• Rexperience costs extra: €2 on top of the museum ticket, for ages 8 and up, so plan around younger siblings
• Free ground floor with the restaurant, museum shop and LiveScience, no ticket needed for a lunch stop
• Walk from Leiden Centraal via the LUMC exit on a signposted route, or take the bus to the Darwinweg/Naturalis stop by the entrance

Naturalis is the Dutch national museum of natural history, and a research institute too. Its galleries run from Life, which climbs from the depths of the ocean to a mountaintop, to Dinosaur age, home to Trix the T. rex, plus Ice age, Earth, Evolution and the forest of Suriname.

On the ground floor, LiveScience lets kids watch researchers and collection managers at work.
