Plan to spend 3 to 4 hours at ARTIS Royal Zoo for a well-rounded visit. This gives you enough time to see the major animal habitats, stroll the garden paths, and catch a few keeper talks or demonstrations without rushing.
If you want to visit more areas inside the park, such as the planetarium, the historic aquarium, or the botanical garden, set aside 4 to 5 hours.
For the complete experience, including optional nearby attractions like Micropia or the Groote Museum, plus time for photography and a relaxed meal, you can easily spend a full day at ARTIS.
