Stroll into San Francisco’s amazing California Academy of Sciences with this early-access admission ticket. For one low price — a Viator Exclusive available nowhere else — skip the lines and enjoy entry one hour earlier than the general public, a privilege normally reserved for annual members of the Academy. Then wander about the aquarium, planetarium, natural history museum and 4-story rainforest, all under one roof. With so much to explore, you’ll appreciate the crowd-free hour of checking out all there is to see at your own pace.
