Old Army Pass Trail is a 1.2-mile point-to-point climb one way, from the end of the maintained Cottonwood Lakes Trail in the upper basin to Old Army Pass. The mapped line measures about 1.18 miles; another published route description gives 1.7, and no official track settles the difference. Treat the mileage as approximate. This is the pass segment only, not the approach from Horseshoe Meadows or a Mount Langley summit hike. If the pass is your turnaround, retrace the line for about 2.4 miles round trip, plus the approach.
The abandoned tread climbs through steep switchbacks, then picks over or around large boulders to the crest. Allow about two hours for the climb from the upper basin; this estimate doesn’t include getting there or walking back. The route starts above 11,000 feet and reaches almost 12,000, so the short distance feels harder than it looks. Snow can make Old Army Pass treacherous, especially early in the season.
From the crest, look back over Cottonwood Lakes 4 and 5 and their surrounding meadows. That basin view is the payoff. The trail ends at the pass; the westbound Army Pass route and the Mount Langley summit itinerary are separate continuations, not part of the distance above.
Park at the Cottonwood Lakes Trailhead at Horseshoe Meadows, at the end of Horseshoe Meadow Road. Follow the maintained Cottonwood Lakes Trail into the upper basin; reaching Old Army Pass takes a substantial approach, which is outside the 1.2 miles above. The road typically closes around November through May for snow. Inyo National Forest lists a 60-person daily quota for Cottonwood Lakes access from May 1 through November 1. Day hikes don’t need a wilderness permit; overnight trips do year-round, so check the quota before setting out.
The approach starts on Inyo National Forest land and the pass is at Sequoia’s edge. Inyo’s rules allow pets on trips that stay in the forest, but pets are prohibited on National Park trails and on wilderness trips entering Sequoia. Leave pets behind if you plan to cross the pass into the park.
