I would recomend you join your local club the Skeena Valley Snowmobile Association. Their website is and they have an active facebook page as well under northwest bc snowmobilers. Good luck they have some awesome riding up there!
There's probably a dozen or so areas within an hour drive, 3 or so good ranges if you go up to Stewart and also a bunch of areas in Smithers/Hazelton area. Looks like a slow start this year. The sled club meets first Wednesday of every month at Denny's at 7:30.
Your welcome to come with us for some rides. Msg me your cell and can txt details...250-631-9104. I don't think i'm going to ride until we get a few good storms though. Looks like one is coming this weekend. It's looking like first week of December though.
