Mount Langley via Cottonwood Lakes and New Army Pass Trail

The ideal time to hike this trail is typically from late spring to early fall, roughly May through October, when the passes are generally free of snow. However, conditions can vary, and it's always wise to check weather forecasts and trail reports before you go. Winter hiking is possible but requires specialized gear and experience.

Day hikers generally do not need a permit for this route. However, if you plan to camp overnight, an Inyo National Forest Wilderness permit is required. These permits are subject to a quota system from May through November and can be obtained through recreation.gov. It's crucial to secure your permit well in advance if you intend to backpack.

Yes, the trail is generally dog-friendly, but dogs must be kept on a leash. Please remember to pack out all pet waste and ensure your dog is prepared for the high altitude and strenuous conditions, just like you are.

The trail typically begins at Horseshoe Meadows, which is located at an elevation of around 10,000 feet. There is parking available at the trailhead. Given the popularity of the area, especially during peak season, it's advisable to arrive early to secure a spot.

The terrain varies significantly. You'll start with a gradual climb through forests and meadows, passing picturesque alpine lakes like Long Lake. As you ascend above 11,000 feet, the landscape becomes more stark and rocky, often described as having a "moonlike quality." The final push to the Mount Langley summit involves a steeper, rockier path with some scrambling over loose rock and sand, though it remains non-technical (Class 1).

Yes, there are numerous opportunities for water replenishment from streams and lakes along the way, particularly in the Cottonwood Lakes Campground area. It is highly recommended to refill your water at High Lake, as it is generally the last reliable source before the final push to the summit.

Beyond the stunning alpine lakes, you'll traverse New Army Pass, offering expansive views. The summit of Mount Langley itself provides sweeping vistas of the Sierra Nevada, including a distant view of Mount Whitney to the north. You'll also pass near Old Army Pass, another notable mountain pass in the area.

While some highly conditioned hikers attempt it as a grueling single-day hike, most people complete this challenging route as a 2 to 3-day backpacking trip. This allows for better acclimation to the high altitude and provides a more enjoyable experience, often with camping near the Cottonwood Lakes or Long Lake.

Yes, the route primarily follows sections of the New Army Pass Trail and the Cottonwood Lakes Trail. It also briefly intersects with the Mount Langley Trail, Golden Trout Camp Trail, and the South Fork Cottonwood Creek Trail.

Hikers can choose between New Army Pass and Old Army Pass. New Army Pass is generally preferred as it is more maintained, features easier switchbacks, and is safer, especially when snow is present. Old Army Pass is steeper, less maintained, and not advisable during snowy or icy conditions, though it can offer a slightly shorter route.

The diverse ecosystems along the trail offer opportunities to spot various wildlife. Keep an eye out for marmots, pikas, and mule deer, especially in the meadows and higher elevations. You might also encounter a variety of bird species.
