Home to nearly 60,000 live animals, a star-studded 75-foot planetarium, and a lush rainforest inside a 4-story glass sphere, the California Academy of Sciences is a microcosm of our marvelous world—and no two visits are ever the same. Become a member to add science, wonder, and inspiration to your daily life, every day of the year.
Academy members enjoy free Daytime Admission 365 days a year—which means extra quality time with Claude and our African penguins. Plus, membership can pay for itself in as few as two visits.
Reward your curiosity with exclusive programs all year long, from mind-expanding member talks and exciting animal feedings to sneak peeks at all-new exhibits. Experience science serenity twice a week at Tuesday Member Hour (8:30-9:30 am) and Jerry Hume Sunday Member Hour (10-11 am).
Free admission is just the beginning. Academy members receive 10% off at our stores and restaurants and on sleepovers and birthday parties, and 20% off VIP Tours, lectures, and NightLife. Save time at the door, too, with a dedicated member entrance.
Science is for everyone. We offer a variety of ways to make membership more accessible, including monthly payment plans as low as $6 and $49 memberships for EBT/CalFresh, WIC, Lifeline Pass, and Medi-Cal cardholders.
