Field Trips

How to sign up for a field trip

- Attendees can sign up for trips before and during the Friday evening lecture and also on Saturday and Sunday at the festival information booth outside the John Wesley Powell River History Museum.
- The festival booth will open at 5pm before the Friday evening lecture, and again at 9am on both Saturday and Sunday.
- Field trip sign-ups are first come, first serve and must be done in-person during the festival. There's no way to sign up in advance.
- All field trips are half-day to full-day trips. Group size for each trip is approximately 25 people. If there is a trip you are particularly excited about, we recommend coming to the Friday evening lecture to sign up early.
- Field trip leaders will meet their group in the museum parking lot. Prepare to caravan to field trip sites in your own vehicle. Many trips involve driving on dirt roads. Descriptions of road conditions can be found in each trip description. Pack plenty of water and a sack lunch, and fill your gas tank ahead of time. Wear comfortable clothing and bring sun protection.
- Send all field trip questions to [email protected]. Staff at the John Wesley Powell River History Museum will not be able to answer any questions. The Museum does not organize the festival, they are just our gracious hosts!
