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.
