This zoo is humongous with an amazing animal variety; but even more fascinating is the incredible variety of plants! Their conservation efforts are outstanding and they continue to improve …. renovations and expansions are underway at this time. The workers and keepers are friendly and very proud of what the Zoo has accomplished. The zoo has a great diversity of wildlife from around the world and some exhibits that focus on Southern California as well. You can spend a whole day here as there is so much to see and do.
