take the highway to edson then south to robb and head up the cadomin road (40). after you get to the rail road tracks overpass,about 8 or 9 kms, you hang a left on the pembina haul road( weyerhauser) follow that for about 40 or 45 kms, you will come to a " T " intersection, go right for a mile or so and ther will be 2 open areas, one has two levels to it on your right , and the other is right beside the river ( cardinal and ruby run together there) there is a kiosk(info sign ) unload and cross the river and thats the trail in to the Ruby falls.
Not that it matters now, you probably needed the info for the long weekend, but anyhoo here it goes.... from Drayton go down lodgepole highway, turn onto the elk river road, follow till you come to the pembina forks. turn left and follow till you hit the cardinal river road. turn right, follow through small boys camp, go slow they have very large trenches dug through the reserve...lol seriously!! follow road and you come to Grave Flats... Hope this helps, it's very easy!!
The roads to the staging area are clearly marked you cannot miss them, the only one not marked is when you get to grave flats. But after you go through small boys camp, just follow the road you'll come right to it.
quick refresh of the roads, hwy 620 past lodgepole,
RIGHT on ELK RIVER ROAD.
LEFT when you hit the PEMBINA FORKS.
RIGHT on the CARDINAL RIVER ROAD follow until you get to Grave Flats and you are there. Hope this helps
