Granite Peak (Montana)

Mountain Montana's highest peak and technical climbing objective

Montana’s highest peak and a longstanding objective for serious climbers, known for technical routes and variable alpine conditions. Mountaineers attempt Granite Peak for its challenging rock, route-finding and high-elevation exposure.

Main image

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.

  • Elevation: At 12,807 feet (3,904 metres) it is the highest point in the U.S. state of Montana.
  • Climbing notes: The peak is regarded as a technically challenging state high point, requiring route finding, scrambling and occasional roped climbing depending on conditions.
