0 km: Start at the Richmond Lake trailhead and hike upward 170 m (570 ft.).
1.1 km: Richmond Lake. Hike along the northern shore on intermittent trail to the western tarn. From the tarn, make your way northwest through open subalpine, brush and meadows, gaining elevation to 2230 m (7,330 ft.) and angling right (north) as you climb.
3.6 km: Southern ridge of Nogalski Peak, N73500-E 57800. At the rocky ridge, turn right and hike along the broken bedrock, following intermittent trails to the summit.
4 km: Nogalski Peak, N73610-E58180, at 2270 m (7,450 ft.). Hike just past the cairn at the summit and look downhill on the left (north) for a safe and steep route down. There is only a short steep section to scramble down with adequate foot and hand holds. Scramble down 40 m (130 ft.) to the alpine grassy meadows below on the steep sidehill.
4.3 km: Hike the meadows down to the top of a new rough-cut road up into the alpine, N73751-E58311. Hike down the steep road to Perry Pass.
5.3 km: Perry Pass, N74415-E58600, at 1985 m (6,513 ft.). A large, well-built, new road slashes across the pass and continues above Gold Run Lake. Hike right (east) on the road. This new road heads over Perry Pass to the headwaters of Hellroaring Creek and appears to link with the road at the trailhead of Gold Run Lake.
6 km: Anywhere above Gold Run Lake, descend through the false azalea bushes and forest down to the lakeshore.
6.3 km: Gold Run Lake, N74100-E59200, at 1860 m (6,100 ft.). Turn left (east) at the lakeshore and follow the good trail down.
7.3 km: Gold Run trailhead, N74000-E60000. Hike the rough road downhill (south).
8 km: Richmond Lake trailhead and circuit complete.
