Scheduling & Permits

  • If you are scheduling this as a non-course related activity, please limit your group size to the default party size. The maximum party size is for use by course field trips only, and includes both students and instructors. Group size maximums do not reflect how course field trips are run (in smaller groups of students and instructors), but allow for course leaders to register the course in our system.
  • This route allows multiple bookings. Please check scheduled trips listed below in the "Activities" tab to see if there is another group already booked on the same day. If so, please coordinate with them to ensure you are carpooling and teaching at different areas.
  • If you are scheduling a course field trip, please contact our Member Services Team to confirm the field trip and any permitting regulations.
