Why Visit the San Diego Zoo?

The San Diego Zoo spans over 100 acres in Balboa Park and holds one of the largest collections of endangered animals, birds, and reptiles. A unique feature of the zoo is its lush landscaping; with over 6,500 species of exotic plants, the zoo provides natural habitats and food for the animals.

The zoo boasts the largest koala colony outside of Australia and has had success breeding gorillas, chimpanzees, tigers, giraffes, hippos, turtles, and more. Wander through tropical rainforests, see polar bears in chilled pools, and explore tiger and sun bear habitats that mimic their natural environments.

Among the zoo’s main attractions are displays of endangered North American species like the California condor and black-footed ferret, an African safari area with giraffes and rhinos, and a monorail tour through various African habitats. Here, you can also see rare species like the Arabian oryx, addax, and Przewalski’s horse.

The San Diego Zoo’s History

The San Diego Zoo began with a unique vision. On September 16, 1916, local doctor Harry Wegeforth heard a lion’s roar as he drove past Balboa Park, joking with his brother, “Wouldn’t it be great if San Diego had a zoo?” Driven by this idea, Harry formed the San Diego Zoological Society. After the Panama-California Exposition, the city had surplus animals, which officials gladly handed over to Wegeforth to reduce costs. These animals included wolves, coyotes, bears, monkeys, lions, and more.

In 1917, Wegeforth started fundraising for the zoo with philanthropist Ellen Scripps, who donated $9,000 to build enclosures. In 1923, the zoo began charging 10 cents for admission, and Scripps later funded the construction of an aviary for coastal birds.

The zoo attracted global attention in 1925 when Australia donated koalas, the first of their kind in the U.S. Today, the San Diego Zoo is home to the largest colony of koalas outside Australia.
