A climbing buddy once told me rankings are just opinions in a tuxedo. Fair enough. But this one shows its work, which makes it easier to argue with. Seven factors, each rated 1 to 10, each with a published weight that adds up to 100 percent.
The mountain that comes out on the gentle end is Cho Oyu, the easiest most difficult 8000m peak 8000m peak at 42.0. The one at the other end is K2, the hardest 8000m peak at 94.5. Let’s see what each factor actually measures and why some count more than others.
The Heavy Hitters
Technical Difficulty at 25 Percent
It covers steepness, rock, ice, fixed line movement and route finding. This gets the biggest weight, which is why Makalu and K2 climb so high. Cho Oyu scores a 3 here, while K2 scores 10. That one factor does a lot of the sorting.
Objective Hazard at 20 Percent
This one is about things you can’t control: avalanche, serac, rockfall and crevasse exposure. Annapurna gets a 10, and so does K2. Cho Oyu gets a 3, while Manaslu, with its avalanche exposure, gets a 6. It’s the factor that explains why a supported peak can still feel scary.
The Middle Weights
Weather and altitude each carry 15 percent. Weather covers wind, storms and how long and predictable the summit window is. Altitude covers summit height, death zone time and summit day exposure. Everest gets 10 for altitude, while K2 gets 9 and Cho Oyu 8.
Karakoram weather pushes up scores on Gasherbrum II (6) and Broad Peak (7). It’s why those mountains don’t rank as easily as their route descriptions suggest. A straightforward ridge in terrible weather is a different climb than the same ridge in a stable window.
The Small Weights
Remoteness and support gap each carry 10 percent. Remoteness looks at approach, evacuation, communications and rescue limits. Support gap grows when there are fewer ropes, operators, staff and shared resources. Everest scores 1 for support gap, but K2 scores 9.
Access is only 5 percent, deliberately small. Still, Shishapangma gets a 9 because permit availability can change the whole expedition, and Cho Oyu gets a 6. A mountain you may not be allowed to climb is, well, a problem no matter how gentle the slopes are.
Building Your Own Version
The source page includes a tool where you can change the weights yourself. The sliders are treated as relative values and normalized to 100 percent. Boost altitude and Everest climbs; boost support gap and the Karakoram mountains rise.
That’s a smart reminder that “easiest” depends on what you personally fear. If you worry about altitude, your 8000m peaks ranked by difficulty might shift. If crowding and logistics worry you, you’d weigh support gap differently. Your result is personal analysis, not a change to the published ranking.
Why the Hardest Mountain Wins Anyway
Even with different weights, K2 stays near the top because it scores 9 or 10 on almost everything except access. The hardest 8000m peak is hard from every angle, which is why reweighting rarely moves it far.
Meanwhile, the page cautions that gaps of one or two points are broadly similar. So the middle of the pack is open to debate, but the two extremes are pretty stable.
Conclusion
Seven factors, published weights and visible inputs make this model easy to inspect. Cho Oyu is the easiest 8000m peak and K2 the hardest 8000m peak, and the rest depends on which risks you care about most.
