Philadelphia Zoo

Philadelphia Zoo, the oldest zoo in the United States, offers diverse animal exhibits, conservation programs, and formal educational offerings that pair well with biology and ecology studies. Established in the 19th century, it now highlights species survival plans and environmental challenges alongside traditional viewing areas. Parents like that visits can be focused—by biome, continent, or theme—and that the zoo often provides downloadable learning materials. Admission and parking aren’t cheap, but memberships or reciprocal zoo programs can stretch the value of frequent, focused visits.
