About Mount Muir
Mount Muir is a peak on the Mount Whitney massif in the Sierra Nevada of California, United States. It stands at roughly 13,000 feet (about 3,960 metres) and lies immediately adjacent to the Mount Whitney area.
A common objective for experienced hikers and mountaineers, the summit is reached by scrambling from the Mount Whitney Trail and nearby ridgelines; the final slopes are exposed and require careful movement. The peak offers close views of Mount Whitney and the surrounding high Sierra crests.
The peak is named for naturalist John Muir and forms part of the high-elevation alpine landscape long used for mountaineering and high-country travel. It sits near the boundary of Sequoia National Park and the Inyo National Forest.
Geographically it occupies the Sierra Nevada crest in eastern California, just south of the Mount Whitney summit and accessible from the Whitney Portal trailhead on the western side of the range.
- Elevation: Reaches roughly 13,000 feet (about 3,960 metres), making it one of the higher subsidiary summits on the Mount Whitney massif.
- Access: Most approaches begin from the Whitney Portal trailhead and the final sections require exposed scrambling; parties should be comfortable with off-trail routefinding and exposure.

Tips for Visiting Mount Muir
- If approaching from the Whitney area, allow extra time on the Mount Whitney Trail-Mount Muir is often a high-point on that route.
- Carry ice axe and crampons in shoulder seasons-the ridge can retain snow and ice well into summer.
- Expect exposure-the final ridge to the summit is narrow and requires comfort on rock and mixed terrain.
