Head north through pine forests along Cottonwood Creek. Pass the junction with the New Army Pass Trail at 3.5 miles. The trail turns west and at around 4.5 miles you enter an open meadow with excellent views of the Sierra Crest ahead. Continue on and pass Cottonwood Lake Three on your left and then end at Cottonwood Lakes Four and Five.
There's great camping at Cottonwood Lake Number Five beneath Mount Langley.
The look up at Cirque Peak from the Cottonwood Lakes Trail can be utterly stunning.
