island-peak-climbing Overview

Island Peak is a mountain that lies in the eastern part of Nepal, on the border of Nepal and Tibet. It lies at the head of Imja Khola valley and therefore it has the name Imja Tse. The area is highly protected by Sagarmatha National Park which includes diverse flora and fauna. In 1953, the British Mount Everest expedition named this peak an Island peak. This was due to the fact that the peak actually appears as an Island in a sea of ice when viewed from Dingboche.

The Island peak is the continuation of the South Ridge of Lhotse Shar separated by a col. The southwest of this peak was first climbed by Tenzing Norgay, Charles Evans, Alfred Gregory, Charles Wylie, and 7 other sherpa in 1953. It was done before just as a part of a training exercise by a British expedition that went on to Summit Mount Everest. Hans-Rudolf Von Gunten with two other Sherpas as members of the Swiss team however remains first to climb the summit that went on to make the second ascent to Mount Everest and first ascent of Lhotse.

The climb to the Island peak is technically challenging and risky, especially from the base camp. The low base camp of Island peak lies at an altitude of 5087m, and the high camp at 5600m. It is more likely to suffer mountain sickness from the base camp. The trail to the summit is heavily covered with steep snow, frozen glaciers, and ice slopes. It is very important to have strong physical and mental fitness along with the skills to use mountaineering gear.

This route takes around 20-22 days with proper rest and days off. It cost you around 900-1100$ including all your flight tickets, travel insurance, permits, food, accommodations, etc.

Safety and fitness

The first important thing to understand is that Island peak is not categorized as a trekking peak. Not anyone with basic ideas can just go and start climbing. It is mandatory to have high mountaineering skills, experience, focus, and patience. Second Important thing is to choose a perfect itinerary that gives proper acclimatization to the low level of oxygen. Or else, you are going to have a huge problem of altitude sickness. And finally, great fitness, mental stability, and strength are very important. The average walking hour is 6-7 per day and the use of crampons, ice harness, ice ropes, etc are required during the climb. The way to the summit is very difficult and the summit ridge is quite airy with steep drops off to the sides. The highest altitude here is 6189m, hence, there is always a risk of mountain sickness.

Food and Accommodation
There are enough teahouses from Lukla which provide basic facilities like a warm room, blankets, and pillows. But they have to be shared with other trekkers as well. Also, the washroom and toilets have to be shared. They also provide home-cooked meals like Dal, Bhat, vegetables, noodles, pasta, soup, etc. However, once you arrive at the base camp, no teahouses are available and the only solution is to camp. You have to prepare food by yourself. All the equipment like tents, sleeping bags, mats, cooking gas, utensils are very much important in this trek. If you choose to travel through the agencies they will hire a cook for you and also manage the camping for nights.
Electronics and communication
When you are in the teahouses, all kinds of facilities like electricity, internet, mobile coverage, are available. There will be no problem with charging your electronics or talking to your family. Once you arrive at the base camp, all these facilities are not available. You will be camping those days and only satellite phones are used for communication. Extra batteries and power banks are highly recommended.
Permits and fees
1) Sagarmatha National Park Entry Permit · NON-SAARC countries- 3000 (excluding VAT) · SAARC countries- 1500 (excluding VAT) 2) Pasang Lhamu VDC permit – 2000 NRS 3) Island peak climbing permit - Spring (March-May)-250$ - Autumn (September- November)-125$ - Winter (December- February)-70$ - Summer (June-August)-70$
Guides and porters
When it comes to peak climbing, professional, licensed, well-educated, and experienced guides are everything you need. They lead you, they have great knowledge about directions, people, villages, camping sites, etc. Since you will be carrying all the stuff for camping you will definitely need a porter to help you. Guides usually charge up to 35-40$ per day and porters charge around 25-30$ per day. However, if you choose to travel through agencies they will hire a guide and a porter for you.
The gateway for Island peak is Lukla and the easiest and fastest way to reach Lukla is to take a flight from Kathmandu which only takes 35 minutes. You can also travel by bus but it is certainly a tiring route. There is no direct connection between Kathmandu and Lukla and you need to travel via Jiri.
