Island Peak Difficulty: Know Factors Determining Difficulty Level

Island Peak which is also known as ‘Imja Tse’ is at an elevation of 6,189 meters (20,305 feet) and is one of the most mystical and popular climbing peaks in the northeastern part of the Himalayas. Used for training by Edmund Hillary and Tenzing Noragay Sherpa during their 1953 Everest expedition, since then it has become a popular practice peak for climbers who are on their journey to scale the tallest mountain in the world, Mt. Everest (8,849 meters) or expedition of the other highest peaks in the world.

As this magnificent mountain in the Imja Khola Valley is considered a practice peak for beginner mountaineers, you might be wondering how difficult this expedition will be. Although it is considered a training peak for beginners, Island Peak difficulty is at a ‘Moderately Difficult’ level.

Climbers need to have mountaineering skills and should be proficient at using various tools for Island Peak climbing. This iconic expedition is best suited for novice climbers who want to experience the technical slopes of the mountain which are slightly more advanced than the regular trekking peaks to prepare efficiently for the scaling of the highest peaks in the world.

Island Peak Difficulty- Technical Segments

The Island Peak difficulty has been graded at the ‘2B’ level in the Alpine Grading System. Even though it is among the practice peaks recommended for beginners, it is still not a trekking peak that can be scaled without using mountaineering tools.

Climbers are required to have an adequate level of understanding of mountaineering techniques and should be adept at using various tools like ice axes, crampons, harnesses, climbing ropes, snow bars, ice screws, etc. Despite being listed among the other practice peaks in the Himalayas, Island Peak difficulty comes pretty close to the expeditions of the 8,000-meter class mountain.

On this beautiful Himalayan peak, the climbers will be able to understand the true essence of a mountain expedition. Not only the climbers will come face-to-face with the alpine environment with slipper ice and snow segments but will also get the opportunity to practice mountaineering skills to overcome the technical segment on the mountain.

Although it is one of the most challenging expeditions among the practice peak, novice climbers with adequate skills will be able to easily handle the challenges thrown their way. Even though the technical segments on the mountain offer a similar level of challenges to the high mountain expedition, it is still at the 6,000-meter class. Thus, the novice climbers will have a better understanding of the difficulty they will be facing on a larger scale during the 8,000-meter class expeditions.

The summit day of the mountain is considered one of the most challenging parts of the overall Island Peak difficulty. Climbers have to overcome approximately 9-10 hours of summit push during this day and overcome vertical ice walls. The expeditioners also have to use anchors on the fixed rope to move from one point to another making it the most technically demanding day of the entire expedition.

    Overall Difficulty Level Breakdown

    Although the Island Peak difficulty is at a moderately difficult level, it is difficult to precisely assess the overall difficulty level. For instance, some might find it harder to acclimatize at the rising altitude, meanwhile, others might have difficulty with the trekker period and the cold alpine environment.

    So, the significant part of the difficulty factors depends on the natural abilities of the climbers as well as the efforts they put into their training and preparation. Let’s break down some of the major Island Peak difficulty factors that you have to deal with during your expedition.

    Altitude Gain

    As this is an alpine adventure to scale the summit of the 6,000-meter class mountain in the Himalayas, altitude sickness is one of the major difficulty factors of this adventure. As there are risks for the human body to catch altitude sickness above the altitude of 2,500 meters, you have to be careful during high-altitude trekking adventures.

    However, Island Peak Climbing is an actual scaling adventure, so the climbers have to spend a significant amount of time in the alpine environment where acclimatizing is more difficult than on land. Thus, climbers are more vulnerable to different types of altitude sickness like Acute Mountain Sickness (AMS), and more severe forms of altitude sickness like High Altitude Cerebral Edema (HACE) and High Altitude Pulmonary Edema (HAPE).

    Starting your adventure at Lukla (2,860 meters), you will overcome the high altitude jump points like Namche (3,445 meters), Tyangboche (3,975 meters), Dingboche (4,360 meters) and summit of Island Peak (6,189 meters). So, the elevation gain in this mountain expedition can be a challenging factor if you are not well prepared to counter it.

    Route Difficulty

    After altitude gain, another contributing factor to the Island Peak difficulty is the route of this expedition. Starting from the remote rugged route of the Himalayas you will venture on the ice and snow segments on the mountain slope. During the trekking adventure, you will trek approximately 10 km to 14 km during each day of your trek, so you will be walking for about 5- 6 hours every day on average.

    It may not seem like a big deal considering the distance and trekking hours, but traversing across remote rugged landscapes in rising altitudes isn’t an easy feat. Furthermore, once you start scaling the snow and ice segment of the mountain, overcoming the route difficulty is even more challenging. During the summit day, the most demanding part of the entire expedition, you will continuously have scale for 8- 9 hours on snow and ice segments of the mountain, of course overcoming the technical part using different mountaineering tools.

    Climatic Conditions

    Although the peak seasons are the most favorable period for any kind of high-altitude adventure in Nepal, the climatic conditions of the high Himalayas can be unpredictable at times. It doesn’t take much time for the situation to turn worse from bad, so as a climber, you will have to be prepared for whatever the mountain throws your way.

    High winds, blizzards, avalanches, and wide crevasses are some of the outcomes of the unpredictable climatic conditions in the Himlayan region. Furthermore, the change in climate has also seen an increase in the number of natural calamities during mountain expeditions in recent years. If you decide to do this expedition during the off-seasons like winter or monsoon, the bad climatic conditions can elevate your overall Island Peak difficulty.


    Island Peak Climbing is a Himlayan expedition that takes place in a remote and secluded part of the country. Despite being one of the most amazing prospects of Himlayan climbing, the remoteness part of this expedition is inevitable. As a climber, you have to overcome the remoteness factor from your trekking route to scaling the icy slope of this beautiful mountain.

    Due to the lack of proper transportation modes in the Himalayan region, this region hasn’t seen much development. The teahouses along the trail offer moderate levels of food and accommodation facilities, however, the medical facilities in the area are limited. Thus, in case of any medical emergency, helicopter rescue is the only viable option in the region.

    The same goes for other services and amenities, electricity, internet, and other telecommunication mediums are limited to the lower region, and the higher regions are dependent on solar power. So, it would be folly to expect luxurious services and amenities during this expedition, and if comfort and luxury are your best friends, adjusting to the available services and amenities can be your major Island Peak difficulty factor.


    If you have previous mountain expedition experience or have done any kind of high-altitude adventure, then you understand the significance of the acclimatization days in your adventure. It is recommended that you should not climb over the altitude of 500 meters in a single day’s adventure and you should have at least one acclimatization day after gaining more than 1,000 meters in altitude.

    These recommendations are essential in any kind of high-altitude adventure as they help your body to properly adapt to the rising altitude. However, when it comes to alpine environment acclimatizing is much more complicated, so you will need enough time to properly settle in at the altitude without putting your life at risk.

    You can take it as ‘the more acclimatization days you get, the more comfortable your experience and overall higher success rate of your expedition’. The lower number of acclimatization days in your expedition puts more strain on your body and scaling the mountain without proper rest also puts you in danger of altitude sickness and other non-AMS-related illnesses.
