Directions
From the Darrington Ranger District office, take Highway 530 west six miles to the Whitehorse store. Turn left (south) on the mine road and follow it for 0.75 mile to the bridge over Moose Creek, which is closed to vehicles.
Notes
Walk across the old road bridge and steep road for 1.75 miles to reach the trailhead on the right. This old mining trail is used primarily by climbers seeking the summit of Whitehorse Mountain. Only the first 1.4 miles of the trail is periodically maintained. Above this, the route rapidly degenerates into a very steep and sometimes muddy way-trail, then into thick brush until no evidence of a trail remains. This trail enters Boulder River Wilderness.
Only experienced mountaineers should venture beyond here. Even the maintained part of the trail is steep enough to tax the cardiovascular system of climbers and hardy hikers. The trail offers glimpses of the Stillaguamish Valley and views of Round Mountain and Segelsen Ridge with Mt. Baker dominating the northernmost views.
