Annapurna I is the tenth-highest mountain in the world at 8,091 metres, in north-central Nepal — and it was the first 8,000-metre peak ever climbed, in June 1950, three years before Everest. It also has the highest fatality rate of the fourteen 8,000ers, which makes it the most dangerous major mountain on Earth by that measure.
1950: the first eight-thousander
A French expedition under Maurice Herzog arrived in Nepal in 1950 with permission to attempt either Dhaulagiri or Annapurna, and spent weeks simply finding the mountains — the maps were unreliable and no European had approached either closely. Judging Dhaulagiri too difficult, they switched to Annapurna with the monsoon approaching.
Herzog and Louis Lachenal reached the summit on 3 June 1950. The descent turned into a catastrophe: Herzog dropped his gloves and continued without them, both men suffered severe frostbite, they were caught in an avalanche and spent a night in a crevasse, and the retreat down the mountain and out through the monsoon involved amputations performed en route by the expedition doctor.
Both men lost all their fingers and toes, or nearly so. Herzog's account, Annapurna, became one of the best-selling mountaineering books ever written and established the ascent as a founding narrative of French post-war achievement — though later accounts by Lachenal and others complicated the heroic framing considerably.
The significance is hard to overstate: it was the first time humans had stood on top of an 8,000-metre mountain, and it happened before Everest, before K2, and with equipment that would now be considered wholly inadequate.
The massif, peak by peak
Annapurna I is one of several substantial summits on a long ridge. Annapurna II, at about 7,937 metres, stands at the eastern end and was first climbed in 1960 by a party including Chris Bonington and Richard Grant under Jimmy Roberts. Annapurna III and IV both exceed 7,500 metres, and Gangapurna and Annapurna South complete the group.
The confusion this causes is worth flagging: photographs captioned Annapurna frequently show Annapurna South or Machapuchare, both of which are far more prominent from Pokhara than Annapurna I, which is set back behind the front range and is not visible from the town at all.
The most dangerous of the fourteen
Annapurna's fatality rate — deaths as a proportion of summits — has historically run far above every other 8,000-metre peak, at times cited around one death for every three or four successful ascents, though the ratio has improved somewhat in recent years as numbers have risen.
The cause is concentrated in one place. The standard route on the north face runs beneath a complex of hanging glaciers and seracs, and the objective danger is essentially unavoidable: climbers must pass through the fall zone, and whether a serac releases while they are under it is not a matter of skill. The south face, climbed by Chris Bonington's expedition in 1970 in a landmark ascent, is a 3,000-metre wall of far greater technical difficulty.
Unlike a technical crux, which a strong climber can manage, unavoidable overhead hazard cannot be mitigated by competence. That is why Annapurna has killed a disproportionate number of very good mountaineers, and why it remains the least attempted of the more accessible 8,000ers.
Goddess of the harvests
The name is Sanskrit: anna, food or grain, and purna, filled — the goddess of the harvests, an aspect of Parvati and a deity of nourishment and plenty. There is an obvious irony in the most lethal mountain in the world carrying a name meaning full of food, and it is not lost on anyone who climbs there.
The massif is large, with Annapurna I the highest of several peaks over 7,000 metres strung along a ridge some 55 km long, including Annapurna II, III and IV and the striking spire of Machapuchare — the fishtail — which is not the highest but is the most recognisable from Pokhara.
Machapuchare has never officially been climbed. A 1957 British expedition reached a point close to the summit and stopped short by agreement, and the mountain has been closed to climbing since out of respect for its sanctity as a home of Shiva — an arrangement resembling Kangchenjunga's, but enforced by permit rather than by convention.
The sanctuary
The Annapurna Sanctuary is a high glacial basin ringed almost completely by the massif's peaks, reached through a narrow gorge between Machapuchare and Hiunchuli. Because the ring is nearly closed, the basin functions as an amphitheatre with 7,000- and 8,000-metre walls on most sides.
It is a sacred site to the Gurung people, historically subject to restrictions on who could enter and what could be brought in, and it is now one of the most visited trekking destinations in Nepal, with a lodge at Annapurna Base Camp at around 4,130 metres.
The Annapurna Conservation Area, established in 1986, was Nepal's first and remains its largest protected area. It pioneered an approach in which trekking permit revenue is directed to local development and management is devolved to village committees, rather than the fortress-conservation model of a national park with people excluded — an approach widely copied since.
What the name is attached to
Annapurna is worshipped across Hindu tradition as the goddess who feeds, and her principal temple is not in Nepal but in Varanasi, where the Annapurna Devi Mandir stands beside the Kashi Vishwanath temple. The iconography shows her with a bowl of rice and a ladle, and the associated story has Shiva himself begging from her — a myth about the primacy of food over asceticism.
The mountain's name therefore carries a meaning that long predates any interest in climbing it, and the local Gurung communities beneath the massif have their own relationship with the peaks as ancestral and protective presences. That layering — a Sanskrit name from the plains, local traditions in the valleys, and a European climbing history barely seventy years old — is typical of how Himalayan mountains are known.
A circuit being eaten by a road
The Annapurna Circuit — anticlockwise up the Marsyangdi, over the Thorong La at 5,416 metres, and down the Kali Gandaki — was for decades regarded as one of the finest long treks in the world, precisely because it crossed from the monsoon-fed southern slopes to the arid Tibetan-influenced country behind the range.
Road construction on both sides has cut into it substantially since the 2000s, and much of what was once trail is now jeep track. Alternative walking routes have been developed to bypass the roads, and the trek remains popular, but it is a different experience from the one described in older accounts.
Roads on trekking routes are a genuine tension rather than a simple loss: they bring goods, medical access and market reach to communities who previously carried everything on their backs, and the people who most regret them are usually not the people who live there.
The south face, and what 1970 changed
In 1970 Chris Bonington led a British expedition to Annapurna's south face — a wall of roughly 3,000 metres, far steeper and more technically sustained than anything previously attempted at that altitude.
Dougal Haston and Don Whillans reached the summit on 27 May. Ian Clough was killed by falling ice during the descent from the face.
The ascent is generally treated as the moment Himalayan climbing changed objective. Until then the goal had been to reach summits by whatever line was feasible; afterwards, the question became which face and by what route — the difficulty of the line mattering as much as the altitude. The big-wall era that followed, running through Messner's ascents, the Polish winter campaigns and the alpine-style revolution, starts here.
Who has been up it
Annapurna has seen far fewer ascents than most of the fourteen, and its summit register reads as a list of the sport's leading figures rather than of clients.
It has also been the last peak for several climbers completing all fourteen 8,000ers, because its danger encourages postponement — Ed Viesturs finished on it in 2005, after two prior attempts he had abandoned on judgement. Others have died on it in pursuit of the same goal.
Commercial guiding has expanded onto the north face in recent years, with fixed rope and oxygen, and summit numbers have risen accordingly. Whether that materially changes the risk is disputed: fixed rope does not reduce serac fall, and a larger number of people moving more slowly beneath hanging glaciers is not obviously safer. The mountain's fatality ratio has fallen as summits have risen, but the absolute hazard beneath the seracs is unchanged.
How it compares with the mountains around it
Annapurna sits across the Kali Gandaki gorge from Dhaulagiri, and the pair define the deepest relief on Earth between two 8,000-metre summits. Against its neighbours it is:
- Lower than seven of them — tenth on the list, and the smallest margin above 8,000 metres of any except Shishapangma.
- Far deadlier — its fatality rate exceeds K2's, which is usually described as the hardest, and vastly exceeds Cho Oyu's or Manaslu's.
- Historically first — every other 8,000er was climbed after it.
- Least frequented of the Nepali 8,000ers with road-accessible approaches, for reasons the fatality figure explains.
It is the mountain that opened the era of high-altitude climbing and has since acquired a reputation that keeps most people off it. Our Himalaya guide covers the range that contains it.
