If you are looking for a thrilling endeavor, Island Peak Climbing is one of the best choices. It is a spectacular journey into the mysterious Himalayas that will quench your thirst for challenging adventure. 

The locals call the peak "Imja Tse" in the Sherpa language, which also translates to Island Peak. The peak sits at the top of Chukung Glaciers and looks like a lone island amidst the sea of snow and ice. Hence, Sir Eric Shipton named the peak during his 1951 Everest expedition. The peak lies near the point where Imja and Lhotse Glaciers intersect. 

Negotiating crevasses in snowfield along the route to the summit of Imja Tse.

The route to Island Peak follows the classic Everest Base Camp route. Lukla serves as the gateway for the trek and passes by several famous Sherpa settlements like Namche Bazaar, Tengboche, Dingboche, Gorakshep, Chukung, and more. En route, you will also pass by several ancient monasteries, the most renowned being the Tengboche Monastery.  

Island Peak Climbing has been a favorite trekking peak among mountaineers as a practice climb for Mount Everest. In addition to the challenges, the summit offers mesmerizing panoramic views of the world's highest mountains like Mt. Everest, Mt. Lhotse, Nuptse, Ama Dablam, Lobuche Peak, Thamserku, and more.  

Island Peak Climbing has a 2 B-level Alpine Grading System. This means that the route has some technical sections, and climbers must have basic knowledge of mountaineering tools. With proper preparation, even beginners can participate in the expedition to the Island Peak. The trek combines the Everest Base Camp Trek with the Island Peak. Hence, this trek in Nepal attracts numerous trekkers and mountaineers every year.

Best time for Island Peak Summit

The best periods for Island Peak Climbing in Nepal are spring and autumn. These seasons have stable weather, clear skies, and warm temperatures. Hence, they are also peak trekking seasons. Here is a brief explanation of these two times:  

Spring (March to May)

As the spring season begins, the temperature slowly rises, and the days become longer. The weather is pleasant, and the sky is clear. Therefore, you can witness the scenery and mountain vistas without any obstructions. It is also when the flora and fauna are the most active. Walking along the forest trails, you will see the forests of rhododendrons and Himalayan wildflowers in full bloom. 

The temperature above 4000 meters is still cold, especially at nighttime. The average daytime temperature ranges from 10 to 17 degrees Celsius. Meanwhile, the nighttime temperature can drop below 0 degrees Celsius. There are minimum chances for rainfall. Similarly, the temperature will gradually become warmer as spring progresses. 

Autumn (September to November)

Autumn is the next best season for Island Peak Climbing because of its stable weather conditions. The vegetation looks lusciously green and vibrant. Likewise, the colorful foliage adds to the scenic landscapes. The lower altitude region can receive little rain during early autumn, but precipitation decreases as the season progresses. Visibility is crystal clear at this time. 

The average daytime temperature ranges between 7 and 15 degrees Celsius, and the nighttime temperature is around 5 degrees Celsius. The weather becomes chilly by the end of autumn as pre-winter enters Nepal. You can also enjoy the festive atmosphere while trekking, as two of the biggest Nepalese festivals, Dashain and Tihar, fall in autumn. 

Note: The weather at higher elevations can change at any time. Therefore, please check the weather forecast before planning the Island Peak Climb. You should also consult a local agency or an experienced guide for the most current weather reports.


Acclimatization in Island Peak Climbing Expedition 

Acclimatization is crucial for high-altitude treks and climbs like the Island Peak Climbing. Therefore, Core Treks has crafted an ideal Island Peak itinerary that allows you to acclimate properly before ascending to higher elevations. Likewise, we will gradually climb to high altitudes to minimize the risk of altitude sickness. 

Our itinerary includes acclimatization days at Namche Bazaar (3,440 meters) and Dingboche (4,400 meters). During the acclimatization day, we must stay active, which helps our bodies better adapt to the higher altitudes. 

Namche Bazaar is Sherpa's capital and a trading hub of the Everest region. While on our acclimatization day at Namche Bazaar, we will take a short hike to Syangboche (3,720 meters), which is slightly higher. It helps to train our bodies to adapt gradually. We can witness the gorgeous scenery of the surrounding mountains and landscapes. Then, we will hike to one of the world's highest hotels, Hotel Everest View (3,962 meters). After a whole day's elevation, we will return to Namche. 

Dingboche is another Sherpa village where we will spend an acclimatization day. We will take a short excursion to the Nangkartshang Peak (5,083 meters) on this day. The hike to the peak takes around 3 hours, and you can see splendid mountain vistas from the top. We will then return to Dingboche and explore for a while. 

Despite acclimatization, you can experience symptoms of altitude sickness. Thus, you should listen to your body, and if you feel any discomfort, you should immediately ask your guide. If you start experiencing severe symptoms, you should immediately descend to the lower altitudes.


A typical day on trek and climb on Island Peak

Our typical day during the Island Peak trek/ climb begins early morning. We will continue our trek around 7 to 8 AM after breakfast, depending on the destination. We will trek for 3 to 5 hours before taking a short lunch break. Most often, we will have lunch around midday.

After reaching our destination, we usually have dinner around 6 to 7 PM. After dinner, your trek guide will brief you on the next day's trek. Then, you are free to spend the evening as you please. 

Each day will be an exciting journey. You will witness beautiful scenery, explore new places, and have numerous opportunities to take photographs. However, sometimes, weather and route conditions can create obstacles. But do not worry. With our expert guides, you are in safe hands.

Namche Bazaar to Tengboche

As we begin our trek towards Tengboche, the trail becomes narrow and runs along the banks of the Dudh Koshi River. We can also witness the magnificent Himalayan range at a distance. The trail is even level without any steep ascents or descents. Thus, we can focus on enjoying the nature around us rather than the rough terrain. We will reach a small settlement, Phunki Thenga, from where we must climb steeply to Tengboche. 

The Tengboche village is home to Everest region's biggest monastery, the Tengboche Monastery. We will tour the monastery and begin with the main hall. There is a splendid 20-foot Buddha statue in the main hall. Numerous fine textile pieces at the monastery reflect this region's rich cultural traditions. Similarly, we can hear the musical instruments and chanting by the Lamas. The monks perform daily prayers at this sacred site, which plays a role in spiritual manifestation. It also links us to the very heart and soul of the Everest region.

During the trek, we can watch the sunrise up close in the morning or the sunset outside in the evening, depending on our schedule. Tengboche is where nature's canvas and religion's canvas form an extraordinary masterpiece. You can marvel at the Himalayas' natural splendor in the monastery's calm atmosphere.

Preparing for a trek in Nepal requires careful consideration of the route and the prevailing weather conditions. To help you pack wisely, we have compiled a comprehensive Peak Climbing Packing List.


The Island Peak expedition intimidates even seasoned climbers. It is a challenging climb that requires a few technical skills. However, the challenge is worth every moment. The summit treats you to magnificent Himalayan views in the Khumbu region. Additionally, the thrilling adventure is unlike anything you have experienced. 

From the Dingboche village, the peak looks like it sits amidst a sea of ice and snow, so Sir Eric Shipton named it Island Peak. The mountains form the southern ridge of Lhotse Shar, and the regional col joins them to create the ridge that leads to the summit of Island Peak.

En route, trekkers must ascend trails from the gorgeous Chukkung Valley and Island Peak Base Camp to reach the peak summit. Depending on the weather, reaching the summit can take 9 to 12 hours. The trails are rugged and steep, with sections of rock scrambling. As you go higher, you must cross the glacier and get to the spine of the ridge. The ridge sits over the crevasse-filled traversing terrain, which is 300 meters tall. 

Our guides and support team will fix ropes on the headwall to support climbers. These serve as the climber's lifeline, extending to about 300 m. When you reach the top, you will have scaled the 300-meter headwall and the summit ridge. Although the ridge is not steep, it is still narrow. 

The summit of Island Peak itself is quite small. It can only hold a small group of climbers at a single time. Similarly, the cold air of high altitude sets in the body and gives you the thrill of Himalayan mountaineering. The scenery from the summit is also exquisite. It offers a 360-degree vision of some of the highest peaks in the world. 

You can witness the massive Nuptse (7,879m), Lhotse (8,501m), Lhotse Middle Peak (8,410m), and Lhotse Shar (8,383m) form a semicircle to the north. Likewise, the magnificent views of the peaks Kangchenjunga, Chokrin (8,585m) to the north, Makalu (8,475m) to the east, and Baruntse and Ama Dablam to the south complete the entire mountain scenery.


The Island Peak Expedition requires you to trek on diverse terrains. For this, you will require cautious navigation and technical skills. Therefore, hiring an experienced guide will help you navigate the terrain and ensure your safety. The start of the journey is similar to the Everest Base Camp trek. You will have to make steep ascension on rough and irregular terrains. However, the ultimate tests come when you begin your climb from Island Peak Base Camp.

You will encounter steep scrambling sections on loose rocks beyond the horizon. These sections end when you reach the snow line, called the "crampon point." Climbers must navigate a circuitous path through rock formations. The view gradually changes into snow-covered plains. Then, rope parties of three to four will have to walk through multiple crevasses. You have to pay extra attention to avoid critical slots or crevasses.

At the base of the headwall, you will reach the fixed lines. You must inspect the latter carefully before you continue. Anchors are usually safe, and guides place them at the proper spacing. Then, you will reach the climbing part. You will have to climb mostly 40-degree slopes. Also, it is crucial to take frequent stopovers to check equipment while climbing. It is worth mentioning that having other climbing teams around can slow you down. Coordination and clear communication are a must during the climb.

As you reach the final part, the path narrows and exposes the climbers to a dangerous drop. Communication between fellow climbers is vital, particularly during climbing steeper and more exposed routes. You will use the simple one cable, which steadies to the peak. Only a few climbers can use the cable at a single time. You will then clip the safety karabiner on the anchor and proceed to the jumar. Likewise, you must clip the second karabiner at the point to keep you secured to the rope.

The descent is even more dangerous than climbing. You must be cautious when descending on a vertical surface from the summit ridge. For experienced climbers, using the supports on the platforms to help them proceed is a piece of cake. On the other hand, those with less experience may need more time. 

When you return to trekking on the glacier, you must modify light conditions. It requires extreme caution, as the positions of ladders may shift when the snow gets squished. You must keep the ropes tight and follow proper climbing rules to rappel down safely. By following the correct instructions and techniques, you can make a safe return to the base camp.


During the Island Peak Trek, you will find many teahouses, lodges, and guesthouses along the route. Locals run these accommodations and offer only basic services. Every lodge usually has a communal area with a stove. They provide bedrooms with two beds, mattresses, pillows, and blankets. Similarly, most of these places have shared squat-style bathrooms. You can also find rooms with attached bathrooms in lower altitude regions. 

The rooms are mostly unfurnished and may not be well insulated. Therefore, it is best to carry sleeping bags to keep you warm at night. Most lodges have gas heaters in the showers. You must pay extra for hot showers/ water, charging electronic devices, laundry, and internet. 

Another accommodation option is tent camps. However, accommodation options are abundant, so most trekkers stay at lodges. You will stay at tented camps at the Island Peak Base Camp. Core Treks will provide a two-person tent with trekking poles for easy set-up and takedown. Since the temperature is significantly lower at the base camp, you will need a 4-season sleeping bag.  

You can enjoy delicious food during the trek, including local Nepali/Sherpa cuisine and Western recipes. You can enjoy diverse food options, including burgers, chips, and dal bhat, a staple Nepali dish. The menu can include options such as momo, noodles, pasta, sandwiches, soups, stews, breads, porridge, curries, and more. Note that the food options can get limited as you go to a higher altitude.


Before embarking on the Island Peak expedition, you must learn a few climbing skills. Although the trek does not require extensive skills, you must learn some basics. For example, you must be able to tie into a harness and onto a man rope, which is also essential for anchoring. You must walk on varied terrains, glacial ground, cross crevasses, and climb ridges. 

Although the Island Peak Climbing is ideal for beginners, prior experience is beneficial. Similarly, you must hire a licensed, experienced guide to navigate Island Peak's terrains and provide logistical support. They will guide and deliver correct instructions during the climb. Likewise, they will help you avoid hazardous paths to ensure your safety. 

There is a rope ascending device ( jumar, also known as 'cow's tail') along the headwall of the Island Peak and a descender for abseiling back down. Similarly, you must correctly use ropes, crampons, or an axe. Therefore, we recommend that you receive training and practice beforehand. You want to avoid being in the position to use any of these equipment and gear for the first time right before the climb. 

En route to the summit, you will encounter several narrow crevasses requiring ladders to cross. Some can find crossing the ladder difficult. So, the best way to cross the ladder is to climb across the rungs with the metal tips of the crampons facing down the ladders. Some climbers may find crawling more effective.

The headwall of Island Peak has wide ledges but is relatively steep. Many climbers prefer to go up by "jugging" along the ropes via their jumars. They use it to pull themselves up as the ropes act as suspension. But multiple people using a single rope simultaneously can be dangerous. You should only trust an anchor if you have personally set it up or seen the position with your own eyes. We recommend using your crampons and axe to climb with rope protection instead of trusting it all on the rope.

The summit of Island Peak is exposed, with steep drops on either side. Thus, concentration and mental toughness are crucial for climbing Island Peak. People with vertigo or acrophobia may find climbing difficult. In addition to the skills, a positive mindset and mental resilience are essential for the climb.


Island Peak Climbing is not the easiest peak climb and is more challenging than the Mera Peak Climbing. However, it is still relatively easier than other peak climbs in the Everest Region. It requires technical skills to climb to the summit. Let us look at the different levels of difficulty in climbing Island Peak.

Suitable for Advanced Beginners

A few mountain destinations in the world significantly resemble tropical islands. Island Peak is among them and is ideal for advanced beginners. Its need for technical skills and climbing experience may only be suitable for some beginners. The tech part of the climb can be tricky if you have no prior knowledge and experience. Any climbers with intermediate-level climbing gear skills can take part in the climb. 

Altitude Sickness

Climbing Island Peak, at 6189 meters, has the risk of altitude sickness. Trekkers can succumb to the sickness due to the depleting oxygen level in the atmosphere. Acclimatization is crucial to minimize the risk. It allows your body to adjust to the changing elevations and surroundings. Core Treks' Island Peak Climbing itinerary includes two acclimatization days at Namche Bazaar (3720 meters) and Dingboche (4400 meters).    

Weather Conditions

The weather at higher altitudes is unpredictable and can be a real surprise. It is one of the factors contributing to the expedition's difficulty. While climbing the peak, we strongly advise you to begin as early as possible. You should avoid noontime when strong winds could make the climb further challenging.

Technical Aspects

Although Island Peak does not require extreme technical skills, you will need a few. There are sections where climbers must demonstrate some mountaineering skills. Experienced or intermediate climbers with a basic knowledge of the climbing gear can successfully overcome those sections. The guidance of professional guides is also crucial. These technical sections may be challenging for beginners without prior experience.

Trekking Routes

The Island Peak trek route shares the same course as the famous Everest Base Camp Trek. The daily average trek time can vary from 7 to 8 hours or  9 to 10 hours, depending on the destination. The trail deviates from the Everest Base Camp Trekking route from Chukhung. From here onwards, the trails and terrains become more difficult and steeper with uphill climbs.

In short, Island Peak climbing is a relatively easy venture but involves some challenges. Trekkers have basic rock climbing experience, technical skills, and gear competence. When evaluating the difficulty of the Island Peak, you must consider its routes, terrains, weather conditions, and technical details. You must also assess your health and fitness level before joining the expedition.

Beautiful mountains and delicious food

From: Australia | On: 28 Sep, 2018

Have been planning the Everest summit for the last few years. I finally had time to fly out to Nepal and trek to the world’s tallest mountain, the Everest. It is surprising that Nepal has way more to offer than just the landscapes.

The cuisine of Nepal is really delicious. You might find it spicier but that’s the way to go for me. Talking about the trekking itself.

It was fairly challenging but CoreTreks and the guiding team helped me through it. That is why recommend CoreTreks if you are looking for future trip to the mountains.

An amazing experience with Nepal and Nepalese

From: United Kingdom | On: 16 Apr, 2018

Challenging trek but worth it

From: United States | On: 12 Apr, 2017

It was one hell of a trekking and climbing. We completed the trek with Atma Ram Bhatta and Narendra Bhatta who were both helpful and hardworking individuals from CoreTreks.

Nepalese people are very kind and that filled my heart with joy as we continued to hike up through local Sherpa Settlements.


I would suggest the team to consider more comfortable transportation means as some of them were somewhat uncomfortable. Besides that, love the trip, love Nepal, will definitely visit again.
