, and Treasures from the Earth's Interior has gemstones and crystals.

The Animal Human is the most hands-on hall, where kids test how their bodies work against other animals. The building also holds Cosmonova, an IMAX dome theater 23 meters across.
