Near Edson (west of the city) can be good. Personally have not hunted there in a few years, but it was good from what I recall.
I usually head North of Athabasca, there's some good logging roads in there. Was able to harvest 5 Ruffies yesterday (opening day)!
Usually the hunting gets a bit better after a couple freezes as the ground bush starts to die off. Makes it significantly easier to see them. Pro tip: go right after a small snowfall as that REALLY makes it easy
Good luck!
