Field trips to Trethewey House Heritage Site are approximately 90 minutes long and consist of two 45-minute programs of your choice from the selections below.  When classes arrive, students are split into two groups in order to make the experience and trip to the Heritage Site more personable and catered to individual student interests and class needs (and to help us be in accordance with load capacity in Trethewey House). Each group completes one program and then switches programs at the 45-minute mark. For more information and a list of our FAQ, please visit our School Programs FAQ.

Payment and form submission is due two weeks prior to the program. Failure to submit payment and/or completed booking forms may result in the cancellation of the booking.

PLEASE NOTE: The Trainwhistles and Schoolbells Outreach Program is not offered on site and is not available during field trips.



Sign up for our Trainwhistles and Schoolbells Outreach Program! Trainwhistles and Schoolbells is a standalone program and cannot be combined with other program offerings. Please note: An outreach booking is good for one class; outreach can not accommodate more than one class at a time.

Frequently Asked Questions

We are located near Mill Lake at 2313 Ware Street with access to the museum parking lot off of Alta Avenue.
Is there parking? Is it free?

There is parking, and yes it is free! If arriving by passenger vehicle, please park in the free museum parking lot off of Alta Avenue. If arriving by bus, please park the bus on the street and have your group walk through the parking lot to the Heritage Site.

Please assemble all students and program participants on the cement pad between Trethewey House and the Heritage Gallery and ring the buzzer by the office door to let us know you have arrived. We request that teachers divide their students into two equal groups and ensure that there are enough chaperones for both groups.

If the number of students attending the program changes before the booking date, please contact our Programs Manager at or 604-853-0313. The final number of students will be confirmed onsite at Trethewey House before the start of the program. Payment for all students must be received before the start of the program.

We recommend that each school class has a minimum of four chaperones (two for each group once the class is divided in half) to a maximum of eight chaperones total for load capacity reasons.

All chaperones are subject to the $5 tour fee.

We tailor each tour to the age of the class group. For that reason, we do not permit any kids or siblings not enrolled in the class to accompany school tours.

It is possible to leave the tour while it is in progress, but please note that anyone needing to step away from the group temporarily must be accompanied by a chaperone in order to be let back into Trethewey House as the building will be locked from the outside for security purposes.

We are located next to the Mill Lake trail loop, which loops around the entirety of Mill Lake and around which there are playgrounds and a lot of local fauna and wildlife. We are neighbours with the Abbotsford Arts Council and are located a walking distance (1.0 km) away from the Gur Sikh Temple. The Reach Gallery Museum (2.7 km) and the Mennonite Heritage Museum (3.6 km) are also nearby.

If you need to reschedule or cancel a program for any reason, please contact our Programs Manager at or 604-853-0313. Please note that payments for cancelled programs will not be refunded.


This program focuses on railroads and the history of local schooling to teach
