Overview

New Army Pass is the classic high route out of Horseshoe Meadow: 4.8 miles past the Cottonwood Lakes to a 12,300-foot saddle beneath Cirque Peak, with Mount Langley's plateau beyond. It is the standard acclimatization trip for Whitney hopefuls and the gateway to Sequoia National Park's southern backcountry.

Highlights

  • Five alpine lakes strung beneath Cirque Peak on the approach
  • A 12,300-foot pass reached without any technical terrain
  • Mount Langley — California's southernmost 14er — as the obvious next objective
  • The Sequoia backcountry opening from the pass

  • Water: The Cottonwood Lakes chain; treat all water.

Weather forecast
