On busy days, such as the day of Pentecost, you will be redirected to a parking space, a 1 km walk away, even if you have a parking subscription. That should not be a surprise, because that is clearly stated when you purchase the subscription. Despite the crowds, the distribution of the visitors present is generally reasonable. Only on the narrow paths does it roll up.
Nice places where you are literally among the animals, sometimes behind the glass, like with the lions, sometimes the prairie dogs literally walk in front of your feet.
Many places with shade, so you can relax on warm days too.
