Summer Vacation 2012 - San Diego Zoo

The 100-acre (40-hectare) Zoo is home to over 3,700 rare and endangered animals representing more than 650 species and subspecies, and a prominent botanical collection with more than 700,000 exotic plants. It is located just north of downtown San Diego in Balboa Park.

The San Diego Zoo has been a pioneer in building "cageless" exhibits. It is one of the few zoos in the world that houses the giant panda. It also has the largest number of koalas outside of Australia.
