Walker Valley / Humps and Bumps (87.1 miles away)
Mount Vernon, Washington
South Fork is a pretty straightforward gravel road. Expect large potholes, separated apart, to be more like speed bumps than danger to your wheels. It's a pretty lowland forest drive with a couple of dispersed campsites, with a sizeable one at the end. Arrive early if you plan on camping due to the ease of access—it fills up fast!
