A solid, modern zoo with plenty of space for the animals and good viewing areas for you. Expect a full day of walking through large enclosures with elephants, snow leopards, penguins, and a decent tropical hall. It's clean, well-kept, and the animals generally look healthy. The Asian elephant exhibit and the walk-through lemur area are genuinely enjoyable; kids and adults both tend to linger there. Crowds are manageable on weekdays but it fills up on Swiss school holidays.
Best time is late spring through early fall (May–September) when everything is open and the outdoor animals are active. In winter you’ll still get in but many outdoor exhibits feel quieter and some paths can be icy. Expect to pay around CHF 25–35 per adult, with reductions for kids and families; budget an extra CHF 10–15 if you want food or the little train ride. Total day cost for two adults and one child usually lands between CHF 80–110 including snacks.
Honest tips: prioritize the morning for the big cats and elephants before the crowds and heat arrive. Skip the gift shop unless you need postcards — it’s overpriced even by zoo standards. Bring your own water bottle; fountains are easy to find and the food stalls are average at best.
