Thanks for your interest in visiting the Los Angeles Zoo with your school group! Please read the following information before booking your field trip.

Requirements

Special discounted admission prices are available with advance reservations ONLY for California school groups, short-termed as CSG, (registered with the California Department of Education). They can enjoy 10% off.

PLEASE NOTE:

Reservation blackout dates(限制日期) may apply to all groups at certain times of the year (e.g. holidays and spring break). If your group comes on a blackout date or has not made the necessary reservations before arriving at the Zoo, your group will be charged the regular admission fees.

Docent(讲解员)-Guided Tours

Our docent guides lead educational walking tours for students and their teachers, beginning at first grade. A limited number of docent-guided tours are available. There is no additional fee for a docent-guided tour, but you must book your tour at least two weeks in advance. Do not assume you have a guided tour booked until you have received a confirmation number and packet from the Los Angeles Zoo. On the day of your field trip, your group will need to arrive at least 30 minutes before the confirmed start time of your tour to check in. Make sure to tell Zoo staff upon your arrival that your group has a docent-guided tour. If you are more than 15 minutes late for your tour, it may be canceled.
