California Academy of Sciences

The California Academy of Sciences in San Francisco's Golden Gate Park is a world-renowned science institution and the only place on Earth that houses an aquarium, a planetarium, a living rainforest, and a natural history museum all under one green roof. The Steinhart Aquarium is one of the most biologically diverse aquariums on Earth, featuring nearly 40,000 live animals across more than 900 species, including the extraordinary Philippine Coral Reef tank — one of the world's largest indoor living coral displays, home to over 4,000 tropical fish. The Osher Rainforest, enclosed in a 90-foot glass dome, showcases more than 1,600 live plants and animals, while the Morrison Planetarium transports visitors through the cosmos in an immersive 75-foot dome experience. With ongoing scientific research and robust education programming, the Academy serves as both a beloved public attraction and a leading center for natural science exploration.
