Groups of 15–35 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 eight children. Call the education registrar at 925-627-2913 or email firstname.lastname@example.org to reserve space for your group.
All weekday morning hours during the school year are reserved in advance for school and group programs.
