The trailhead is at a large signed parking lot that is located on the north side of Highway 150 6.5 miles east of Kamas. This trailhead is accessible year-round.
Yellow Pine Creek.
From the trailhead, the trail first heads east across a stream before reaching Yellow Pine Creek after half a mile. The trail climbs slowly at first and then steepens at its northern end. All stream crossings are bridged on the lower section of the trail.
After about three miles from the trailhead a spur trail heads northwest to Yellow Pine Lakes. The spur trail is used more than the main trail. Turn right here. The trail can be hard to follow and is steep in places. In another 1.5 miles from the junction, the saddle between Yellow Pine Creek and Box Canyon is reached.
The summit of Duke Mountain is reached by heading along the ridge west for about a mile to the summit. There is some very minor scrambling. Enjoy the fine views of the Wasatch Range and Western Uintas from the summit.
The total round-trip distance is 11 miles with 3500 feet elevation gain.
Yellow Pine Lakes.
A good pair of boots is needed.
