The California Academy of Sciences in San Francisco is a combined natural history museum, aquarium, planetarium, and living rainforest housed in a single purpose-built facility in Golden Gate Park. The institution traces its origins to the mid-19th century and reopened in a new, sustainable building in 2008.

Key visitor attractions include a multi-story rainforest dome, the Steinhart Aquarium with marine and freshwater habitats, and the Morrison Planetarium offering astronomy programs. Exhibits integrate live animals, specimens, and interactive interpretive displays focused on biodiversity, earth systems and conservation.

The 2008 building features a planted living roof, open exhibition spaces, and sustainability systems designed to reduce energy use and showcase green architecture, while supporting the Academy’s research and public education missions.

Located in Golden Gate Park on San Francisco’s West Side, the museum is walkable from the park’s main entrances and well served by city transit.

  • Building and living roof: The Academy's 2008 building, designed by Renzo Piano, features a 2.5-acre living roof and was constructed to combine museum, aquarium, planetarium and rainforest under one green, LEED-certified roof.

What to See #

  • Osher Rainforest: A coral- and glass-enclosed rainforest dome that rises through the center of the building and houses live tropical plants, birds, and other small animals in a multi-story environment.
  • Steinhart Aquarium: A large public aquarium with coastal and reef habitats, including touch tanks and walk-through exhibits that display marine and estuarine species.
  • Morrison Planetarium: A projection-based planetarium offering astronomy shows and educational programming operated as part of the museum complex.

Tips for Visiting California Academy of Sciences #

  • Reserve timed-entry tickets in advance-especially on weekends and holidays-since the Academy limits capacity for the aquarium, rainforest and planetarium experiences.
  • Plan your visit around scheduled events: aquarium feedings, planetarium shows and scheduled rainforest walkthroughs have limited seats, so pick showtimes when you buy tickets to avoid long waits or missing them.
  • Start on the top floor rainforest and work down through the exhibits to avoid peak traffic jams around the aquarium and to take advantage of quieter viewing in the morning or late afternoon.
