Zoológico de San Juan de Aragón, Public zoo in San Juan de Aragón, Mexico City

Zoológico de San Juan de Aragón is a public zoo in Mexico City with sections dedicated to different ecosystems like desert zones, coastal areas, tropical forests, and grasslands. The park houses both native and other animal species that live in these natural settings.

The zoo opened on November 20, 1964, with 104 enclosures built in about three months to hold 1,650 animals of 135 species. After a 1998 diagnosis, it closed on May 17, 1999, for a renovation that reorganized exhibits by continent and biome. It reopened on December 6, 2002, while work on some areas continued.

The redesigned layout groups animals by continent, with plazas named after Mexico, the Americas and Africa serving as gathering points. An educational area and these themed plazas host school and family activities, and a walk-through aviary in the tropical Mexico zone lets visitors step among free-flying birds.

The zoo occupies 36.5 hectares at the western end of Bosque de San Juan de Aragón, in the Gustavo A. Madero district in the north of Mexico City. Exhibits are grouped by continent, so plan a route by biome rather than wandering between scattered cages. The grounds are large; allow several hours to walk the whole circuit.

The zoo features specialized medical facilities including a quarantine area and veterinary hospital to care for the animals on-site. These facilities demonstrate the professional level of animal care maintained at the park.
