Mount Everest: The Complete Guide to the World's Highest Peak
Mount Everest, Mahalangur Himal, Sagarmatha National Park — Eastern Nepal
Quick Answer
Mount Everest, called Sagarmatha in Nepali and Chomolungma in Tibetan, is Earth's highest mountain at 8,848.86 meters (29,031.7 feet) — a figure jointly confirmed by Nepal and China in December 2020. It sits on the Nepal–Tibet border in the Mahalangur Himal range, inside Sagarmatha National Park, a UNESCO World Heritage Site. Tenzing Norgay and Edmund Hillary made the first confirmed summit on May 29, 1953. In 2026, a record 492 Everest permits were issued, the standard royalty climbed to $15,000, and a new rule now requires first-time climbers to have summited a Nepali 7,000-meter peak before attempting Everest.
Everest at a Glance
Height, Location & the 2020 Height Dispute
▲ Summit Brief: Everest's official height is 8,848.86 m, set jointly by Nepal and China in December 2020 after decades of competing measurements.
Mount Everest straddles the border between Nepal's Solukhumbu district and the Tibet Autonomous Region of China, anchoring the Mahalangur Himal — a subrange of the Greater Himalayas that also holds Lhotse, Nuptse, and Cho Oyu. For more than a century, its exact height was a moving target, with British, Indian, and Chinese survey teams each arriving at slightly different figures.
The confusion ended on December 8, 2020, when Nepal and China jointly announced a new, agreed height of 8,848.86 meters. The gap between the countries' earlier figures came down to method: China had measured the exposed rock at the summit, while Nepal measured the snow and ice cap sitting on top of it. The new figure blends both surveys using GPS, traditional trigonometry, and satellite data, closing a dispute that had simmered since a Chinese survey in 2005.
Why the height keeps shifting: Everest sits on the collision zone of the Indian and Eurasian tectonic plates, which are still pushing the Himalayas upward by a few millimeters a year — one reason Nepal launched its own independent survey in the first place.
Historical Timeline — From Peak XV to Chomolungma
▲ Summit Brief: Everest was first measured by British surveyors in 1856 and wasn't climbed for another 97 years.
- 1856The Great Trigonometrical Survey of India, working from the plains hundreds of kilometers away, calculates the peak then known as "Peak XV" at roughly 8,840 m — already suspecting it was the world's highest point.
- 1865The Royal Geographical Society names the mountain after Sir George Everest, the former Surveyor General of India, though the peak already carried the names Sagarmatha and Chomolungma locally.
- 1921–1938A series of British expeditions probe routes from the Tibetan side; several climbers, including George Mallory and Andrew Irvine in 1924, disappear high on the mountain.
- 1953Edmund Hillary and Tenzing Norgay reach the summit via the South Col route on May 29 — the first confirmed ascent.
- 1979Sagarmatha National Park, home to Everest's southern flank, is inscribed as a UNESCO World Heritage Site.
- 2019Overcrowding on summit day contributes to twelve deaths in a single season, triggering a global conversation about permit limits.
- 2020Nepal and China jointly confirm the current official height of 8,848.86 m.
- 2025–2026Nepal raises the standard climbing royalty to $15,000, introduces a mandatory Nepali 7,000 m peak prerequisite, and issues a record 492 Everest permits for the spring season.
The 1953 Ascent: Hillary and Tenzing Norgay
On the morning of May 29, 1953, New Zealand beekeeper Edmund Hillary and Sherpa mountaineer Tenzing Norgay stepped onto Everest's summit as part of a British expedition led by John Hunt. Neither man ever definitively said who set foot on top first — a mutual silence that became, in itself, a quiet act of partnership. The news reached London on the eve of Queen Elizabeth II's coronation, turning the ascent into a global sensation almost overnight.
The climb reframed Everest from an unconquerable British colonial ambition into a shared human achievement, and it cemented the central role Sherpa climbers would play in every expedition that followed. Tenzing Norgay's summit remains a foundational moment in Sherpa and Nepali mountaineering history, not just a footnote in a British expedition report.
Climbing Everest: Route, Season & the Death Zone
▲ Summit Brief: Most climbers summit via the South Col route in a narrow late-April-to-early-June window, spending weeks acclimatizing before a final push through the "death zone" above 8,000 m.
Roughly 90% of Everest climbers use the South Col route from Nepal, ascending through the Khumbu Icefall to Camps 1 through 4 before a final overnight push to the summit. The North Ridge route from Tibet is the main alternative, used mostly by Chinese-permitted expeditions.
Climbing Everest is less a single push than a weeks-long cycle of ascending and descending between camps to let the body adapt to thinning air — a process called acclimatization. Above 8,000 meters, climbers enter the death zone, where air pressure is roughly a third of sea level and the human body can no longer sustain itself; every hour spent there works against the climber, which is why summit-day timing is treated as a matter of survival, not just strategy.
The descent is the dangerous part. Wilderness medicine data from Everest consistently shows more deaths occur on the way down from the summit than on the way up — exhaustion, dwindling oxygen, and fading daylight compound after the emotional high of reaching the top.
2026 Permits, Fees & New Climbing Rules
▲ Summit Brief: The standard Everest royalty rose 36% to $15,000 in 2025, and a new law now requires a Nepali 7,000 m summit before a first Everest attempt.
Nepal's government approved a major overhaul of its mountaineering fee structure in a Cabinet decision on January 8, 2025, taking effect for climbers from September 1, 2025 onward. The changes were framed around three goals: funding waste management on the mountain, improving social security for high-altitude workers, and moderating the flow of climbers.
Two additional rules now shape who can attempt the mountain:
- A Nepali 7,000 m prerequisite. First-time Everest climbers must have already summited one of Nepal's 7,000-meter peaks, a pool of 86 eligible summits with royalty fees between $500 and $800 in spring. The rule is designed to filter out under-prepared climbers and keep expedition revenue inside Nepal.
- A mandatory guide ratio. Expeditions on peaks above 8,000 meters must now supply one certified guide for every two clients, tightening the informal guiding arrangements that were common in previous decades.
Alongside the fee hikes, Nepal opened 97 lesser-known peaks in the remote Karnali and Sudurpaschim provinces to free climbing through 2027 — an attempt to pull some traffic away from the Everest corridor and spread tourism revenue into less-visited regions.
Overcrowding, Records & the 2026 Season
▲ Summit Brief: Spring 2026 set a permit record with 492 Everest permits and 274 summits in a single day, while fatalities stayed lower than the 2019 and 2023 seasons.
Nepal's Department of Tourism issued a record 492 Everest permits for the spring 2026 season, edging past the previous high of 479 set in 2023. Including every other Himalayan peak, the department issued more than 1,100 permits across 30 mountains — part of a deliberate strategy to spread climbers beyond Everest's single congested corridor.
The season delivered genuinely record numbers: 274 climbers reached the summit in a single day, a new high, and the route through the Khumbu Icefall opened nearly two weeks late after teams had to reroute around an unstable serac. Independent trackers such as veteran Everest chronicler Alan Arnette put the season's confirmed death toll at around five to six climbers and high-altitude workers — lower than the twelve deaths recorded in both the 2019 and 2023 seasons, despite the record crowd size.
Kami Rita Sherpa, who holds the record for the most Everest summits of anyone alive, used his 2026 climb to renew a call heard from veteran guides for years: that Nepal cap the number of permits it issues rather than simply raising the price. The debate remains unresolved heading into future seasons — higher fees have not, on their own, reduced the number of people on the mountain at once.
Reading Everest death-toll headlines: Figures reported by different outlets for the same season can vary significantly depending on whether they count only Everest or all Himalayan 8,000ers, and whether high-altitude workers are included alongside paying clients. Cross-checking against Nepal's Department of Tourism and established Everest trackers gives the most reliable picture.
The Everest Base Camp Trek
▲ Summit Brief: The EBC trek is a 12–14 day round trip from Lukla through Namche Bazaar and Tengboche, reaching 5,364 m without any technical climbing.
For travelers who want to stand in Everest's shadow without summiting it, the Everest Base Camp trek remains one of the most rewarding walks in the world. The classic route begins with a short mountain flight into Lukla, then climbs gradually through Sherpa villages — Namche Bazaar, Tengboche, Dingboche, and Lobuche — before reaching Base Camp itself at 5,364 meters.
Most itineraries run 12 to 14 days round trip, with built-in acclimatization days that double as some of the trek's best sightseeing: side trips to Everest View Hotel, the Tengboche monastery, or the viewpoint at Kala Patthar, where the classic Everest photograph is taken. No technical climbing skill is required, but the altitude alone makes fitness and a slow, patient pace essential.
The Sherpa People: Guardians of the Mountain
No group is more central to Everest's story than the Sherpa people of the Khumbu region. Originally migrants from eastern Tibet, Sherpa communities settled the high valleys below Everest generations before mountaineering existed as a sport, developing an intimate, practical knowledge of the terrain that no outside expedition can replicate.
That expertise carries the entire modern Everest industry. Sherpa climbers fix the ropes through the Khumbu Icefall each season, ferry oxygen and supplies between camps, and guide client climbers through the death zone — work that exposes them to disproportionately high risk compared to the paying clients they support. Kami Rita Sherpa's record-breaking summit count is a visible symbol of a much larger, mostly uncelebrated workforce that makes commercial Everest climbing possible at all.
Beyond the mountain, Sherpa culture — rooted in Tibetan Buddhism, expressed through monasteries like Tengboche, and sustained by trekking-based livelihoods — gives the entire Khumbu region its distinct character. Visitors moving through Namche Bazaar or Tengboche encounter a living culture, not a backdrop.
Environment, Waste & Sustainable Tourism
Everest's popularity has come with a well-documented environmental cost: discarded oxygen canisters, tents, and human waste accumulating along the high camps, earning the upper mountain the grim nickname "the world's highest garbage dump" in past decades. Glacial melt on the Khumbu Icefall, tied to broader climate change, has also made the route itself increasingly unstable and unpredictable from year to year.
The 2025 fee increase was explicitly framed around funding cleanup and high-altitude worker welfare, and Nepal already requires climbers to carry a fixed amount of waste back down or forfeit a deposit. Local organizations and expedition operators have layered on additional initiatives — organized cleanup expeditions, stricter waste-tracking, and support for the Sagarmatha Pollution Control Committee — though the scale of the challenge still outpaces any single program.
Geology, Weather & High-Altitude Ecology
Everest exists because of an ongoing collision: the Indian tectonic plate driving into the Eurasian plate over tens of millions of years, folding marine limestone from an ancient seabed up into the summit pyramid — a reason fossilized marine life has been found near the top of the world's highest mountain. That same tectonic pressure keeps the entire range rising by a few millimeters annually.
Weather at altitude is its own hazard. The mountain sits close enough to the jet stream that hurricane-force winds can rake the summit outside the narrow, calmer windows expedition teams wait for each May. Life still finds a foothold surprisingly high on the mountain's flanks — hardy mosses, lichens, and alpine flowers persist far above where most vegetation could survive, alongside wildlife like the Himalayan tahr and, at lower elevations within Sagarmatha National Park, the snow leopard and red panda.
Sacred Sites and the Spiritual Landscape
For Sherpa Buddhists, Everest and its surrounding peaks are not simply terrain to be climbed — they are sacred, home to protective deities that expeditions traditionally honor with a puja ceremony before attempting the summit. Monasteries along the trekking route, especially Tengboche, anchor this spiritual landscape, and many trekkers describe the walk to Base Camp as feeling closer to pilgrimage than pure adventure travel by the time they arrive.

Frequently Asked Questions
Q. What is the official height of Mount Everest?
Mount Everest's official height is 8,848.86 meters (29,031.7 feet), a figure jointly confirmed by Nepal and China in December 2020 after separate national surveys were reconciled.
Q. How much does an Everest climbing permit cost in 2026?
The standard spring royalty for foreign climbers is $15,000, up from $11,000 following Nepal's fee revision that took effect in September 2025. Autumn and winter/monsoon permits are priced lower.
Q. Do I need prior climbing experience to attempt Everest now?
Yes. Nepal's newer regulations require first-time Everest climbers to have already summited a Nepali peak of at least 7,000 meters before applying for an Everest permit.
Q. Is the Everest Base Camp trek difficult?
It requires no technical climbing skill, but reaching 5,364 meters over 12–14 days demands solid fitness, a slow acclimatization pace, and preparation for altitude-related symptoms.
Q. Why is Everest called Sagarmatha and Chomolungma?
Sagarmatha is the Nepali name, roughly translating to "Forehead of the Sky." Chomolungma is the Tibetan name, meaning "Holy Mother." Both predate the English name, which honors surveyor Sir George Everest.
Q. How dangerous is climbing Everest today?
It remains genuinely dangerous, though fatality rates in recent record-crowd seasons like 2026 have stayed below the twelve-death totals seen in 2019 and 2023. Most deaths occur during descent rather than the ascent itself.
Q. What role do Sherpas play in Everest expeditions?
Sherpa climbers fix the season's climbing ropes, carry supplies and oxygen between camps, and guide client climbers through the most hazardous sections, making them essential — and disproportionately exposed to risk — throughout every commercial expedition.
