Amersfoort Zoo is one of my favorites, because it is less than an hour's drive from my house and because the park is not very big, but there is plenty to see and do.
It is a nice cozy park and for the children enough nice places to see the animals better, such as all kinds of "secret" passages such as tunnels, bridges that often end with a slide. There are also plenty of food / beverage outlets and benches scattered throughout the park. There are also many toilets and the staff is very friendly.

All in all a great zoo, although I sometimes wonder whether certain animals can withdraw from all that attention. The tigers, for example, have windows all around in several places, so wonder if that's not too stressful for them.
