California Academy of Sciences

Four Worlds Under One Roof

What makes the Academy unlike any other cultural attraction is the sheer variety packed into a single building. The Osher Rainforest is one of the largest indoor rainforests on Earth—a glass-enclosed sphere that replicates every layer of a tropical forest, from the flooded understory where giant Amazonian arapaima glide beneath your feet to the upper canopy where blue-and-yellow macaws and golden-headed manikins perch among free-flying butterflies. More than 250 exotic birds and thousands of butterflies live here, with a dedicated emergence chamber where visitors can watch new butterflies unfurl their wings each day.↗↗

Below the rainforest, the Steinhart Aquarium plunges you into ocean worlds. Its crown jewel is the Philippine Coral Reef, the deepest living coral reef tank on Earth—a 25-foot-deep, 212,000-gallon habitat where reef fish dart through forests of coral while giant rays sail overhead. Elsewhere in the aquarium, you can face a giant Pacific octopus adorned with sunflower sea stars, wade through the Amazon Flooded Forest Tunnel where river turtles paddle above your head, or get nose-to-nose with Methuselah, a nearly 100-year-old aquarium fish who reportedly enjoys belly rubs.↗↗

The Morrison Planetarium's 75-foot all-digital dome is one of the largest of its kind in the world. Current shows include Expedition Reef, which takes you diving into the ocean's most vibrant marine ecosystems, and Timescapes, an all-new production exploring California's geological past and imagined future. Shows fill quickly—reserving a seat upon arrival at the planetarium kiosk is a smart first move.↗↗

The Kimball Natural History Museum rounds out the experience with galleries that range from the Tusher African Hall's dramatic wildlife dioramas and penguin habitat to the Shake House, where an earthquake simulator recreates the ground-shaking violence of California's 1906 and 1989 quakes. Gems and Minerals Unearthed showcases nearly 400 dazzling specimens, while Hidden Wonders peeks into the Academy's staggering 46-million-specimen research collection—800 curated highlights including a saber-toothed cat fossil from the La Brea Tar Pits.↗↗

A Living Roof You Can Walk On

Before or after your indoor adventures, step outside onto the Academy's 2.5-acre living roof—a gently rolling landscape covered in 1.7 million native California plants and dotted with hundreds of solar panels. It serves as an oasis for birds, butterflies, and pollinators right in the heart of Golden Gate Park. The roof is a testament to the building's award-winning sustainable design and offers a unique elevated vantage point over the park's Music Concourse. For a deeper look, the Academy offers VIP tours that take you behind the scenes of the roof and other restricted spaces.↗↗

Best Times and Insider Tips

Timing your visit around scheduled programs elevates the experience considerably. African penguin feedings at 10:30 a.m. and 3 p.m. daily draw delighted crowds to the Tusher African Hall; arrive a few minutes early for a good view. Scuba demonstrations at the Philippine Coral Reef run at 11:30 a.m. and 1 p.m., offering a mesmerizing perspective on the reef from inside the tank.↗

For families with young children, the Wilson Family Nature Lab on the third floor is a reimagined discovery hub with touchable specimens, science games, and staff ready to answer curious questions. Outdoors, the Wander Woods playspace lets kids walk on giant logs, navigate a tree-laden maze, and build dens from natural materials. The Children's Eel Garden in the aquarium is another hands-on favorite—hold still and shy spotted eels will poke their heads from their burrows.↗

If you're in San Francisco on a Thursday evening, consider NightLife (6–10 p.m., 21+ with ID): the Academy transforms into a venue with live entertainment, special animal encounters, creative cocktails, and an adults-only twist on the daytime exhibits.↗↗

Planning Your Visit

The Academy is open Monday through Saturday from 9:30 a.m. to 5 p.m. and Sunday from 11 a.m. to 5 p.m. Last entry is at 4 p.m. Admission includes all exhibits for a single price: adults $49 (or $55 during peak periods including summer and holidays), youth $45–$49, children $39–$45, and age 2 and under free. A new Anytime Admission ($59) offers flexible visits year-round with skip-the-line access to the planetarium, rainforest, and Shake House. EBT cardholders can enter for $5.↗

Getting advance tickets is recommended, especially during peak season. The Academy participates in the San Francisco CityPASS, which bundles admission with three other top attractions and saves up to 45%. Inside the museum, the Academy Cafe offers grab-and-go meals and plant-based options, while the Terrace Restaurant in the West Garden provides a more upscale dining experience with locally sourced ingredients on weekends and holidays.↗↗

Located at 55 Music Concourse Drive in Golden Gate Park, the Academy is wheelchair accessible throughout and offers paid parking lots, garages, and free street parking in the surrounding area. The phone number for inquiries is (415) 379-8000.↗

A Museum That Does Science

What separates the California Academy of Sciences from a typical tourist attraction is its active research mission. The institution employs over 100 scientists who conduct fieldwork and expeditions worldwide, contributing new species discoveries and conservation research to global knowledge. The 46-million-specimen collection housed here isn't just a vault—it's a working research library that shapes our understanding of biodiversity, climate change, and evolution. When you visit, you're walking through the same halls where scientists study the natural world, and their latest discoveries regularly surface in new exhibits and programs.↗↗
