California Academy of Sciences
The California Academy of Sciences in San Francisco's Golden Gate Park holds a singular distinction: it is the only institution on Earth that combines an aquarium, a planetarium, a living tropical rainforest, and a natural history museum under one roof. Behind its lush living roof, visitors encounter nearly 60,000 live animals, soar beneath free-flying birds in a four-story rainforest, travel through deep space on a 75-foot dome screen, and walk among dioramas, fossils, and gem collections that span the history of life on our planet. A single ticket grants access to everything: the Steinhart Aquarium's biodiverse habitats, the newly refreshed Osher Rainforest, the Morrison Planetarium's immersive shows, and the Kimball Natural History Museum's hands-on galleries. Whether you have two hours or a full day, the Academy rewards curiosity at every turn.
