The climb on this peak is both on rock and ice. A high level of technical skill, physical fitness and acclimatization is required. The approach to basecamp is via Skardu and takes about a week's trekking on Baltoro Glacier. An expedition to Gasherbrum II provides a more complete mountaineering experience than the commonly guided Tibetan 8000m peaks (Shishapangma & Cho Oyu) which can be reached by jeep roads.The walk to Gasherbrum II base camp along the Baltoro glacier has been described as one of the best treks in the world.
