San Francisco Zoo

See more than 250 different species of wildlife from all over the globe, many of which are endangered, at the San Francisco Zoo. There are a variety of attractions, including a children's petting zoo and an insect zoo, an Australian Walk, Penguin Island, a Primate Discovery Center, and the Otter River. It also features a one of the world's largest gorilla exhibits, a lion house, a feline conservation center, a carousel, and a kiddie train. For those looking for a more in-depth and informative visit, try the Zoo Ranger, a hand held multimedia GPS device that gives video and informative background on the exhibits as you walk around. You are able to rent them for a day at the zoo's gift shop.
