So I just finished looking at the maps of the area...All three routes will work but fuel is your biggest concern...unless you have large tank(s).
1st Option: You can go in north of the fraser (past PG and go right) but its a long drive on a main fsr and you end up at the same spot (fraser river bridge) as if you go in via upper fraser....NOT GOOD
2nd Option: You can go out past purden lake which may be open to grab fuel (this is important), but I am not sure if the gas pumps are open in winter...I'll ask this week when we go there for dinner. BUT the fsr is WAY past purden (1hr+) on thw highway...then back up the fsr (sande creek?) but again you end up at the fraser river bridge.(SAME PLACE AS ABOVE).
3rd Option: Drive to pg,go east on hwy 16...left on upper fraser rd (giscome hwy on some maps), left on ferndale rd...stop for beers and fire and sleep...back onto upper fraser,stop at willow river (LAST GAS STATION/GENERAL STORE), keep heading down the upper fraser to the east until you cross the fraser river bridge (
pavement ends) and then go to the left...stay on the pass lake road until you hit the macgregor river (campground available) cross the bridge and go left or right WELCOME TO 7-18!!!
Right will come to a dead end a ways down the road but you may be able to hike/quad in further...
Left will take you around the mountain range you are facing (Dezaiko range) as you cross the bridge and put you in the next valley over...along with access to some other areas, but becareful not to croos into the other ajoining mu's (the bounday's are usually marked but don't count on it...
I'm gonna see about a drive up that area anyhow so if I remember I'll post up what I see...Just remember YOU ARE VERY REMOTE even though its road accesable...even my house will be a good 2 hours away... that said you will probably see folks around...just not many. I don't know muchabout the hunting pressure in that area...I'm new here..
