Being a member at The Nat is a three-course meal with dessert included. Every time I go, whether it's a random weekday or an evening event (the Secret Society of Adultologists nights are ridiculously fun), I find an opportunity to learn something new, talk to someone interesting, and be generally awed. - Kersten, 2026
Members enjoy a variety of exclusive events—from exhibition openings to our annual book club—plus discounts on public programs. See some of our upcoming events below.
During the fourth session of One Book, One Museum book club, we’ll be taking a closer look at nature’s “wet bugs”.
Nat members and Balboa Park Explorer passholders are invited to join us for exclusive early hours.
Where can I sign up to be a member? Join, renew, or give the gift of membership online, at the Admissions Desk, or by calling the Membership Department at 619.255.0275.
