Mountaineering Routes · Gasherbrum I

This is the standard and best-known route on Gasherbrum I, first climbed in 1958 by an American team via the Southwest Ridge. It is a very high-altitude, technically serious route with sustained snow, ice, and mixed climbing, plus major objective hazards from weather and avalanche conditions.

The Japanese Route is a documented alternative line on Gasherbrum I, known for its steep and demanding West Face climbing. It is significantly more difficult and committing than the normal route, with sustained technical difficulties at extreme altitude.
