San Diego Zoo | San Diego

The San Diego Zoo is one of the most famous and respected zoological institutions in the world. Located in Balboa Park in San Diego, California, it spans approximately 100 acres and is home to more than 12,000 animals representing over 650 species and subspecies. Renowned for its pioneering role in open-air, cage-less exhibits that closely replicate natural habitats, the zoo is a leader in conservation, animal care, research, and education.

Historical Overview

Founded: In 1916, by Dr. Harry Wegeforth, a San Diego physician inspired by exotic animal displays at the Panama–California Exposition.

Originally operated by the Zoological Society of San Diego, the zoo quickly became a symbol of modern zoology.

Situated in Balboa Park, near downtown San Diego, the zoo’s hilly terrain is lush with tropical and subtropical vegetation.

The layout is organized geographically and ecologically, grouping animals by habitat and continent (e.g., African Rainforest, Asian Passage, Australian Outback).

The zoo is famous for its immersive design, such as moated enclosures, walk-through aviaries, and mixed-species habitats.
