New Army Pass Trail

Overview

New Army Pass is a high, hard-earned gateway into the Sierra high country. Most hikers experience it as part of the Cottonwood Pass – New Army Pass loop from Horseshoe Meadow, a strenuous 22.7-mile total route with roughly 3,674 feet of elevation gain and about 10 hours 20 minutes of moving time. Expect long miles at altitude and a steep, no‑nonsense climb to the pass itself.

What You’ll See

This route strings together broad alpine basins and classic high-Sierra scenery: rugged granite, glacially carved cirques, and a constellation of lakes that keep the days visually rich and water sources frequent. Cresting New Army Pass delivers the money views—panoramas across serrated Sierra ridgelines. Campers regularly rave about the night sky out here thanks to elevation and low light pollution.

Difficulty and Who It’s For

Make no mistake: the ascent to the pass is “no joke.” The grade turns on, and at elevation it hits harder than similar climbs down low. Strong day hikers and backpackers who enjoy big, committing days will love it; newer high-altitude hikers should build in extra time or plan an overnight. Icy sections can linger on the higher, shaded portions—especially early in the season—so traction and caution may be necessary.

Best Time to Hike

Aim for summer into early fall—typically July through September—after snow has melted off the pass. Outside that window, the route may be snowbound and require mountaineering skills and equipment. Start early for cooler temps and steadier footing on any residual morning ice. If you’re out overnight, clear summer nights reward you with stellar stargazing.

Logistics

Begin from Horseshoe Meadow (either the Cottonwood Lakes or Cottonwood Pass trailheads). Parking is generally straightforward, and you’ll find amenities at the trailhead area like bathrooms, bear boxes, and even a water spigot. Water is commonly available along the route near lakes and streams, but you’ll need to filter.

Tips and Essentials

• Acclimatize if you’re coming from low elevation—spending a night at Horseshoe Meadow before tackling the pass can make or break the day.
• Weather shifts fast at altitude: pack layers, wind/rain protection, sun gear, and be prepared to turn around if ice or storms make the pass unsafe.
• Wilderness permits are required for overnight travel. Plan and reserve ahead during peak season.
• Pets are not allowed once you enter the national park; only service animals are permitted. Plan route and logistics accordingly.
• Mosquitoes can show up near water; bring repellent and consider long sleeves at dusk.
