The Carne Mountain Trail is 3.7 miles long, gains 3000 feet of elevation, and is primarily recreated by hikers and stock users. The trail starts 0.25 miles up Phelps Creek Trail #1511, and climbs switchbacks of moderate to steep grade through open forests for about 2.5 miles. The forest opens up to a small mountain basin at about 6100 feet, where there are many campsites and an easily-accessible stream. The trail continues beyond the basin, past the junction with Old Gib Trail #1528, and switchbacks up to the south ridge of Carne Mountain. This is also where the trail enters the Glacier Peak Wilderness. Hikers can follow the gentle ridge north to the top of Carne Mountain—which offers spectacular views of Glacier Peak and other breathtaking mountains—or can follow the trail as it switchbacks down the other side of the ridge and ends at Rock Creek Trail #1509 within Glacier Peak Wilderness.
