Mount Langley via New Army Pass

Mount Langley via New Army Pass is a 23.3-mile out-and-back route that takes you to the top of Mount Langley (14,032’), the ninth highest peak in California. This route, the most common and easily accessible approach, starts from the Horseshoe Meadows trailhead and uses the Cottonwood Lakes Trail and New Army Pass to reach the summit. The hike offers stunning alpine scenery, including meadows, crystal-clear lakes, and sweeping granite landscapes. Along the way, hikers pass through groves of foxtail pines, climb craggy ridgelines, and enjoy breathtaking summit views.

Mount Langley, one of California’s fourteeners, is highly sought after for its non-technical ascent, requiring no special gear or climbing skills. While challenging, it provides a rewarding adventure for experienced hikers, trail runners, backpackers and novice peak baggers. 

This route is described as a strenuous day hike but can also be done as an overnight backpacking trip (overnight camping requires a backcountry permit).

DESCRIPTION
Starting from the Cottonwood Lakes Trailhead, the route begins with a gentle climb through a forest of foxtail pines and meadows, leading to the scenic Cottonwood Lakes Basin. From here, follow the trail toward New Army Pass, which offers a well-graded yet strenuous ascent. As you reach the pass, you’ll be rewarded with sweeping views of the Sierra Nevada before descending slightly onto a broad plateau.

The trail then turns northward toward Mount Langley, where it transitions into a steeper, rockier path as it nears the summit. The final push involves some scrambling over loose rock and sand, but it remains non-technical. From the summit, enjoy panoramic views of the Sierra, with Mount Whitney visible to the north. After soaking in the views, retrace your steps down New Army Pass, passing through the Cottonwood Lakes area as you make your way back to the trailhead.

Best Season: July–October (depending on snow conditions)

FLORA AND FAUNA
The trail traverses diverse ecosystems, ranging from alpine meadows to high desert terrain. Along the way, you'll encounter wildflowers, lupines, and a variety of alpine plants. Wildlife sightings include marmots, pikas, mule deer, and various bird species. The area is also home to black bears, so proper food storage is essential to keep your gear safe and minimize human-wildlife interactions.
PERMITS AND REGULATIONS
Permits are required for overnight camping in the Inyo National Forest and can be obtained from www.recreation.gov. Reservations are recommended during peak season. Practice Leave No Trace principles to preserve the natural beauty of the area.

SAFETY AND CONSIDERATIONS

• Prepare yourself for high elevation hiking, as most of the route is above 10,000 feet.

• Weather in the Sierra can change rapidly; pack layers and be prepared for varying conditions.

• Carry sufficient water, food, and navigation tools (map, compass, GPS).

PARKING

Ample parking is available at the Cottonwood Lakes Trailhead. However, as this is a popular starting point for entering the High Sierra, it's best to arrive early, particularly on weekends and during peak season, to ensure you secure a spot.
