About Granite Peak (Montana)#
Granite Peak is the highest mountain in the U.S. state of Montana, with an elevation of 12,807 feet (3,904 metres). It is located in the Beartooth Range in south-central Montana.
The summit is sought by mountaineers as a technical high point rather than a simple hike - routes commonly involve class 3 to low-5th-class moves, glaciers or permanent snow patches on some approaches, and significant route finding. Climbs are most commonly attempted in mid-summer when snow conditions are more stable.
The peak sits within the rugged Beartooth alpine landscape and is approached through alpine valleys and cirques; access typically uses trailheads in the surrounding national forest and wilderness areas.
Nearest towns and trailheads are in the broader south-central Montana region; approaches often require a full day or more of travel into alpine terrain before the ascent.
