San Diego Zoo

"At the world-famous San Diego Zoo, you’ll essentially take a journey around the world as you explore 100 acres of habitats that resemble everything from the Australian Outback to the South African coastline. In fact, this institution cares so much about making animal enclosures authentic that it even re-creates rock formations specific to various regions, like the jagged tsingy of Madagascar. The impressive Africa Rocks exhibition debuted in 2017 and includes six enclosures, including an Ethiopian highland for baboons and an acacia woodland for leopards. The zoo is also home to more than 3,700 rare and endangered animals, like Malay tigers and both Asian and African elephants."
