Mountaineering is weird. People pay tens of thousands of dollars to suffer in thin air, eat freeze-dried mush, and potentially lose a toe to frostbite. But the allure of the Seven Summits—climbing the highest peak on every continent—remains the gold standard for high-altitude ambition. Here's the thing though: not all peaks are created equal. Some are basically a long, uphill walk in sneakers. Others are terrifying vertical labyrinths of ice and rock that want to kill you.
When people talk about the 7 summits in order of difficulty, they usually get into heated debates at base camp. Is Everest harder because of the altitude? Or is Vinson tougher because it’s at the bottom of the world? Honestly, difficulty is subjective. It depends on your fitness, the weather gods, and whether you’ve spent enough time training on technical terrain.
Let's break down the reality of these peaks, moving from the "entry-level" treks to the absolute monsters.
The "Easy" Wins: Kosciuszko and Kilimanjaro
Look, calling any mountain "easy" is a bit of a slap in the face to nature. But compared to the rest of the list, Mount Kosciuszko in Australia is a literal walk in the park. At 2,228 meters (about 7,310 feet), it's the lowest of the lot. Most people knock it out in a few hours. There’s even a metal walkway for a good chunk of it. If you can walk five miles on a slight incline, you’ve basically conquered an entire continent. Some purists argue for Puncak Jaya (Carstensz Pyramid) instead, but we’ll get to that complication in a bit.
Then there’s Kilimanjaro. This is the one everyone does for their 40th birthday. It’s the highest free-standing mountain in the world, sitting pretty in Tanzania. No technical climbing. No ropes. Just a lot of dusty trails and a very real chance of getting a pounding headache from the 5,895-meter altitude. The "difficulty" here isn't the terrain; it's the pace. If you go too fast, the mountain humbles you. The success rate hovers around 60-70% for a reason. People underestimate the thin air.
The Mid-Tier Grinds: Elbrus and Aconcagua
Mount Elbrus in Russia (Europe’s highest point) is where things start getting serious. It’s a massive double-coned volcano. While it's technically a "snow walk," the weather is notoriously fickle. One minute it's sunny, the next you're in a whiteout with 100 mph winds. You use crampons and ice axes here. It's a massive step up from a hike. You're dealing with 5,642 meters of elevation, and the cold can be bone-chilling.

Aconcagua is the big beast of South America. It towers at 6,961 meters. In the world of the 7 summits in order of difficulty, Aconcagua is often the "filter." It filters out the people who aren't ready for Everest. It’s non-technical if you take the Normal Route, but the "Viento Blanco" (white wind) is legendary. It’s essentially a high-altitude desert. It’s dry, it’s freezing, and the scree slopes will make you want to cry. You spend three weeks living in a tent. It’s a test of mental endurance more than anything else.
The Logistics Nightmare: Mount Vinson
Now we're getting into the expensive, remote stuff. Mount Vinson in Antarctica isn't necessarily the hardest climb technically, but it’s the most isolated. If something goes wrong, help is a long, long way away. You’re flying to the Union Glacier on a Russian Il-76 cargo plane.
The mountain is 4,892 meters high, but because it's near the pole, the barometric pressure makes it feel much higher. The cold is relentless. We’re talking -40 degrees on a "nice" day. You’re pulling a sled with all your gear across the ice. It’s beautiful, pristine, and incredibly intimidating. It requires solid glacier travel skills and the ability to survive in a freezer for two weeks.
The Technical Gatekeeper: Puncak Jaya (Carstensz Pyramid)
This is the outlier. Located in the Papua province of Indonesia, Puncak Jaya is a jagged limestone tooth sticking out of the jungle. If you follow the "Messner list" of the Seven Summits, this is the one that replaces Kosciuszko. It is arguably the most technical of all of them.
You aren't walking up snow here; you’re rock climbing. There’s a famous Tyrolean traverse—basically a high-wire act across a deep chasm—that terrifies most climbers. Getting to the base is a nightmare involving either a helicopter or a grueling multi-day trek through dense jungle. It’s sharp, it’s wet, and it requires actual mountaineering skill.

The Top Tier: Denali and Everest
Many professional guides will tell you that Denali (Mount McKinley) in Alaska is actually harder than Everest. Why? Because you have to do everything yourself. On Everest, Sherpas carry most of the heavy loads. On Denali, you are the pack mule. You’re caching food, hauling a 60-pound pack, and pulling a 40-pound sled.
The weather on Denali is some of the worst on the planet. It’s a 6,190-meter peak with the vertical gain of an 8,000-meter peak because the base camp is so low. It’s a brutal, exhausting, soul-crushing climb that requires elite fitness.
Then, there’s Everest. 8,848 meters. The Death Zone.
Is it the most technical? No. But the sheer altitude makes it the ultimate boss. Above 8,000 meters, your body is literally dying. Every step takes ten breaths. You’re navigating the Khumbu Icefall, which is a shifting labyrinth of giant ice blocks. You’re dealing with crowds, which adds a layer of danger people don't like to talk about. Even with bottled oxygen, it’s a massive undertaking.
Why the Order Changes
Context matters. If you climb Everest in a "good" year with perfect weather, it might feel easier than a storm-battered Denali. If you’ve never put on a climbing harness, Puncak Jaya will be your Everest.

Most people tackle them in this general progression:
- Kosciuszko (The easy warm-up)
- Kilimanjaro (The altitude test)
- Elbrus (The snow skills test)
- Aconcagua (The endurance test)
- Denali or Vinson (The cold/expedition test)
- Everest (The ultimate goal)
Practical Reality Check
Before you go booking a flight to Nepal or Tanzania, look at your resume. High-altitude mountaineering isn't something you "wing."
- Training: You need a mix of zone 2 aerobic base training and weighted carries. Hiking uphill for 6 hours with 50 lbs in your pack is the only way to simulate the strain.
- Gear: Don't skimp. A cheap sleeping bag on Aconcagua is a recipe for a miserable night. You need layers that work together—wicking, insulating, and shielding.
- Guides: Unless you are an expert, hire a reputable company like Alpine Ascents or Adventure Consultants. They know the terrain and, more importantly, they know when to turn back.
The biggest mistake people make is thinking they can buy their way to the top. Money buys the gear and the guides, but it doesn't buy the red blood cells or the mental toughness needed when you're puking in a tent at 20,000 feet. Start small. Learn how your body reacts to 14,000 feet before you try 20,000.
Your Next Steps
If you're serious about the Seven Summits, start by booking a local mountaineering course. Learn the basics of self-arrest with an ice ax and how to walk in crampons without stabbing yourself in the calf. Once you have the skills, look at Kilimanjaro or Elbrus as your first "real" expedition. They provide the best feedback on how your body handles oxygen deprivation without the extreme technical risks of the higher peaks. Track your heart rate, understand your hydration needs, and build a foundation. The mountains aren't going anywhere.
