Island Peak, also known as Imja Tse, is a popular and adventurous climbing peak in Nepal. In fact, it is one of the most sought-after peaks by both experienced and beginner climbers. Island peak stands tall at the height of 6160m. From a distance, the peak seems as if it is surrounded by a complete of sea of ice and hence its name.  
 
Island peak climbing is both a challenge and a rewarding experience as the summit of Island Peak offers stunning views of beautiful Everest, Lhotse, Nuptse, Ama Dablam, Makalu and many other astounding peaks. Expedition teams often use Island peak as a peak for acclimatization and warm-up before attempting to climb Mt. Everest and Mt. Lhotse. Island peak is actually an extension of southeast ridge of Mt. Lhotse.
 
The first part of the Imja tse climbing journey involves trekking through the Khumbu region via Sagarmatha National Park. You will be popping in famous places such as Lukla, Phakding, Namche, Tengboche Monastery, Dingboche among others and taking in the beauty of spectacular mountains and rich biodiversity spread in front of your eyes. During acclimatization in Namche, cherish the opportunity to experience Sherpa hospitality and beautiful mountains.


Island peak Base Camp & climbing arrangements

The base camp of Island peak (Imja tse) is located at an altitude of 5,087m. To reach the summit of Island peak involves walking through gully, crevasses, snow and glaciers. Our climbing guide will help you to fix ropes and teach you essential climbing skills for glacier walking which will be very important especially during the last 100m of ascent.
 
Once the climbing is done, you will be retracing the same steps backwards to Lukla. This time you can loosen up a bit and take more time to take in the surrounding beauty of Khumbu region. Those with more time on hands can climb down from Island Peak and hike up to Kala Patthar and Everest Base Camp before returning to Lukla. Kala Patthar situated at an altitude of 5644m and provides an unparalleled panorama and close up views of Everest, Lhotse, Khumbu Glacier among others. You can also fulfill the dream of reaching Everest Base Camp (5364m) by hiking further from Gorakshep.
 

Who can climb Island Peak?

Island Peak climbing is a perfect trip for those who are looking for a trip which is more challenging than trekking. It would be the best choice for climbing beginners to gain some essential climbing skills and knowledge. It can also be climbed in order to get enough acclimatization before making final summit of 8000 meters mountains including Everest and Lhotse.
 

Best season for Island Peak climbing:

Normally, September, October, and November in autumn season and March, April and May in spring seasons are considered as the best months for Island Peak climbing. Usually, the weather and temperature during these months remain favorable for climbing. However, we can also arrange this expedition throughout the year.

 
Nepal Environmental Treks & Expedition has been organizing climbing expedition on Island Peak (Imja Tse peak) successfully over the years. Our experienced high altitude climbing crews (guides, porters and cook) are there to assist you to turn your dream of reaching the top of Island Peak into reality.

Island Peak Climbing (Imja Tse) Altitude Profile

FAQs

Island Peak, also known as Imja Tse (6,189 meters / 20,305 feet), is one of the most popular trekking peaks in Nepal, located in the Everest region. It was named “Island Peak” by Eric Shipton in 1951 because it appears as an island in a sea of ice when viewed from Dingboche.

  • It gained popularity because:
  • It’s considered an excellent introduction to Himalayan mountaineering.
  • It combines trekking and basic alpine climbing.
  • It offers spectacular views of Lhotse, Ama Dablam, and Makalu.
  • It serves as a training peak for climbers aiming for higher mountains like Everest or Lhotse.
  • Despite being categorized as a trekking peak, Island Peak requires good fitness and basic mountaineering skills.

Island Peak is considered a moderately technical climb. While it's achievable for fit beginners with proper preparation, prior experience with basic mountaineering techniques (like using crampons, ice axe, and fixed ropes) is highly beneficial.

Key challenges include:

A steep ice headwall near the summit (about 100 meters of fixed rope).

Crevasses on the glacier (may require ladder crossings).

High altitude – risk of Acute Mountain Sickness (AMS).

Cold temperatures and wind.

If you're new to mountaineering, a short climbing clinic before the summit push is typically provided by guiding companies. Being in excellent physical condition is essential.

The best seasons to climb Island Peak are spring (March to May) and autumn (September to November).

a. Spring (Mar-May):

Stable weather, blooming rhododendrons, and good visibility.

Warmer temperatures compared to autumn.

May attract more climbers, especially in April.

b. Autumn (Sep-Nov):

Clear skies and crisp mountain views.

Cooler and drier conditions—ideal for climbing.

Fewer chances of rain and avalanches.

Climbing in winter is possible but requires strong preparation for cold and snow. Monsoon (June-August) is generally avoided due to rain, slippery trails, and poor visibility.

A typical Island Peak expedition takes 16 to 20 days, depending on acclimatization and whether it includes the Everest Base Camp (EBC) trek.

Some itineraries combine Island Peak with Everest Base Camp or Kala Patthar for added adventure and altitude adaptation.
 

You’ll need several permits:

Island Peak Climbing Permit – Issued by the Nepal Mountaineering Association (NMA)

Sagarmatha National Park Entry Permit – Required for entering the Everest region

Khumbu Pasang Lhamu Rural Municipality Permit

These are usually arranged by trekking agencies, but it’s good to verify this before you go.

Island Peak demands a high level of cardiovascular endurance, leg strength, and mental stamina. A well-rounded training program should begin 2–3 months in advance and include:

Hiking and hill training with a weighted backpack

Running, cycling, or swimming for cardio endurance

Strength training (especially legs and core)

Stair climbing and endurance hikes (5–8 hours)

Altitude simulation if possible (like hypoxic training)

Practice with crampons and ice axe, if available

Mental preparation is just as important as physical – summit day is long (10–14 hours), cold, and demanding.

While Island Peak is considered a non-technical trekking peak, several risks exist:

Altitude sickness (AMS, HAPE, HACE)

Falls or slips on the glacier or headwall

Crevasse danger on the glacier route

Weather changes – snowstorms, high winds

Frostbite or hypothermia

These risks are minimized with proper acclimatization, experienced guides, weather monitoring, and proper gear. Always have travel insurance that covers high-altitude evacuation.

Yes, while not legally mandatory, hiring a certified guide is highly recommended for safety and logistics. A guide helps with:

Route finding, rope fixing, and glacier navigation

Emergency decision-making

Coordinating logistics, meals, and permits

Providing climbing instruction for first-timers

Many outfitters offer full-service guided climbs, including gear, porters, accommodations, and meals. Solo attempts are risky and not encouraged unless you’re highly experienced.

The cost varies based on services, itinerary, and season, but here’s a general range:

Full package from Kathmandu: $21,00 – $3,500

The cost typically includes:

Domestic flights (Kathmandu–Lukla)

Guide and porter services

Permits and logistics

Accommodation (teahouses + tent at base camp)

Meals on the trek and climb

Some climbers prefer to join group departures for reduced costs.
