Karakoram – Home To K2 (Detailed Overview)

Updated: April 26, 2023

The Karakorams are a large mountain range that span the borders of Pakistan, China and India. It is the second highest mountain range in the world and home to K2, the second tallest mountain in the world.

Below is a guide to the Karakoram Mountain Range, including information on notable mountains and hikes within the range.

The Karakoram Mountains

Width: 200km

Length: 500km

Area: 77,154 squared km
Highest point: K2 at 8,611m.


The mountains in Asia originated from folding in the Cenozoic Era. Granites, gneisses, crystallised schists and phyllites dominate the geological structure. At the end of the Mesozoic Era, the region was characterised by great structural changes.

The Karakoram emerged as a result of intensive geologically recent upheaval. The range is still experiencing frequent seismic activity. Some events are so violent they often trigger massive rock and ice avalanches.


The range runs from east to west. It is characterised by deep narrow valleys, sharp peaks, glaciers and rivers. The average height of the mountain range is 6000m above sea-level. The range is home to four of the world’s 14 peaks exceeding 8,000m above sea-level.

Karakoram is the most heavily glaciated part of the world outside the polar regions with 28-50% of the area covered by glaciers. The Siachen Glacier (76km) and the Biafo Glacier are the world’s second and third largest glaciers outside the polar regions with the Sachen Glacier being the most famous.

There are a total of 7 passes within the mountain range, Khunjerab is the most famous. The Karakoram Highway, a 1,300km long road connecting Pakistan and China is a popular tourist attraction.


The climate of Korakoram is semi-arid and severe. The southern slopes are exposed to the moist monsoon winds coming from the Indian Ocean, while the northern slopes are extremely dry.

The lower and middle slopes receive rain and snow in very small quantities. At elevations of 4,900m and above precipitation is always in solid form. At heights of 5,700m, the average temperature in the warmest month is lower than 0 degrees Celsius and at heights of 3,900m-5,700m the average temperature is lower than 10 degrees Celsius.

Rarefied air, intensive solar radiation, strong winds and great diurnal ranges of temperature are characteristic climatic features of the Karakoram Mountain Range.

Wildlife and Plants

At the lower valleys, all profuse vegetation is anthropogenic. The rocky and arid lower slopes only support discontinuous grazing areas.

Extensive undulating pastures intersperses the high peaks.

The Karakoram have upper and lower treelines, the upper delimited by cold and the lower by aridity. In these lines is only degraded, sparse tree cover. Willow, poplar and oleander thickets occur along water courses up to 3,000m.

Juniper can be found on high slopes among seasonal snowfields.

Shrubs of the genus Artemisia provide sparse cover on the lower slopes.

Hunting as taken a severe toll on the mountain wildlife in the Karakoram. Marco Polo sheep now only breed in the eastern Pamirs and migrate west.

Ladakh urials inhabit the high, flatter mountains to the east and Siberian ibex and markhors negotiate the craggy slopes.

Brown bears, lynx and snow leopards are amongst the endangered species. Wild yak and large raptors can also be found in the mountain range.

Notable Hikes in the Karakorom

Hiking the Karakorams is a life altering experience. But you need to be well-prepared in order to make your journey as easy as possible, make sure you have the right clothing and equipment for the trek you are going to embark upon.

You will most likely be camping on your treks, with a few nights at hotels at the beginning and end of the trek.

A guide is recommended, and there are many tour agencies offering guided treks.

Mountaineering season falls within the summer months of June-September with July and August being the most popular. You will definitely want to avoid the harsh weather and heavy snows of the winter months which would make your trek more dangerous.

Below is a list of notable hikes/treks in the Karakorams.

K2 Base Camp Trek

The trek to the K2 Base Camp is considered to be one of the world’s greatest treks with its breathtaking scenery and view of some of the world’s highest peaks. The trek should take between 9-15 days and you can expect to be trekking for around 5-7 hours a day.

You will trek up the mighty Baltoro Glacier and take in the incredible views of the great peaks of the Karakorams.

Although this isn’t the K2 summit, the trek is still very challenging, and you should be prepared and physically fit.

Experience one of the most spectacular treks in the world with the K2 Base Camp Trek.

Snow Lake and Hispar La Trek

The Snow Lake is a high-altitude basin which is over 16km wide and is located at the head of the Biafo and Hispar Glaciers. The trek crosses the two glaciers end-to-end, this is the longest glacial system within the Karakorams at 116km long.

Where the glaciers meet lies the Snow Lake, which is encircled by unnamed and unexplored peaks.

You will have the privilege of trekking in a truly remote and stunning area. The trek is considered by some to be one of the most beautiful treks in the world. You will trek past stark mountains, icy white glaciers and gorgeous flower-filled meadows.

Although beautiful, the 15-day trek is strenuous, and you will need to be physically fit in order to complete the journey.

Your accommodation will be a combination of camping and hostels.
