One of the more prominent peaks in the Tetons, Nez Perce towers over the valley south of the Middle and Grand Teton. When approaching via Garnet Canyon, the peak is to your left (south) and makes up a large portion of the skyline. There are several technical climbs on just about every aspect, though some suffer from poor rock quality.
The classic route on the peak is the South Ridge. Just about every route could be climbed in a (long) day from the valley, but a start from within Garnet Canyon (either the Platforms or Meadows) makes for a less grueling day.
Hike up Garnet Canyon from the Lupine Meadows trailhead. Depending on your chosen route, ascend a couloir above the Platforms or continue up the drainage angling N of the Middle Teton.
