Standing as titans of the mountain world, scaling Everest or K2 is a dream for many adrenaline-seeking trekkers. But in the age-old debate of whether it’s more difficult to conquer K2 or Everest, which reigns supreme?
The truth is that both have treacherous terrains, unpredictable weather, chilling temperatures, and dangerous physical demands. Let’s break down the technicalities and dangers involved in expeditions to Everest and K2.
Standing at 8,849m (29,032 ft) above sea level, Everest holds the title of the tallest mountain in the world, enticing thousands of mountaineers around the world. K2, the runner-up, stands tall at 8,611m (28,251 ft) in Pakistan's northern region. While Everest may be the undisputed king, K2's reputation for difficulty makes it a coveted challenge for many.
There have been more successful summits of Everest than K2, the so-called “Savage Mountain”. This is largely because of the unforgiving topography of K2, with a relentlessly steep ascent and very few sections offering a break from the incline. In contrast, Everest has steeper sections but also plateaus that provide climbers with periods of relative ease.
Let’s compare the two in more detail.
K2 is generally considered to be the most difficult among the 8000m peaks due to its many technicalities. This expedition requires climbers with a high level of skill and experience in ice and mountain climbing.
The most popular route is the Abruzzi Spur, or the Southeast Ridge, which begins on the Pakistani side of the mountain. Presented with several technical and exposed sections, as climbers trek towards the summit, they will have to navigate over a 100ft crack also known as “House Chimney” and then almost vertically climb up a steep, rocky and icy section known as the “Black Pyramid”.
Even when the summit is near in sight, there is still another challenge to overcome. Located at 8,200m, lies the infamous Bottleneck, a thin couloir — a narrow gully with a steep incline — on the eastern border. Add to this towering columns of glacial ice known as seracs that precariously overhang the Bottleneck. The combination of the elevation, its steep slope (50-60 degree traverse), and the significant risk of avalanches and falling rocks makes the Bottleneck the most dangerous part of the world’s deadliest mountain.
While K2 boasts the steeper slopes, Everest presents its own set of challenges. The unforgiving terrain, a chaotic mix of ice, rock, and snow, coupled with constant exposure on steep slopes and hidden crevasses, makes this climb a gruelling test of physical and mental fortitude.
While Everest has more established routes with fixed ropes and ladders, climbers are still faced with a giant hurdle — The Khumbu Icefall. Notorious for being one of the most dangerous parts of the climb, this river of constantly moving ice sits 5,500 to 5,800m above Base Camp. Its reputation stems from more than just the danger it poses, but also the lives it has claimed. That is why climbers need to be well-prepared beforehand to navigate the icefall.
Elite Exped's guides are Khumbu Icefall experts. Their countless crossings have instilled an intimate knowledge of the terrain, allowing them to navigate safely and ensure your well-being throughout the climb.
Despite Everest's higher altitude, K2's northerly location exposes it to harsher conditions. Stronger winds and colder temperatures elevate the risk of frostbite and hypothermia. K2's notorious weather can transform clear skies into whiteout blizzards in minutes, demanding exceptional judgment and rapid adaptation. Thankfully, summer offers the most favourable window for summit attempts.
As Nimsdai notes, there are countless reasons why for many years K2 remained the only 8000m peak to not be climbed during the winter season. It's not just the brutally steep slopes and constant exposure; K2 wages a relentless war with weather year-round. Imagine battling hurricane-force winds, still-air temperatures plummeting below -65°C, and the suffocating thin air caused by low barometric pressure at high altitudes. Little wonder these conditions have historically deterred climbers and made winter expeditions seem impossible.
Everest also throws unpredictable and ferocious weather at climbers. Blizzards, winds exceeding 200mph, and temperatures plummeting below -40°C should be expected – sometimes all within a few short hours.
At Elite Exped, our years of experience guiding climbers through these extremes come into play. While spring offers the most stable window, with winter's wrath receding and minimal rain, even then, Mother Nature can be unpredictable in the world's harshest environment. However, we can guarantee you'll be in the safest possible hands when the unexpected arises.
Both expeditions are a significant climbing endeavour for any mountaineer, regardless of prior experience. All climbers will need to be in excellent physical condition to tackle the challenges of their chosen expedition. For both K2 and Everest, most expedition leaders will expect you to have experience climbing at least one other 8,000m peak.
Furthermore, K2 and Everest treks require cardiovascular and strength endurance. You will need to undergo aerobic training and strength conditioning before climbing either mountain. Here at Elite Exped, we have forged a unique partnership with The Altitude Centre who help climbers gain the required fitness levels faster and offer acclimatisation training to get you ready for ascent.
We also strongly recommend seeking medical advice before deciding to arrange your trek and before starting a training program, particularly if you have any concerns about your health.
While K2 is technically the hardest mountain to climb, don't underestimate Everest's perils. Yet, for those who conquer these giants, the reward is unlike any other: the privilege of standing atop the world, gazing upon a vista that humbles and inspires in equal measure.
We offer multiple expedition packages including our Everest Expedition and K2 Expedition. Both require a significant time commitment, but we do offer Everest Fast-Track and K2 Fast-Track expeditions for those with busy professional lives or limited time for any other reason.
Alternatively, we offer K2 & Broad or Everest and Lhotse combo packages for those looking to tick two 8,000m peaks off their bucket lists in one go. Or, if you’re still working on your levels of endurance and experience, we offer a trek to Everest Base Camp, offering you unparalleled views of the world’s highest mountain.
