Mount Everest – Height, Costs, Deaths & Key Facts 2025

Rising above the Himalayan ridge that separates Nepal and Tibet, Mount Everest has long held the title of the world’s highest peak above sea level. Its official height, measured jointly by Nepal and China in 2020, stands at 8,848.86 meters (29,031.7 feet). The mountain, known as Sagarmāthā in Nepal and Qomolangma in Tibet, remains both a powerful draw for climbers and a site of ongoing environmental and geopolitical pressures.

In 2025, Everest is as commercialized as ever. Expedition costs range from roughly $35,000 to well over $100,000, depending on route, level of support, and whether the climb is guided or fully custom. Over 6,000 people have summited the mountain as of 2023, but more than 300 have died trying. The combination of extreme altitude, crowded summit windows, and unpredictable weather continues to define the Everest experience.

This guide covers the essential facts about Everest: its height, location, climbing routes, costs, history, and the risks that climbers face. All data is drawn from verified sources, including official surveys, mountaineering databases, and recent reporting.

Where Is Mount Everest Located?

Mount Everest lies in the Mahalangur Himal range of the Himalayas. Its summit marks part of the border between Nepal to the south and the Tibet Autonomous Region of China to the north. The coordinates are approximately 27°59′ N, 86°56′ E. Everest was first identified as the world’s highest peak in the mid-19th century by surveyors working for British India, according to Britannica.

Because the mountain straddles two countries, climbers must choose their approach accordingly. The southern side is accessed from Nepal, while the northern side is accessed from Tibet. Each side has its own permit system, logistical requirements, and climbing route.

Names and cultural significance

In Nepal, the mountain is called Sagarmāthā, meaning “forehead in the sky.” In Tibet, it is known as Qomolangma or Chomolungma, which translates to “goddess mother of the world.” The English name Mount Everest was adopted in 1865, honoring Sir George Everest, the British Surveyor General of India at the time.

How Much Does It Cost to Climb Mount Everest?

The cost of climbing Everest varies widely depending on the route, the operator, and the level of support. In 2025, a basic supported climb from the Nepal side typically runs between $35,000 and $45,000, according to Climbing.com. More comprehensive expeditions can reach $55,000 to $100,000 or more, with fully custom trips going beyond $115,000.

A single climbing permit from Nepal costs $11,000 per person. That fee covers only permission to climb. The total expedition price includes permits, guides, Sherpa support, oxygen tanks, logistics, food, transport to base camp, and rescue contingencies. Budget-conscious climbers might find stripped-down options starting at around $25,000, but these come with fewer services and higher personal risk.

The Nepal versus China side

Climbing from the Nepal side via the South Col route is the most popular option and generally cheaper in terms of logistics. The Tibet side, using the North Ridge route, requires permits from Chinese authorities and involves longer approach travel. Prices on both sides have risen steadily in recent years due to demand and regulatory changes.

Who Was the First Person to Climb Mount Everest?

The first confirmed ascent of Mount Everest took place on 29 May 1953. Edmund Hillary of New Zealand and Tenzing Norgay, a Sherpa from Nepal, reached the summit via the South Col route from the Nepal side. Their achievement was widely celebrated and marked the culmination of decades of British and international exploration.

Other notable firsts include Junko Tabei of Japan, who became the first woman to summit Everest on 16 May 1975. In 1980, Reinhold Messner completed the first solo ascent of the mountain and did so without supplementary oxygen, a feat that remains extremely rare. As of 2023, only about 200 climbers have reached the summit without bottled oxygen, according to the Himalayan Database.

How Many People Have Died on Mount Everest?

The total number of deaths on Everest is difficult to pin down with precision because different sources use different cut-off dates. One widely cited count puts the figure at 340 deaths as of May 2024, while another report tallies 335 deaths through December 2024. Both figures are consistent with the understanding that Everest has caused more than 300 deaths overall.

The most common causes of death include avalanches, falls, altitude sickness or hypoxia, exposure, exhaustion, and hypothermia. The Khumbu Icefall, a constantly shifting glacier on the Nepal side, is considered one of the most dangerous sections of the climb. A 2025 analysis by Alan Arnette’s Everest coverage lists avalanches, falls, altitude sickness, and exposure as the top four causes from 1922 to 2024.

The death zone explained

The death zone is generally considered to begin above 8,000 m (26,247 ft). At that altitude, oxygen levels are too low for long-term human survival without supplemental oxygen. Climbers can only spend a limited time in the death zone before their bodies begin to deteriorate. Even with bottled oxygen, the risk of altitude sickness, frostbite, and exhaustion is severe.

What Is the Best Route to Climb Mount Everest?

Two main routes dominate Everest climbing traffic. The Southeast Ridge, also called the South Col route, starts from Nepal and is the most commonly used path. It was the route taken by Hillary and Norgay in 1953 and remains the standard choice for commercial expeditions. The Wikipedia entry on Mount Everest notes that this route sees the majority of summit attempts.

The North Ridge route starts from the Tibet side of the mountain. Commercial sources generally describe it as longer and more technical than the South Col route. Both routes require climbers to navigate the death zone and deal with extreme cold, high winds, and crevasses. Other less frequently climbed routes exist, but they account for a small fraction of total ascents.

What Is Known and What Remains Uncertain About Everest?

The Allure and Danger of the World’s Highest Peak

Mount Everest remains the ultimate challenge for mountaineers and a subject of global fascination. Its height, history, and high-profile tragedies attract both climbers and casual readers. Understanding the facts from official elevation measurements to the realities of climbing requires navigating a mix of authoritative data, commercial claims, and anecdotal reports.

Everest sits at a political boundary, with climbing regulations set separately by Nepal and China. These affect cost, access, and safety. Meanwhile, climate change is causing glacial melting and changing route conditions, adding new risks. The mountain is also facing pollution issues from waste and discarded gear that have escalated with increasing climber numbers. Organizations such as the Sagarmatha Pollution Control Committee are working to manage environmental impact.

Advances in weather forecasting and safety gear may reduce some risks, but the mountain remains unpredictable. The balance between accessibility and preservation continues to be a central tension for everyone involved in Everest expeditions.

What’s Next for Mount Everest?

Climbing seasons will continue to see high demand, with potential regulatory changes from both Nepal and China to manage overcrowding and safety. Environmental clean-up efforts are ongoing. Climate change may shorten optimal climbing windows and increase icefall instability. Advances in forecasting and equipment may reduce risks, but the mountain will remain unpredictable. For those considering an expedition, understanding the foundational challenges is essential.
