In honor of our special birthday month, children ages 3 to 11 receive complimentary admission to the San Diego Zoo, when accompanied by an adult, during the month of October! Check out some of the Zoo's youngsters, including cheetah and tiger cubs, young pygmy chimps, and our 2-year-old giant panda.
