It's definitely worth a visit. It's huge, packed with animals, and even has a children's playground, making it a perfect place for families!
However, be sure to choose the right time; weekends are incredibly crowded. The lines for the herbivore train and the car rides in the wild animal area can both take at least two hours, which might be too much for children...
Be prepared for the food; it's definitely expensive, but that's understandable for a place like this. Mineral water is 8 yuan a bottle, sausages are 12 yuan each, and freshly squeezed juice is 38 yuan (the little bottles with animal prints are what kids love). Set meals are usually over 50 yuan!
