Back caption: Making friends in the Children's Zoo / Bronx Zoo, New York City / Adults are not admitted to the Children's Zoo in the Bronx Zoo unless they are accompanied by a child. The reason is simple: this is a special section of the "Big Zoo" where the whole emphasis is on the child's approach to young and friendly animals. There is plenty of room for unaccompanied adults in the rest of the Zoo's 252 acres.
