Mount Everest: The Highest Peak in the World

Mount Everest is the highest mountain on Earth, rising to 8,848.86 meters (29,031.7 feet) above sea level. Located on the Nepal–Tibet border at coordinates 27.9881°N, 86.9250°E, Everest is the defining peak of the Mahalangur Himal sub-range of the Himalayas — and the ultimate goal for mountaineers, trekkers, and adventurers worldwide.

Known as Sagarmatha in Nepal and Chomolungma in Tibet, the mountain was first summited on May 29, 1953, by Sir Edmund Hillary and Tenzing Norgay Sherpa. Since then, approximately 7,200 different climbers have reached the summit across roughly 13,000 total ascents, while hundreds of thousands more have trekked to Everest Base Camp to witness the mountain up close.

Whether you plan to summit, trek, or simply understand this iconic peak, this guide covers everything: exact location and coordinates, official height, geology, weather, climbing routes, permits, costs, records, environmental challenges, and essential facts.

Where Is Mount Everest Located?

Mount Everest is located in the eastern Himalayas of Asia, sitting precisely on the international border between Nepal (to the south) and the Tibet Autonomous Region of China (to the north).

Nepal side: The southern face lies within Solukhumbu District and Sagarmatha National Park, a UNESCO World Heritage Site. This is the most visited side, home to the legendary Everest Base Camp trek.

Tibet side: The northern face lies in Tingri County, Xigazê Prefecture. The North Base Camp is accessible by road from Lhasa, making it popular for drive-in visitors.

The summit itself sits directly on the border line. Because Nepal offers richer trekking infrastructure, Sherpa culture, and established expedition routes, it is the more popular approach for both trekkers and climbers.

Neighboring Peaks

Everest does not stand alone. The Mahalangur Himal section of the Himalayas contains several of the world's tallest mountains in close proximity:

• Lhotse — 8,516 m (4th highest on Earth), sharing Everest's South Col
• Nuptse — 7,861 m, forming the iconic three-peak ridge visible from Base Camp
• Makalu — 8,485 m (5th highest), 19 km southeast of Everest
• Cho Oyu — 8,188 m (6th highest), 30 km to the west

How High Is Mount Everest?

Mount Everest stands at an officially recognized height of 8,848.86 meters (29,031.7 feet) above sea level. This measurement was jointly confirmed by Nepal and China in December 2020 using modern GPS technology and ground-penetrating radar — the most precise survey ever conducted.

History of Everest's Height Measurements

Measuring the world's highest mountain has evolved significantly over 170 years:

• 1856: The Great Trigonometric Survey of India calculated the height at 8,840 m (29,002 ft), designating it "Peak XV"
• 1955: An Indian survey updated the figure to 8,848 m (29,029 ft), accepted for decades
• 1999: A U.S. GPS survey found 8,850 m (29,035 ft)
• 2005: A Chinese survey measured 8,844 m (29,017 ft), measuring only the rock summit
• 2020: Nepal and China jointly confirmed 8,848.86 m — now the globally accepted standard

Is Mount Everest Still Growing?

Yes. The Himalayas continue to evolve due to the ongoing collision of the Indian tectonic plate and the Eurasian plate. This tectonic pressure pushes Everest upward by approximately 4 millimeters (0.16 inches) per year. At the same time, erosion by ice, wind, and weather works against this growth, keeping the mountain's net height relatively stable over human timescales.

Geology of Mount Everest

The story of Mount Everest begins approximately 50–60 million years ago, when the Indian tectonic plate began colliding with the Eurasian plate. This "continental collision" — one of the most powerful geological forces in Earth's history — pushed ancient ocean-floor sediments skyward to form the Himalayan mountain range.

One of the most remarkable geological facts about Everest: the rocks at the summit are composed of marine limestone. In other words, the highest point on Earth was once part of an ancient ocean floor. Fossils of sea creatures have been found in Himalayan rock, embedded in stones now sitting above 8,000 meters.

The Himalayas began rising approximately 25–30 million years ago and took their current form during the Pleistocene Epoch (roughly 2.6 million to 11,700 years ago). The mountain system remains geologically active and seismically dynamic today, as evidenced by the devastating 2015 Nepal earthquake.

Mount Everest's Names and Cultural Significance

1. Sagarmatha — Nepal

In Nepal, Everest is called Sagarmatha, often translated as "Peak of Heaven" or "Forehead of the Great Blue Sky." The name reflects the mountain's spiritual importance in Nepali culture and national identity. Sagarmatha is also the name of the UNESCO-listed national park that protects the surrounding region.

2. Chomolungma — Tibet

In Tibet, the mountain is called Chomolungma (also spelled Qomolangma), meaning "Goddess Mother of the World" or "Goddess of the Valley." For Tibetan Buddhists, the mountain is considered the sacred home of Miyolangsangma, a goddess of prosperity and good fortune.

3. The Western Name: Everest

The English name was assigned in 1865 by British surveyor-general Sir Andrew Waugh, who named the peak in honor of his predecessor Sir George Everest, Surveyor General of India from 1830 to 1843. The correct pronunciation of Everest's name was "EVE-rest," though it is widely mispronounced today.

The Puja Ceremony

Before every expedition, Sherpa guides and climbing teams gather at Base Camp for a puja ceremony — a traditional Buddhist ritual in which a lama blesses the climbers, their equipment, and the journey ahead. The ceremony asks Chomolungma for permission and safe passage. Even non-religious climbers participate, both out of respect and as a meaningful way to mark the gravity of what lies ahead.

Weather and Climate on Mount Everest

The weather on Mount Everest is among the harshest on Earth, characterized by extreme cold, hurricane-force winds, and rapidly changing conditions.

Temperature

Location	Summer (July)	Winter (January)
Summit (~8,849 m)	Around –19°C (–2°F)	Around –36°C (–33°F)
Base Camp (~5,364 m)	2°C to 10°C	–15°C to –25°C

Wind

The jet stream is one of Everest's most dangerous elements. When it dips south over the mountain, winds can exceed 280–320 km/h (175–200 mph) — strong enough to throw climbers off the mountain. During the brief spring and autumn climbing windows, the jet stream typically shifts northward, allowing periods of relative calm.

Even in favorable conditions, sustained winds at the summit often reach 160 km/h (100 mph). Modern meteorological forecasting has dramatically improved the ability of expedition teams to identify safe weather windows, but Everest remains highly unpredictable.

Best Time to Visit Mount Everest

• Spring (March–May): Primary climbing season. The jet stream shifts north, offering the best weather windows for summit attempts.
• Summer/Monsoon (June–September): Heavy precipitation, poor visibility, high avalanche risk. Not recommended for climbing or trekking.
• Autumn (September–November): Second-best trekking season. Stable weather, clear skies, less crowded than spring.
• Winter (December–February): Extremely harsh. Temperatures at the summit can drop below –60°C, with winds exceeding 160 km/h. Very few climbers attempt Everest in winter.

How to Reach Mount Everest?

Step 1: Fly to Kathmandu

Almost all visits to Everest begin with a flight to Kathmandu, the capital of Nepal. Tribhuvan International Airport serves direct flights from major Asian hubs and connects to global routes via layovers in Delhi, Doha, Dubai, and Bangkok.

Step 2: Fly to Lukla

From Kathmandu, you take a flight to the gateway to Everest, the mountain town of Lukla (elevation 2,860 m / 9,383 ft). During peak trekking seasons, some flights operate from Manthali Airport (Ramechhap) instead, reducing air traffic congestion. The Lukla landing strip — perched on a mountain ledge — is consistently ranked among the world's most challenging airports.

Step 3: Trek to Everest Base Camp

The classic Everest Base Camp (EBC) trek covers approximately 130 km (80 miles) round trip over 12–14 days, gaining altitude steadily to acclimatize safely. The trail passes through iconic Sherpa villages, alpine forests, and dramatic Himalayan terrain.

Key stops on the classic EBC route:

• Phakding (2,652 m) — First overnight stop after Lukla
• Namche Bazaar (3,440 m) — The Sherpa capital; key acclimatization point (2 nights recommended)
• Tengboche (3,860 m) — Famous monastery with direct views of Everest, Lhotse, and Ama Dablam
• Dingboche (4,410 m) — Second acclimatization stop (2 nights recommended)
• Lobuche (4,940 m) — High-altitude camp with stark lunar landscapes
• Gorak Shep (5,164 m) — Last village; jumping-off point for Base Camp
• Everest Base Camp (5,364 m) — The foot of the mountain; views of the Khumbu Icefall

Optional side trip from Gorak Shep: Kala Patthar (5,545 m) offers the most accessible panoramic view of Everest's summit from the Nepal side.

Step 4: Climb from Base Camp to Summit

After reaching Everest Base Camp, climbers begin their summit attempt by acclimatizing through rotations to higher camps.

Camp I at the Khumbu Icefall (6,065 m) is the first stop, followed by Camp II at the South Col (6,400 m) and Camp III on the Lhotse Face (7,200 m). Camp IV at the South Col (7,900 m) serves as the final staging point before the summit push.

Climbers usually start late at night from Camp IV to reach the summit in the early morning, relying on fixed ropes and supplemental oxygen. Once at the top, a safe descent to lower camps is critical, as most accidents occur on the way down. Timing, weather conditions, and guidance from experienced Sherpas are essential for a successful climb.

Climbing Mount Everest: Everything You Need to Know

Is Everest a Beginner Climb? No. Mount Everest demands advanced mountaineering experience, exceptional fitness, and years of preparation. It is not a peak for aspiring climbers new to high-altitude or technical terrain. Most operators require climbers to have previously summited at least one major 7,000 m+ peak, and ideally an 8,000 m peak such as Island Peak, Mera Peak, or Ama Dablam at minimum.

The Two Main Climbing Routes

1. Southeast Ridge Route (Nepal / South Col) The most popular route, pioneered by Hillary and Norgay in 1953. Starting from South Base Camp (5,364 m), climbers move through:

• Khumbu Icefall — One of the most dangerous sections; a constantly moving glacier riddled with crevasses and unstable ice towers (seracs)
• Western Cwm — A high glacial valley leading to Camp 2
• Lhotse Face — A steep 1,100 m ice wall to Camp 3
• South Col (7,906 m) — Camp 4; the launching pad for summit day
• Southeast Ridge and Hillary Step — The final technical section before the summit

2. North Ridge Route (Tibet)

The first approach was attempted by Western expeditions in the 1920s. Accessed from North Base Camp in Tibet (~5,150 m), this route traverses the Northeast Ridge and passes through the famous "three steps." It is technically more demanding in sections but avoids the Khumbu Icefall.

The Camp System (Nepal Side)

Camp	Elevation	Purpose
Base Camp	5,364 m (17,598 ft)	Expedition hub; acclimatization
Camp 1	~6,065 m (19,900 ft)	Above the Khumbu Icefall
Camp 2 (Advanced Base)	~6,400 m (21,000 ft)	Main rest point in Western Cwm
Camp 3	~7,200 m (23,600 ft)	On the Lhotse Face
Camp 4 (South Col)	~7,906 m (25,938 ft)	Summit launch point
Summit	8,848.86 m (29,031.7 ft)

The Death Zone

Above 8,000 meters (26,247 feet), the human body enters the "death zone" — where oxygen levels are so low (approximately one-third of sea-level oxygen) that cells begin dying faster than they can be replenished. Even with supplemental oxygen, climbers deteriorate rapidly above this altitude. Cognitive impairment, hallucinations, frostbite, and pulmonary or cerebral edema become serious risks.

Most climbers carry 4–6 oxygen cylinders for summit day and high camps. In 1978, Reinhold Messner and Peter Habeler made history by completing the first ascent without supplemental oxygen — a feat many physiologists thought impossible. Messner then completed the first solo ascent in 1980.

Permits and Regulations

Climbing Everest from Nepal requires a government permit, currently costing approximately USD $15,000 per climber (South-East Ridge/Normal Route) in the spring season. It costs USD 7,500 (Autumn) and USD 3,750 (Winter/Monsoon). For Nepali citizens, the permit cost is 150,000 NPR (Spring). Nepal introduced major regulatory reforms:

• Mandatory guide ratio: Every two foreign climbers must be accompanied by one certified Nepali climbing guide or Sherpa
• Stricter waste requirements: Each climber must return at least 8 kg of waste from above Base Camp
• Fitness screening: Applicants may face enhanced experience vetting

On the Tibet (China) side, the permit structure and access rules differ and are subject to separate regulations.

How Long Does It Take to Climb Everest?

A complete Everest expedition — from arrival in Nepal to departure — typically takes 6 to 9 weeks or 50-60 days. This includes:

• Travel and acclimatization in Kathmandu
• Trek to Base Camp (~10–12 days)
• Multiple rotation climbs between Base Camp and higher camps (4–5 weeks)
• Waiting for a summit weather window
• Summit push (~2–4 days from Camp 4)
• Descent and departure

How Much Does Climbing Everest Cost?

The total cost of an Everest expedition varies widely:

Budget Tier	Estimated Cost
Budget expedition (minimal support)	USD $30,000–$45,000
Mid-range commercial expedition	USD $45,000–$65,000
Full-service Western-guided expedition	USD $70,000–$120,000+

Costs include: climbing permit, expedition logistics, Sherpa and guide fees, oxygen systems, high-altitude gear, insurance, accommodation, and flights.

The Mallory and Irvine Mystery

On June 8, 1924, British climbers George Mallory and Andrew Irvine disappeared high on Everest's Northeast Ridge during a summit attempt. Whether they reached the top — 29 years before Hillary and Tenzing — remains one of the great unsolved mysteries of mountaineering. Mallory's body was discovered in 1999. In 2024, Irvine's detached foot, still inside a boot and sock, was recovered, reigniting debate about what happened to the pair.

Sherpa People and the Human Story of Everest

The Sherpa people of the Khumbu region are central to every Everest expedition. Long before Everest became a global climbing destination, Sherpas revered Chomolungma as a sacred home of Buddhist deities. Today, they serve as high-altitude guides, load carriers, route fixers, and rescuers.

Kami Rita Sherpa holds the all-time record with 31 summit ascents, a testament to the physical and cultural connection Sherpas have with the mountain. A typical Sherpa guide might earn USD $5,000–$7,000 for a two-month expedition — a substantial income in rural Nepal, but modest compared to what Western guide companies charge clients.

No Everest expedition is complete without the puja ceremony, where a Buddhist lama blesses the team and their equipment before climbing begins. This is not merely tradition — it reflects the deeply held spiritual belief that the mountain is alive and must be approached with humility and reverence.

Environmental Challenges on Everest

Decades of mountaineering activity have left a significant environmental footprint on Everest.

The Waste Problem

Each expedition generates oxygen bottles, food packaging, camping equipment, and human waste. Critics have called Everest "the world's highest garbage dump." Nepal's 8 kg waste return policy has helped, and the spring 2024 cleanup campaign removed over 10,000 kilograms of trash from the mountain's slopes. However, the challenge remains ongoing.

Climate Change and the Khumbu Glacier

The Khumbu Glacier, which flows from the Khumbu Icefall past South Base Camp, is retreating and thinning rapidly due to climate change. This destabilization has made certain sections of the glacier more unpredictable and dangerous. Nepal's government has been considering moving South Base Camp to a lower elevation, though as of 2025, the move has been delayed due to logistical challenges and resistance from the climbing community.

What to See in the Everest Region?

The Everest region offers far more than the mountain itself:

• Namche Bazaar (3,440 m) — The "Gateway to Everest" and the Sherpa capital, with markets, cafes, a museum, and stunning mountain views
• Tengboche Monastery — One of the most important Buddhist monasteries in Nepal, set against a backdrop of Everest, Lhotse, and Ama Dablam
• Sagarmatha National Park — A UNESCO World Heritage Site protecting snow leopards, red pandas, Himalayan tahr, and ancient forest
• Gokyo Valley — A stunning alternative to EBC, featuring turquoise glacial lakes and views of five 8,000 m peaks from Gokyo Ri
• Kala Patthar (5,545 m) — The most popular summit viewpoint for non-climbers, offering one of the best photographs of Everest
• Imja Tse / Island Peak (6,189 m) — A popular technical peak for climbers who want to experience high-altitude mountaineering without attempting Everest itself

Final Thoughts

Mount Everest is far more than the world's highest mountain. It is a place where geology, weather, culture, human ambition, and ecological fragility converge in one of the most dramatic landscapes on Earth. For the Sherpa people, it is a sacred home. For Nepal, it is a symbol of national identity.

For climbers, it is the ultimate test. For the hundreds of thousands who trek through the Khumbu region each year, it is an experience that permanently changes one's sense of scale — of nature, of effort, and of what is possible.

Whether you come to summit, trek, photograph, or simply understand this extraordinary peak, Everest rewards every level of engagement with a depth that few places on Earth can match.

FAQs

Which country is Mount Everest in?

Mount Everest straddles the border between Nepal (south side) and the Tibet Autonomous Region of China (north side). The summit sits precisely on the international boundary.

What is the exact height of Mount Everest?

The official height is 8,848.86 meters (29,031.7 feet) above sea level, confirmed by a joint Nepal–China survey in December 2020.

Who first climbed Mount Everest?

Sir Edmund Hillary of New Zealand and Tenzing Norgay Sherpa of Nepal/India made the first confirmed successful ascent on May 29, 1953.

Can you visit Everest without climbing it?

Yes. The Everest Base Camp trek is one of the world's most famous trekking journeys and requires no technical climbing skills. Helicopter tours and mountain flights from Kathmandu are also popular options.

Is Mount Everest visible from Kathmandu?

No. Everest is not visible from Kathmandu due to distance and intervening ridges. The best way to see it from Kathmandu is via a mountain flight or by traveling into the Khumbu region.

What is the death zone on Everest?

The "death zone" refers to elevations above 8,000 meters (26,247 feet), where atmospheric oxygen is so thin that the body deteriorates faster than it can recover. Even with supplemental oxygen, climbers must minimize time spent above this altitude.

Is Everest the tallest mountain on Earth?

Everest is the highest mountain above sea level. Measured from base to summit, Mauna Kea in Hawaii is taller (over 10,000 m when measured from the ocean floor). Measured from Earth's center, Mount Chimborazo in Ecuador is farther from the Earth's core due to the equatorial bulge. But by the universally accepted measure of elevation above sea level, Everest is definitively the highest point on Earth.
