Came across one of the best routes tonight while out for a cruise with a couple other cars. Luckily I had my laptop and GPS running so I can snag a screen shot for you guys.
It's out in the Abbotsford area.
There are a couple ways you can do this but the way we went was to start East-bound on Clayburn Road and continue until you hit Sumas Mountain Road. Turn left so you're going up the mountain via Upper Sumas Mountain Road. It will eventually turn into a gravel road (which is an awesome route for off-roading, btw). At which point, turn around and just follow it until it turns from Upper Sumas Mountain Road into Sumas Mountain Road. Eventually you'll get to an intersection it meets up with Atkinson Road. Turn right and you'll find yourself on Lower Sumas Mountain Road. This stretch is the absolute cherry of this route. Zero traffic on a near switch-back route on the mountain side. It's a bloody amazing run.
I've got some more routes marked out on my GPS for future exploring this week. Now that it's supposed to be relatively nice (great, I just jinxed it, didn't I?), some of these mountain passes should be pretty dry at night.
I'll keep you all posted with routes when they happen.
