The Southwest Ridge is the classic and most established climbing line on Ama Dablam. It is a sustained alpine route combining steep snow, rock, and mixed climbing on a very exposed ridge. The route is famous for its technical sections, especially the Grey Tower and the upper rock-and-ice steps. Objective hazards include rockfall, avalanche danger on the lower slopes, and severe exposure to wind and weather. It is generally climbed from a high camp on the ridge, with a long summit day from that camp. This is the standard route described in major Himalayan climbing references for the peak.
