With literally thousands of wild animals including many on the endangered species list, its no wonder that San Diego Zoo is world famous. With more than 4,000 animals representing 800 species, San Diego Zoo is home to a diverse collection of animals, many of which are rarely seen at other zoos. Either either spend another day at the San Diego Zoo, or receive admission to the San Diego Zoo Safari Park, located about 35 miles (55 km) away from the zoo. At the San Diego Zoo Safari Park, you will be inspired by the African Serengeti and the endless expanses of the Asian plains, the 1,800-acre San Diego Zoo Safari Park offers you an exotic safari adventure unlike any other outside of Africa itself. San Diego Zoo Safari Park is home to more than 3,500 rare and exotic animals – most of whom roam freely in vast enclosures.
