Snowshoe or cross-country ski on this road just below the Mount Baker Ski Area. This route is White Salmon Road, and is not related to Salmon Ridge or White Salmon Creek. Those are separate areas, slightly more advanced, and require a Sno-Park permit at the lot.
To explore White Salmon Road, simply walk up Forest Service Road 3075. As you hike, you'll crest the ridgeline, and then head down to the end of the road. Be aware of other trail users, as this is a national forest road.
Views from the road include Mount Shuksan and many of the snow-covered surrounding hills.
