Mount Everest Climbing Guide 2026: Routes, Cost & Rules

The Mountain: The Roof of the World

Mount Everest straddles the border of Nepal and Tibet (China) in the Himalaya, rising to 8,848.86 m — the highest point on the surface of the Earth. The Nepalis call it Sagarmatha (“forehead of the sky”); to Tibetans it is Chomolungma (“mother goddess of the world”). It was first climbed in 1953 by Edmund Hillary and Tenzing Norgay Sherpa, and in the seven decades since, it has gone from the preserve of national expeditions to the most commercially guided major peak on the planet.

Everest is not, by modern standards, a technically extreme climb — there is no single hard pitch like K2’s Bottleneck or the Eiger’s North Face. What makes it lethal is altitude. Above 8,000 m lies the “death zone,” where the air holds roughly a third of the oxygen at sea level and the human body is actively dying. Climbers move on bottled oxygen, supported by Sherpa teams and a chain of camps, and even then the margins are thin: weather, exhaustion, frostbite, altitude illness, and the objective hazards of the Khumbu Icefall claim lives nearly every season. It is, in the truest sense, a feat of endurance and logistics more than of pure technical skill.

It is also the most crowded it has ever been. Nepal issued a record 492 Everest permits for 2026, and with the Tibetan side closed, every one of those climbers funnels onto the South Col route — making the choice of operator, weather window, and timing more consequential than ever.

What Changed for 2026

Everest’s rules were overhauled for the 2025-2026 seasons in response to overcrowding, deaths, and the mountain’s mounting waste problem. If your knowledge of climbing Everest is more than a year or two old, much of it is now out of date. The headline changes:

The Routes: South Col vs North Ridge

Everest has two principal routes, one from each country. For 2026 the choice is effectively made for you — but it’s worth understanding both. Our South Col vs North Ridge comparison goes deeper.

The Climb, Camp by Camp

The South Col route is a slow, staged ascent built around acclimatization. Climbers don’t go straight up; they make repeated rotations between camps over weeks, letting their bodies adapt before a final push timed to a narrow weather window — usually in mid-to-late May. Here is the chain from bottom to top:

Cost Breakdown (2026)

Everest is one of the most expensive mountains in the world to climb, and 2026 made it more so. The headline number — the permit — is only a fraction of the total. Where you land in the range depends almost entirely on the operator tier you choose. Full detail in our cost & permits guide.

Success Rates & Who Climbs It

In the modern guided era, roughly 60-65% of climbers who attempt Everest reach the summit — about 61% in recent seasons — a far cry from the early decades when success was rare. The improvement comes from better weather forecasting, fixed ropes installed the length of the route, ample bottled oxygen, and strong Sherpa support. But the average hides wide variation: a fit, well-acclimatized client with a top-tier operator and patient weather strategy has far better odds than a rushed climber on a budget trip in a bad season. Our summit success-rate guide breaks the numbers down by year and conditions.

Danger & the Death Zone

For all its commercialization, Everest kills. More than 300 climbers have died on the mountain since the 1920s, and an estimated 200-plus bodies remain on its slopes – too dangerous or costly to recover. Recent seasons have ranged from a handful of deaths to the 17-18 lost in the deadly spring of 2023. In relative terms Everest’s fatality rate is only about 1% in the modern era – low for an 8000er, yet the highest total death toll of any mountain; we rank the peaks in most dangerous mountains and death rates by mountain.

The core danger is the death zone above 8,000 m, where the air holds about a third of sea-level oxygen and the body deteriorates by the hour despite weeks of acclimatization. Most deaths come from a combination of altitude illness (HAPE and HACE), exhaustion, frostbite, falls on the descent, avalanches, and collapse in the Khumbu Icefall. Crucially, the descent is more dangerous than the ascent: many climbers die after summiting, out of oxygen and energy, caught by weather or darkness.

Best Time to Climb

The overwhelming majority of ascents happen in the spring pre-monsoon season (April-May), with the summit window typically falling in mid-to-late May, once the Sherpa teams have fixed ropes to the top and a stable, low-wind weather window opens. The expedition itself starts weeks earlier, in April, to allow for acclimatization rotations. A small autumn (post-monsoon) season exists but is colder, snowier, and far less popular. Winter and summer ascents are the realm of elite specialists. Patience is part of the strategy: operators wait, sometimes for weeks, for the right window – and the climbers who summon the discipline to wait are the ones who summit safely.

Experience & Prerequisites

Everest is not a first big mountain. Reputable operators – and increasingly Nepali law – expect a serious mountaineering resume before they’ll put you on it:

• Prior high-altitude experience – typically a 6,000 m and ideally an 8,000 m peak (such as Manaslu or Cho Oyu – see the 14 eight-thousanders) before attempting Everest.
• Technical competence – fixed-rope ascending and descending, crampon and ice-axe skills, ladder crossings, and self-care at extreme altitude.
• Serious aerobic fitness – built over 9-12+ months, capable of sustained effort for weeks in thin air.
• A current medical certificate – now mandatory, including cardiac screening.
• The coming Nepal 7,000 m rule – approved in legislation; plan a qualifying Nepali 7,000 m summit if Everest is a future goal.

The Sherpas Behind Every Summit

No honest Everest guide is complete without this: the mountain is climbed on the backs of Sherpas and other Nepali high-altitude workers. They fix the ropes, carry the loads, build the camps, break trail through the Khumbu Icefall, and shoulder the greatest share of the risk – making more trips through the most dangerous terrain than any client. Their pay, conditions, and the economics of the expedition industry are a story in themselves, and one of the most-read on this site: our deep dive into the Sherpa wage economy lays out what they actually earn and why it matters. Choosing an operator that pays, equips, and insures its Nepali staff well is both an ethical and a safety decision.

Gear & Oxygen

Everest demands a full 8,000 m kit: a one-piece down summit suit, 8,000 m boots, a high-altitude sleeping system, and the personal technical gear for fixed-rope travel – plus the bottled supplemental oxygen that nearly all climbers use above Camp III. The volume of oxygen your package includes is one of the biggest safety variables on the mountain. The complete list is in our Everest gear list.
