Located in the heart of San Francisco's Golden Gate Park, the California Academy of Sciences is a unique destination that combines an aquarium, planetarium, rainforest, and natural history museum under a single roof. It offers an array of experiences, from the depths of a 40,000-strong indoor coral reef to the immersive wonders of a 75-foot planetarium and the lush, four-storey rainforest teeming with free-flying birds and exotic reptilian life.
