To tell you the truth, Philadelphia Zoo gives me a surprising impression. After looking at it on the spot, I find that there are many places in the park, and the animals are very active. Some rare species also see their young. Although the garden is small, it has a complete range of species and a compact layout, so it does not need much physical energy to turn around, which is worth learning from similar smaller urban zoos.
It's easy to spend a whole day in this zoo. The park is very large, so it's better to wear walking shoes. The park is clean, beautiful and spacious, with all kinds of animals and even polar bears.
