One ticket at the California Academy of Sciences gets you into an aquarium, a rainforest, a planetarium, and a natural history museum, which is part of why lines can back up fast on weekends — most visitors are trying to hit all four in one trip. It’s in Golden Gate Park at 55 Music Concourse Drive, and it’s open every day of the year.
What’s Actually Inside
The Steinhart Aquarium holds roughly 38,000–60,000 live animals across dozens of tanks, including the Philippine Coral Reef exhibit and a colony of African penguins fed twice daily. The Swamp is home to Claude, an albino alligator who’s been a fixture of the museum for years. The Osher Rainforest is a four-story glass dome you walk up through, ending with a glass elevator ride down through a simulated flooded Amazon exhibit. Morrison Planetarium runs multiple digital shows daily, included with admission, though seating is limited — check the show schedule and reserve a spot (via QR code in the lobby) as soon as you arrive rather than assuming you can walk in anytime. The Living Roof, planted with California native species, is visible and free to view from outside without a ticket if you just want a look.
Current Admission (check calacademy.org before you go, since these shift seasonally)
- Adult (19+): $49, $55 during peak periods (spring break, summer, holiday weekends, November–December holidays)
- Youth (13–18): $45, $49 peak
- Child (3–12): $39, $45 peak
- Ages 2 and under: free
- EBT cardholders: $5 (Museums for All program — must be purchased in person at the ticket window, not online)
If you’re visiting in summer, know you’re paying peak pricing. A San Francisco CityPASS can knock a meaningful amount off if you’re also planning to hit other major SF attractions on the same trip.
Practical Tips
- Book ahead, especially on weekends. The Academy gets genuinely crowded, and buying tickets online in advance avoids both the ticket-window line and the risk of a sellout on a popular day.
- There’s no on-site parking. The Music Concourse Garage nearby is paid; free street parking exists around Golden Gate Park but fills up quickly on weekends. Public transit into the park is often less of a hassle.
- Plan 3–4 hours if you want to see the aquarium, rainforest, planetarium, and natural history exhibits without rushing. Two hours is workable if you’re prioritizing just one or two sections.
- Thursday nights are adults-only. NightLife (21+) runs Thursday evenings with a bar, DJs, and full museum access, at roughly half the price of daytime admission — a different experience than a daytime family visit.
- Check for closures before you go. The Academy occasionally closes early or fully for private events on specific dates; the hours and admission page on calacademy.org lists any upcoming closures.
Bottom Line
Buy tickets online in advance, reserve your planetarium show time the moment you walk in, and budget half a day if you want to see everything. If cost is a concern, check whether you qualify for EBT admission or whether a CityPASS makes sense for your broader San Francisco itinerary before paying full peak-season price at the door.
