Under the Living Roof: Exploring the California Academy of Sciences
A living roof, penguins, rainforest and stars—science you can touch in Golden Gate Park.
You push open the glass doors into a warm, humid blur—the sound of distant water, the hush of spectators, a tropical chorus rising somewhere overhead. Sunlight, filtered through the sinuous green of a two-and-a-half-acre living roof, pools on the plaza outside. Inside, a penguin preens on a rocky outcrop while children press faces to the aquarium glass; above them, the Morrison Planetarium waits with a universe to unfold. This is the California Academy of Sciences, a place where museum, aquarium, planetarium and living rainforest converge in the heart of San Francisco’s Golden Gate Park.
Trail Wisdom
Buy timed-entry tickets
Reserve a specific entry time online to avoid long queues—weekends fill up fast.
Arrive early for quieter galleries
Morning visits mean fewer school groups and better photo opportunities at the aquarium and rainforest dome.
Layer up for humidity changes
Bring a light layer—the rainforest dome is warm and humid while other galleries can be cool.
Combine with Golden Gate Park
Leave time to stroll the living roof and then walk to the nearby de Young or the park’s west lawns.

Seasonal Guide
spring
Best for: blooming roof plantings, fewer tourists, mild weather for park strolls
Challenges: occasional rain, school field trips on weekdays
Spring brings native plants on the living roof into fresh growth; galleries are lively but not yet at summer capacity.
summer
Best for: extended park hours, family-friendly programming, special exhibits
Challenges: largest crowds, longer lines for planetarium shows
Summer is busy—book in advance and arrive early to avoid peak crowds and queueing.
fall
Best for: clearer skies for planetarium nights, pleasant park walks, moderate crowds
Challenges: shorter daylight hours, some seasonal exhibit changes
Fall is ideal: milder crowds and comfortable weather to combine the museum with Golden Gate Park outings.
winter
Best for: indoor programming, rainy-day plan B, education-focused events
Challenges: wet weather in the park, some outdoor roof access limited after storms
Winter weather makes the Academy a perfect indoor destination—expect a cozy, educational experience amid rainy San Francisco days.
