Hours of operation 2024

Well, that's just about it for 2024. The final show was the Lesco Pro Truck show on 21-Sept, and it was a HUGE success; lots of people on site and lots of visitors to our museum. The next event will be the Leduc Country Lights all through the month of December. The whole park will be lit up in a breathtaking display of thousands of lights covering 8 acres. Unfortunately, the EPHF Museum will not be open to visitors for this show. If, however, you are interested in a private tour, just leave a message on this website and we'll do our best to arrange a time for you to come out.
We'll open again in May 2025 for the Leduc West Spring Swap Meet, dates to be announced. Watch this space.
