Ptarmigan Peak - 12.0 Miles Round-Trip
Ptarmigan Peak (12,498') straddles the Summit County - Grand County line in the Ptarmigan Peak Wilderness near Silverthorne CO. This strenuous trail climbs over 3300' in 6 miles to a broad, flat summit with panoramic views across the Williams Fork, Gore and Ten Mile ranges. Visible peaks include Buffalo Mountain, Red Peak, Grays Peak, Torreys Peak and Longs Peak.
The trail heads north from the parking lot to a private road @ .1 miles. Turn left and walk 100 yards up the road to a sign for the Ptarmigan Trail pointing right.
The Ptarmigan Trail crosses a sagebrush hillside to a Ptarmigan Peak Wilderness Information Board (.7 miles : 9,617'); note the official boundary is still 3.7 miles and 1890' up from this point.
It drops under power lines (1.0 miles : 9,560') and rises across two small streams into a dense aspen forest for the next mile. The trail briefly opens with views of Buffalo Mountain and Red Peak before re-entering timber to the Angler Trail junction (2.0 miles : 9,868').
The trail continues north on a steady climb through 10,000' as aspen cede to spruce and fir. Grades steepen through 3.0 miles (10,425') on a northwest bend toward the summit. It crosses 11,000' (3.75 miles) and reaches treeline at the Ptarmigan Peak Wilderness Boundary (4.4 miles : 11,500').
The trail heads northwest across open tundra with exceptional views to the Ptarmigan Pass split (4.9 miles : 11,888'). Keep straight to the Ute Peak Trail - Ptarmigan Trail split (6.0 miles), and follow signs .1 mile up to the Ptarmigan Peak summit (6.1 miles : 12,498').
- Ptarmigan Peak Wilderness is adjacent to the Eagles Nest Wilderness, but just 1/6 its size (13,175 vs. 82,484 acres). Elevations in the Ptarmigan Peak Wilderness range 9,127' - 12,757'.
- The last 1 - 2 miles of the Ptarmigan Trail are above treeline. Anticipate varied weather conditions and get below treeline before storms develop. The summit approach is relatively rock-free compared to others in the area.
- Past the turn off to the Ptarmigan Peak summit, the Ptarmigan Trail becomes the Ute Peak Trail which continues north along the spine of the Williams Fork Mountain Range. There are very few trails that enter the Ptarmigan Peak Wilderness - but all of them connect with the Ute Peak Trail.
