California Academy of Sciences

One of San Francisco's most beloved destinations, the renovated California Academy of Sciences is now one of the planet's greenest attractions. Explore a four-story rainforest and the world's deepest living coral reef tank, then meet a colony of African Penguins and an albino alligator. Let an immersive, all-digital planetarium show transport you into the core of our planet, or beyond the edges of our galaxy. And don't miss the museum's living roof which is both beautiful and functional - providing insulation for the building and habitat for local birds and butterflies.
