Based in Golden Gate Park, the California Academy of Sciences is the only place on Earth to house an aquarium, planetarium, and natural history museum...all under one living roof. From the splashing penguins in African Hall to the wildflowers on the roof, the building is bursting with life. A four-story living rainforest and awe-inspiring coral reef ecosystem showcase Earth's biodiversity, while an immersive planetarium shows offer a new perspective on the planet.
