The Academy recently opened a new facility in Golden Gate Park, a 400,000 square foot structure that houses an aquarium, a planetarium a natural history museum and a 4-story rainforest all under one roof. The new facility is also home to the Academy's staff of world-class scientists, an education department that provides a wide range of student and teacher services, and an extensive science library with over 26 million specimens and artifacts.
Dan's opinion:
Wikipedia excerpt:
The California Academy of Sciences is among the largest museums of natural history in the world. The academy began in 1853 as a learned society and still carries out a large amount of original research, with exhibits and education becoming significant endeavors of the museum during the twentieth century. Completely rebuilt in 2008, the building is among the newest natural history museums in the United States. The primary building in Golden Gate Park reopened on September 27, 2008.

We don't have any current exhibitions on file, most likely because we're still collecting listings.

In the meantime, check out the CAS homepage or our exhibitions list for S.F.-wide exhibits.
