In the vast hills outside Oakland, California, this award-winning zoo has more than 300 types of animals living in carefully-recreated natural habitats. The African savanna exhibit is particularly popular, with African plants and a waterfall providing a home for meerkats, monkeys, and hyenas. Children are entertained in their own zoo and with a section of rides, including an old-fashioned carousel. Adults enjoy the Sky Ride, which offers scenic panoramas of the bay and the surrounding hills.
