I don't know how anyone could make bad reviews about this zoo. Maybe all the animals were visible on the day I went. All I can say is that I have been to a bunch of zoo's around the country and this is with out a doubt the best zoo I have ever seen. I have not seen San Diego Zoo yet so this may change after I see that one. The displays of animals in their natural habitat were amazing, something you don't notice as much in the east coast zoos. I was just amazed at how big this zoo was and how many animals they had. As I said maybe because it was a cool August day that they all seemed to be visible.
