Peoria Zoo is a compact family attraction in Glen Oak Park, with animal areas designed around African, Asian, and Australian habitats. It is not a huge metropolitan zoo, but it is one of Peoria's more reliable things to do with children.
The zoo works best as part of a Glen Oak Park visit, especially if paired with the botanical garden or playgrounds nearby. It is a pleasant half-day stop rather than a reason to visit Peoria by itself.
