Olympic National Forest is making a trail network in the far NE corner of the Olympic Mountains, often by converting a logging road into a trail. This is an example. The trailhead is on Road 28 at the same spot as the Mt. Zion trailhead, about two miles northwest of Bon Jon Pass. There is a new parking lot and toilet, and a Northwest Forest Pass is required. The FS website has a description and a map.
The trail starts downhill immediately on an old road, then is on new trail for a bit. Eventually the trail pops out onto more closed roads and winds down to Gold Creek. According to my old ONF map, the road along Gold Creek was once FR #28, but it was closed and that designation was assigned to the road higher up the hillside.
Anyway, from the Gold Creek crossing the trail continues uphill in a westerly direction on an old road. After a long mile the trail rounds the nose of the ridge and turns south, descending a bit. There are good views into the Upper Dungeness drainage from here. The walking up to about the five mile point is quite easy.
After five miles, maintenance has apparently ceased. The alder closes in and there are blackberry bushes to contend with as well. Once I started getting into soaking wet alder, I decided that was enough brush bashing for one day and turned back, about six miles in.
This trail is the route of the Pacific Northwest Trail and deserves a little more maintenance. In another two miles, according to the FS map and also the maps available at pnt.org, the road/trail intersects the Gold Creek trail and continues south to the Tubal Cain Mine trail. Like many of the trails in this area, it is relatively close to Seattle and would make an excellent shoulder season trail.
