K2: The Savage Mountain

Oscar Eckenstein and Aleister Crowley led the first attempt, reaching approximately 6,600m on the Northeast Ridge.

Achille Compagnoni and Lino Lacedelli of Italy reached the summit on July 31 via the Abruzzi Spur, completing the first ascent.

A large Japanese expedition made the second ascent via the Abruzzi Spur, 23 years after the first, a mark of K2's extreme difficulty.

13 climbers summited across multiple expeditions, but 13 also died. Wanda Rutkiewicz became the first woman to summit K2.

Spanish climber Carlos Soria summited at age 65, while multiple international teams reached the top in favorable conditions.

A Nepali team of 10 climbers led by Nirmal Purja and Mingma Gyalje Sherpa reached the summit on January 16, completing the last 8000m winter ascent.

K2 is 8,611 metres high, the second-highest mountain on Earth after Everest and the highest point in Pakistan. It stands in the Central Karakoram of Gilgit-Baltistan, straddling the border with China's Xinjiang, at the junction of the Baltoro and Godwin-Austen glaciers. The great majority of expeditions climb from the Pakistani side, reached from Skardu. There is no road and no village near the mountain. The last jeep track ends at Askole, and from there the approach follows the Braldu River and the Baltoro Glacier for about seven days, past the Trango Towers and Masherbrum, to Concordia, where four 8,000-metre peaks stand in view at once. From Concordia it is a final day up to Base Camp on the Godwin-Austen Glacier at about 5,000 metres. Broad Peak and Gasherbrum I and II are all within sight of K2, and there is no helicopter rescue at altitude.

Yes. The K2 Base Camp trek takes you to the foot of the mountain with no climbing at all, and we arrange it separately from our expeditions. From the jeep track at Askole the trail follows the Braldu River and then the Baltoro Glacier for about seven days. You walk beneath the Trango Towers, some of the largest granite walls in the world, and the fluted ice of Masherbrum before reaching Concordia, where the Baltoro meets the Godwin-Austen and four 8,000-metre peaks stand in view at once. From Concordia it is a final day up to K2 Base Camp at around 5,000 metres on the Godwin-Austen Glacier. The whole trek takes roughly two weeks. It is one of the great treks on Earth, and many people do it as a goal in itself rather than as the start of an expedition. You still need to be fit and ready for glacier walking at altitude, but no mountaineering skill.

K2 is the hardest of the fourteen 8,000-metre peaks to climb. Its summit success rate sits around 25 to 30 percent, against 50 to 65 percent on Everest. The difficulty is structural: the mountain is steeper, more technical and more exposed, with no easy line from any side. On the standard Abruzzi Spur you climb rock buttresses and chimneys to Camp 2 at 6,700m, then the Black Pyramid, a steep mixed rock-and-ice band, and finally the Bottleneck at about 8,200m, a narrow ice couloir under hanging seracs. K2 is not a first 8,000er. Operators expect a previous 8,000-metre summit or at least strong experience on 7,000-metre peaks, with confident use of crampons, fixed ropes and ascenders on steep ground. The weather turns fast and self-reliance is the rule. Patience and the judgement to turn around matter as much as fitness, and there is no helicopter rescue above Base Camp.

Roughly 25 to 30 percent of climbers who attempt K2 reach the summit, against 50 to 65 percent on Everest. Historically its fatality rate ran near 23 to 25 percent, which is where the saying comes from that for roughly every four people who summited, one died. Better forecasting, fixed ropes and stronger high-altitude support have brought the modern figure down to roughly 12 to 13 percent. Recent counts put about 96 deaths against roughly 800 successful ascents. The worst single season was 1986, when 13 climbers summited and 13 died. The danger comes from objective hazards that fitness cannot remove: seracs above the Bottleneck that can collapse without warning, storms that pin climbers at high camps for days, and the death zone above 8,000 metres. Most accidents happen on the descent, not the summit, when climbers are exhausted and the weather is closing in, which is why we plan conservative turnaround times.

Our estimated cost for a fully supported K2 expedition starts at $55,000 per person, and we quote each expedition individually. Across the market, a commercial expedition typically runs from around $18,000 for a base-camp service up to $50,000-$100,000 or more for a fully supported package with oxygen and high-altitude staff. Part of that is the Pakistan mountaineering permit and the peak royalty paid to Gilgit-Baltistan, which generally fall between $6,000 and $12,000 per climber. Those fees have been in flux: Gilgit-Baltistan moved to sharply raise them in 2025, tour operators challenged the change in court, and a compromise structure now applies. Our price includes the permit and royalty, a liaison officer and base camp staff, all camps, tents and high-altitude equipment, supplemental oxygen and medical supplies, the Baltoro approach logistics and an experienced high-altitude team. International flights, travel insurance, personal expenses and personal climbing gear are not included. Custom expeditions are available for groups of 2 or more.

Plan on 60 to 70 days from arrival to departure. The walk in alone is about a week: from the jeep track at Askole the trail follows the Braldu River and the Baltoro Glacier for about seven days to Concordia, then a final day up to Base Camp, and that approach doubles as your first acclimatisation. Once at Base Camp, climbers spend several weeks making rotations, climbing to Camp 1, then Camp 2, sleeping high and dropping back down so the body adapts, with each rotation pushing a little higher before a final rest ahead of the summit bid. The rope-fixing team places lines on the steep sections early in the season, and that work often sets the rhythm for everyone. Then you wait, sometimes a fortnight, for a single safe summit window. The summit often comes down to a few hours of stable weather, so the length of the trip is what gives you a real chance.

The season runs June to August, and July and August give the only reliable windows. In high summer the Karakoram jet stream lifts north and opens short periods of stable weather, and the summit often comes down to a few hours of it. K2 is effectively unclimbable in spring. May, the prime month on Everest, brings deep snow and ferocious wind here. Winter ascents exist but belong to a tiny elite. The first was completed only in January 2021, when a Nepali team of 10 climbers led by Nirmal Purja and Mingma Gyalje Sherpa reached the summit on January 16. Because the window is so narrow, a full expedition runs 60 to 70 days: climbers need weeks of rotations between camps to acclimatise and then must wait, sometimes a fortnight, for a single safe summit window. Timing your arrival so you are acclimatised when that window opens is the whole game.

Yes. Everest is higher, but K2 is the harder and more dangerous climb. Its summit success rate is around 25 to 30 percent, against 50 to 65 percent on Everest, and its modern fatality rate is roughly 12 to 13 percent. Everest has fixed lines, ladders over the Khumbu Icefall, large commercial support and helicopter rescue to the lower camps. K2 has none of that safety net above Base Camp. The climbing is steeper and more sustained, the summit day longer and more exposed, and the margin for error far smaller. The Bottleneck at about 8,200m, a narrow ice couloir under hanging seracs, has no equivalent on the standard Everest route. The weather is harsher too: May, the prime month on Everest, brings deep snow and ferocious wind on K2. That is why operators expect a previous 8,000-metre summit before they take you, and why serious alpinists measure themselves against K2 rather than Everest.
