Cottonwood Lakes Loop

Cottonwood Lakes Loop is a 69 mile loop starting and ending at the Cottonwood Lakes Trailhead. This route takes you on a journey through the stunning landscapes of the Southern Sierra Nevada. This ambitious backpacking route traverses Cottonwood Lakes, New Army Pass, Siberian Pass, and Rock Creek Trails, before joining the iconic Pacific Crest Trail and High Sierra Trail. You’ll pass through diverse ecosystems, from subalpine meadows and pine forests to rugged alpine passes and pristine creeks, experiencing some of the most remote and serene wilderness in the region.

This demanding loop offers a fantastic mix of rugged terrain, serene wilderness, and unforgettable views, perfect for seasoned backpackers looking to experience the best of the Southern Sierra Nevada.

DESCRIPTION
Begin at Cottonwood Lakes Trailhead, following the Cottonwood Lakes Trail to New Army Pass. This gentle ascent winds through pine forests and meadows dotted with glacial lakes, with excellent views of Mount Langley.

Note: New Army Pass is steep and may retain snow early in the season, so plan for some exposure.

After summiting New Army Pass, enjoy sweeping views of the Sierra crest. Take a brief detour onto Siberian Pass Trail to descend into the Rock Creek drainage, surrounded by rugged peaks. Continue along Rock Creek Trail, passing through alpine meadows, until you connect with the Pacific Crest Trail (PCT). This section follows a relatively gentle stretch of the PCT, offering incredible Sierra wilderness views and frequent encounters with other hikers during peak season.

Leave the PCT to join the High Sierra Trail (HST) through Kern Canyon. After several miles, reach a junction and head east on the Golden Trout Creek Trail. Complete the loop by taking the Trail Pass Trail, which leads you back to the Cottonwood Lakes Trailhead.
