Nuptse (7,879m) Lhotse (8,501m),in the west to Lhotse Middle Peak (8,410m) and Lhotse Shar (8,383m), Makalu (8475m) in the east, Baruntse and Amadablam in the south are seen. Considering the growing interests in climbing Island Peak is as part of training and preparation for an extensive mountaineering expedition in Nepal as the Island Peak stands for the purpose of acclimatization before heading to bigger mountain climbing.
The normal route for climbing Island Peak is South East Flank & South-West Ridge. Normally, the base camp is set at Pareshaya Gyab (5,087m), between Imja Tse and the lateral moraine of the Imja Glacier. Proper care should be taken to avoid the possible avalanche in the event of heavy snow fall. For some people reaching to the summit from the base camp is a day activity. However, most of the climbers prefer alpine style camping at high camp which adds the joy of climbing and also helps a safe ascent.
