The signed trailhead (42.68777, -124.43935) is located at a large gravel pullout on the south side of Highway 101 about 8.6 kilometres south of Port Orford or 22.9 kilometres north of Nesika Beach. There are no facilities at the trailhead, but vault toilets can be found at the park's day use area about 1.8 kilometres to the east along the highway.
From the trailhead, Zosia and I entered forest and began a gentle but steady climb up the easy-to-follow trail. About 1.5 kilometres in, the trail splits with the left branch winding up the eastern side of the mountain while the right branch climbs up the west ridge. We opted for the slightly longer eastern approach, and although the ascent was mostly straightforward, the very last section of trail just before the top was wiped out by a storm some time ago. As a result, the trail has been re-routed slightly to join up with the last part of the other trail coming up the west ridge. The re-routed trail is a bit rough in places, but it was nothing we could not handle. Upon reaching the partially open summit, we stopped for about half an hour before commencing our descent.
Zosia and I completed a traverse of 
       Humbug Mountain by descending the west ridge trail.  The trail was 
       in good shape all the way down to the split, and we had no issues 
       whatsoever hiking back to the trailhead. 
       Despite a general lack of views, the hike through the forest is still 
       enchanting.

        This is pretty much the only far-reaching view to speak 
       of on Humbug Mountain.
