Imja Tse, better known as Island Peak, is a mountain in Sagarmatha National Park of the Himalayas of eastern Nepal. The peak was named Island Peak in 1951 by Eric Shipton's party since it appears as an island in a sea of ice when viewed from Dingboche. The peak was later renamed in 1983 to Imja Tse but Island Peak remains the popular choice. The peak is actually an extension of the ridge coming down off the south end of Lhotse Shar.
Imja Tse is the most popular of Nepal's so-called trekking peaks given its difficulty (alpine PD+) and accessibility especially when supported by a climbing guide and is the most frequently climbed peak in the Himalaya.
To climb Island Peak, one has the option of starting from a base camp at 5,087 metres (16,690 ft) called Pareshaya Gyab and starting the climb between 2 and 3 am. Another popular option is to ascend to High Camp at around 5,600 metres (18,400 ft) to reduce the amount of effort and time needed for summit day. However, adequate water supply and concerns about sleeping at a higher altitude may dictate starting from base camp. Base camp to high camp is basically a hike but just above high camp, some rocky steps require moderate scrambling and up through a broad open gully. At the top of the gully, glacier travel begins and proceeds up to a steep snow and ice slope. From here, fixed ropes may be set up by the guides for the strenuous ascent of nearly 100 metres (330 ft) to the summit ridge. The climb to the summit is somewhat difficult due to steep climbing. On top, while Mount Everest is a mere ten kilometres away to the north, the view will be blocked by the massive wall of Lhotse, towering 2,300 m (7,500 ft) above the summit.
A substantial crevasse along most of the headwall leading to the summit ridge has sometimes caused teams to turn back. In April 2009, the Nepal Mountaineering Association tasked the Nepal Mountaineering Instructors' Association with installing stairs (ladders) at the crevasse. As of the 2016 fall climbing season, a 5-meter high fixed aluminum ladder is being used to cross the crevasse.
