Island Peak

Locally known as Imja Tse, Island Peak is a spectacular peak amid the giants of the Himalaya.

This is the approach trek from Dingboche to Chukkung with Island Peak the centre of our attention. We then go around her southern flank, which is to the right of the peak in this photo.

About the expedition

Tucked away up the Chukkung valley this beautiful mountain does indeed look like an island which is dwarfed on both sides by the stupendous Lhotse/Nuptse South Wall to the north and Baruntse to the south. The views from the top of this mountain are truly wonderful, and all the more memorable for a spectacular airy ridge climb to the top.

If you have dreamed of climbing a technical 6000 metre Himalayan summit then this famous mountain may answer your wishes. It was actually a training peak used by Edmund Hillary and Sherpa Tenzing in 1953 and the route they discovered is the same one that is used today. In fact Island Peak is still a popular training peak for clients attempting Mount Everest because a lot of the skills required – crossing crevasses with ladders, using jumars on a fixed line – are the same.

What to expect

The Island Peak expedition Jason Black. The expedition is a minimum 19 days when you include days in Kathmandu and has 16 days on trek / climb. We do recommend allowing extra time for potential flight delays getting into and out of the mountains.

The gradual ascent up the Khumbu valley allows for excellent acclimatisation, which is further enhanced with a climb up Chukhung Ri (5550m) for a great view of the south wall of Lhotse. 

Our main objective, Island Peak, is the final highlight of the trip and a classic 6000m peak which was climbed by Edmund Hillary and Sherpa Tenzing back in 1953 as their training peak for Everest. By the time we come to climb you’ll be well acclimatised and mountain fit.

During the trip, you will learn and use many skills in safe travel on mountains at high altitude including glacier travel, scrambling and moving on mixed snow and ice terrain.  The summit day on Island Peak does involve crossing a crevassed glacier using a climbing rope, negotiating some ladders across crevasses, using a jumar to ascend a fixed line, negotiating a narrow exposed ridge to the summit and then a descending returning to Island peak basecamp.

Climbing Island Peak

The expedition not only provides an enjoyable climb but also provides some of the most spectacular scenery of the Himalayas in the Khumbu region. From the village of Dingboche Island Peak is clearly seen at the top of the valley as a pyramid of ice and rock. It was named by Eric Shipton because of its resemblance to an island in a sea of ice. The mountain itself is the extension of the South Ridge of Lhotse Shar separated by a col and the ridge rising to the south from this point leads to the summit of Island Peak.

The approach route follows the Chukkung Valley to Base Camp, from which the summit is a challenging 9 to 12 hour round trip depending on conditions. The route includes circuitous rocky paths and scrambles to the snow line, followed by a section moving in rope teams across glaciated and crevassed terrain and then a 300 metre headwall to the summit ridge. The headwall is fixed with a rope to clip onto, and this extends all the way along an exposed summit ridge about 300 metres long which is narrow and precipitous but not steep (see photo below). The top itself is quite small with only enough room for maybe four or five people to stand safely.


After climbing the 300 metre headwall and ascending the exposed summit ridge, the view from the top brings the thrill of Himalayan mountaineering because of the spectacular 360-degree panorama of many of the highest mountains in the world. Seen from the summit, the giant peaks of Nuptse (7,879m), Lhotse (8,501m), Lhotse Middle Peak (8,410m) and Lhotse Shar (8,383m) make a semi-circle to the north. The views of Makalu (8475m) in the east, Baruntse and Ama Dablam in the south add to the 360 panorama.

From the village of Chukkung, it is a four hour hike to Island Peak Base Camp on easy ground. The route goes past the famous Imja Tse lake which has recently been drained a bit because of fears that warming due to climate change would cause the lake to break its banks and flood the whole valley.
