FIELD TRIP Registration & Fees


Morning and full-day field trips are available Monday through Friday throughout the school year, including the winter months, with flexible hours and a maximum of 60 students per day, with the exception of our Early Childhood and full-day Invasive Species programs, which are limited to 30 students per day.

We also have a limited capacity for afternoon programs, which are offered throughout the year starting at 12:30 on Tuesdays and Thursdays, with a maximum of 30 students per day.

Our schedule fills quickly, so please checkout our updated list of available dates before registering and try to plan your trips well ahead of time. Groups of more than 10 students must be scheduled at least three weeks in advance in order to recruit volunteers and reserve classroom space.

Registration for each school year begins in mid-August, check back then or email the Field Trip Coordinator to receive a notification when registration is available.


*We do not charge for chaperones, classroom aids, or teachers. and reduced-fee scholarships are available to Title 1 and Head Start Schools.

Your invoice will reflect the number of students you state during the registration process and is due 15 days after it is received.  A late fee of $35 will be applied if payment is not received 10 days after the invoice due date, unless alternate arrangements have been made in advance with the Field Trip Coordinator.  We can make adjustments to the number of students attending your field trip after an invoice has been issued, but please note that any such adjustments will include a $20 administrative fee. 




If for some reason you are unable to come for your field trip and cannot reschedule to a different date, we are able to issue a full refund if you cancel your registration more than 30 days before your field trip is scheduled.  Between 30 days and 1 week before the trip, cancellations will be refunded less a fee of $50.  Cancellations made less than 7 days before the trip are not eligible for a refund. 

Note that cancellations due to school closures or unsafe weather conditions (heavy wind, ice, snow) will get priority for rescheduling.  If no alternative date can be found, the field trip will be refunded in full.


If you have billing questions or concerns, please contact the Field Trip Coordinator.
