Groups of 15 (and more) people must make reservations two weeks in advance to receive a discounted admission rate of $5 per child (ages 2–17) and $7 per adult admission. Group admissions are scheduled on a first-come, first-served basis, are not scheduled on holidays, and do not include a guided tour. There must be at least one adult for every seven children. Call the Education Registrar at (925) 627-2913 or email email@example.com to reserve space for your group.
All weekday morning hours during the school year are reserved in advance for school and group programs.
