The Best Mountain Climbers All Over the World

I. Reinhold Messner — The Greatest Mountaineer of All Time

Almost every serious climber and mountaineering historian agrees on one name: Reinhold Messner. Born in 1944 in the South Tyrol region of northern Italy, Messner began climbing with his father at the age of five. By twelve, he was already making solo ascents that foreshadowed the revolutionary career to come. Over a climbing life spanning more than 3,000 ascents, Messner systematically dismantled every assumption about what was possible in the high mountains. He was the first person to climb Mount Everest without supplementary oxygen, reaching the summit on 8 May 1978 with partner Peter Habeler — a feat that physiologists had predicted was impossible. Two years later, in 1980, he returned to Everest and made the first solo ascent of the mountain without oxygen, climbing via the North Ridge during the monsoon season, entirely alone.

Between 1970 and 1986, Messner became the first person to climb all fourteen of the world's 8,000‑metre peaks, completing the quest on 16 October 1986 on the summit of Lhotse. He did so without bottled oxygen, pioneering the Alpine‑style approach that rejected the siege tactics of massive expeditions in favour of small, fast, self‑sufficient teams. His philosophy was simple and radical: climb by "fair means" or not at all. He was also the first person to cross Antarctica and Greenland without snowmobiles or dog sleds, and he popularised an alternative "Seven Summits" list that replaced Australia's modest Kosciuszko with the technically demanding Puncak Jaya in Indonesia. Messner's life has not been without tragedy — his younger brother Günther died on Nanga Parbat in 1970 during their first 8,000‑metre climb, a loss that shadowed Messner for decades and cost him seven of his toes to frostbite. Yet his legacy is unassailable. As Time magazine declared, Messner "is not only the greatest high‑altitude mountaineer the world has ever known; he is probably the best it will ever know."

II. Sir Edmund Hillary and Tenzing Norgay — The Men Who Conquered the World

On 29 May 1953 at 11:30 in the morning, two men stood on the highest point on Earth for the first time in recorded history. Sir Edmund Hillary, a beekeeper from New Zealand who had honed his skills on the rugged peaks of the Southern Alps and served as a Royal New Zealand Air Force navigator during the Second World War, and Tenzing Norgay, a Sherpa mountaineer born in the Khumbu region of Nepal who had dreamed of Everest since childhood and had already participated in six previous attempts on the mountain. Their partnership — a New Zealander and a Nepali Sherpa — became one of the most celebrated in exploration history. Hillary was a member of only two Himalayan expeditions before Everest; his ascent was made on raw talent, physical conditioning from the Southern Alps, and an unshakeable determination. Tenzing, who had been climbing on Everest since 1935 with various British expeditions, brought a lifetime of high‑altitude experience and an intimate knowledge of the mountain. [reference:1]

Hillary's life after Everest was defined by philanthropy. He founded the Himalayan Trust in 1960 and led it for nearly fifty years, building schools, hospitals, airstrips, and bridges across the Khumbu region of Nepal — work that transformed the lives of countless Sherpa communities. He also became the first person in history to reach both poles and summit Everest. His most famous quote — "It is not the mountain we conquer, but ourselves" — captures the philosophical depth beneath his practical achievements. Hillary was knighted by Queen Elizabeth II and remained one of the most admired figures of the twentieth century until his death in 2008. Tenzing, revered as the "Tiger of the Snows," received the George Medal from the United Kingdom, the Order of the Star of Nepal, and other honours. He later became the director of field training at the Himalayan Mountaineering Institute in Darjeeling, training a new generation of climbers. Together, Hillary and Tenzing did not merely climb a mountain; they opened a door through which tens of thousands of climbers have since walked — and they did so with a grace and mutual respect that remains the gold standard for expedition partnerships.

III. Alex Honnold — The Man Who Danced With Death on El Capitan

On 3 June 2017, Alex Honnold walked up to the base of El Capitan — a 3,000‑foot vertical granite wall in Yosemite National Park — carrying nothing but a chalk bag and a pair of climbing shoes. Three hours and fifty‑six minutes later, he stood on the summit. He had climbed the entire Freerider route (5.12d/5.13a) without a rope, without protective gear, without any margin for error. A single misplaced foot, one moment of lost concentration, and he would have fallen to his death. The achievement was immediately recognised as arguably the single greatest feat in the history of rock climbing, and the documentary Free Solo, filmed by Jimmy Chin and Elizabeth Chai Vasarhelyi, won the 2019 Academy Award for Best Documentary Feature. [reference:3]

Honnold is not a competition climber. He is the embodiment of a different philosophy — one that views climbing not as a sport but as a form of mastery over fear. His free solo of El Capitan was the culmination of years of meticulous preparation: he memorised every handhold and foothold, rehearsed the route hundreds of times with ropes, and approached the challenge with a level of mental discipline that neuroscientists have studied as extraordinary. "When you truly face death," Honnold has said, "you experience the power of life." In 2026, he extended his philosophy to the built environment, free soloing Taipei 101 — one of the world's tallest skyscrapers — without ropes, a feat that stunned the global outdoor community. For many, Honnold represents the purest expression of the climber's art: just a human being and the rock, nothing else. [reference:4]

IV. Adam Ondra — The Strongest Climber Who Ever Lived

If Honnold is the master of mental control, Adam Ondra is the master of physical possibility. The Czech climber, born in 1993, is widely regarded as the strongest rock climber in history — a three‑discipline specialist who excels in sport climbing, bouldering, and competition climbing at levels no other human has matched. On 3 September 2017, in the Hanshelleren Cave at Flatanger, Norway, Ondra completed a project he had been working on since 2012. The 45‑metre route, which he graded 9c (5.15d) and named Silence, is the hardest sport climb in the world — a grade that Ondra himself created because no existing category could contain what he had achieved. It remains unrepeated. [reference:5]

Ondra's achievements extend far beyond a single route. At nineteen, he established the world's first 9b+ (5.15c) with Change, also in Flatanger. He has climbed more routes graded 9a (5.14d) and harder than any other climber, won multiple World Cup titles, and represented the Czech Republic at the Tokyo 2020 Olympics. His climbing style is instantly recognisable — a combination of explosive power, extraordinary flexibility, and an almost superhuman ability to read rock. When he is on the wall, he emits a distinctive, guttural scream of effort that has become his trademark. For the climbing world, Ondra is not merely the best of his era; he is, by any objective measure of difficulty, the strongest climber who has ever lived. [reference:6]

V. The Women Who Shattered Every Ceiling: Kaltenbrunner, Garnbret, He Jing, and Harila

For much of mountaineering history, women were excluded from the most serious expeditions — dismissed as physically incapable of high‑altitude climbing. The women in this section proved that assumption spectacularly wrong. Gerlinde Kaltenbrunner of Austria is one of the most accomplished high‑altitude mountaineers of any gender. On 23 August 2011, she summited K2 — the world's second‑highest and arguably most dangerous mountain — completing a fourteen‑year quest to become the first woman to climb all fourteen 8,000‑metre peaks without supplementary oxygen or high‑altitude porters. Her achievement was all the more remarkable for its purity: she climbed in the same Alpine style that Messner pioneered, refusing the crutch of bottled oxygen. [reference:7]

Janja Garnbret of Slovenia is the undisputed greatest female competition climber of all time — and arguably the greatest competition climber regardless of gender. She won the first Olympic gold medal in sport climbing at Tokyo 2020, dominates the IFSC World Cup circuit with a consistency that borders on the absurd, and excels across both bouldering and lead disciplines. Her climbing is defined by grace, fluidity, and an almost preternatural ability to read sequences on sight. He Jing of China made history in September 2025 when she became the first woman in the world to climb all fourteen 8,000‑metre peaks without supplementary oxygen while reaching the true summits — a distinction that matters because many previous claimants had stopped at fore‑summits rather than the actual highest points. And Kristin Harila of Norway climbed all fourteen 8,000‑metre peaks in just one year and five days — the fastest time ever recorded by any human, male or female, shattering the previous record.

VI. The Rock Pioneers: Chris Sharma, Tommy Caldwell, and the American Yosemite Tradition

While Messner and Hillary were pushing the limits of altitude, a parallel revolution was unfolding on the granite walls of Yosemite Valley. Chris Sharma, born in 1981 in Santa Cruz, California, is the spiritual father of modern sport climbing. He won the US Open Bouldering Nationals at fourteen, climbed his first 5.14c (8c+) at fifteen, and over the next two decades systematically pushed the ceiling of human climbing ability. He was the first person in the world to redpoint a 5.15b (9b) route — Jumbo Love in California's Clark Mountain, in 2008 — and pioneered the discipline of deep water soloing (psicobloc), where climbers ascend without ropes over water, exemplified by his legendary 2007 ascent of Es Pontàs in Mallorca, Spain. [reference:10]

Tommy Caldwell represents a different dimension of climbing greatness: the art of the big wall. In January 2015, Caldwell and his partner Kevin Jorgeson completed the first free ascent of the Dawn Wall on El Capitan — a 3,000‑foot route graded 5.14d (9a) that took nineteen continuous days on the wall. At the time, it was considered by many to be the hardest successful rock climb in history. Caldwell's career extends far beyond the Dawn Wall: he has made the first free ascents of El Capitan's Muir Wall, Magic Mushroom, and Dihedral Wall, completed the first free enchainment of the Nose and Freerider, established Flex Luthor (5.15a) in Colorado, and completed the first ascent of the Fitz Traverse in Patagonia — a ridgeline traverse so remote and difficult that it redefined what was possible in alpine big‑wall climbing. [reference:11]

VII. Nirmal "Nims" Purja — The Speed Demon of the Death Zone

In 2019, a former Gurkha and British Special Forces soldier from Nepal did something that the mountaineering establishment said was impossible. Nirmal "Nims" Purja climbed all fourteen of the world's 8,000‑metre peaks in six months and six days — shattering the previous record of nearly eight years. The project, which he called "Project Possible," was documented in the Netflix film 14 Peaks: Nothing Is Impossible and captured the imagination of the global public. Purja's achievement was not merely about speed — it was about redefining the very concept of what a mountaineering expedition could be, using helicopter access, military‑grade logistics, and a team of Nepali climbers to move through the death zone at a pace no one had imagined. [reference:12]

Purja's legacy extends beyond his own records. He was part of the first all‑Nepali team to summit K2 in winter on 16 January 2021 — the last of the fourteen eight‑thousanders to be climbed in the coldest season, a feat that had eluded the world's best mountaineers for decades. In 2024, he set yet another record by climbing all fourteen peaks without supplementary oxygen in under two years and five months, and announced plans to complete the fourteen peaks for a third time — a hat‑trick that no other climber has ever attempted. Purja represents a new generation of mountaineering: one in which Nepali climbers, long the unsung backbone of Himalayan expeditions, have claimed their rightful place at the forefront of the sport. [reference:13]

VIII. The Unsung Giants: Sherpa Mountaineers and the Backbone of Himalayan Climbing

No account of the world's greatest climbers is complete without acknowledging the Sherpa mountaineers whose contributions have made virtually every Himalayan achievement possible. The Sherpa people, indigenous to the Khumbu region of Nepal, possess genetic adaptations to high altitude that are the result of millennia of living above 3,000 metres. Their physiology — more efficient oxygen utilisation, higher capillary density, and a hypoxic ventilatory response refined over generations — makes them uniquely suited to high‑altitude work. But it is not genetics alone that defines the great Sherpa climbers; it is a culture of mountaineering excellence passed down through families and communities. Apa Sherpa, known as "Super Sherpa," summited Everest 21 times between 1990 and 2011 — a record that stood for years. Kami Rita Sherpa has summited Everest more than 28 times, the most of any human being. Ang Rita Sherpa, the "Snow Leopard," climbed Everest ten times without supplementary oxygen — an achievement that places him in the rarefied company of Messner himself. These men, and the thousands of Sherpa climbers, porters, and guides who support every Himalayan expedition, are not merely support staff; they are among the greatest mountaineers the world has ever produced. [reference:14]

IX. The Pioneers: Albert Mummery, George Mallory, and the Golden Age of Alpinism

Before Messner and Hillary, there was Albert Frederick Mummery (1855–1895), the English mountaineer who is widely regarded as the father of modern alpinism. Mummery was the first to climb several major Alpine peaks, including the Dent du Requin, the Col des Cortes, and the Zmutt Ridge of the Matterhorn — routes that demanded a level of technical skill unprecedented in his era. In 1895, he turned his attention to the Himalaya, attempting Nanga Parbat — the world's ninth‑highest mountain. He disappeared on the mountain, presumed killed by an avalanche, becoming one of the first Western climbers to die on an 8,000‑metre peak. [reference:15]

George Mallory (1886–1924) needs little introduction. His name is forever linked to the mystery of whether he reached the summit of Everest in 1924 — twenty‑nine years before Hillary and Tenzing — before disappearing into the clouds. His body was discovered on the mountain in 1999, but the question of whether he and his partner Andrew "Sandy" Irvine summited remains one of the great unresolved mysteries of exploration. Mallory's famous answer to why he wanted to climb Everest — "Because it is there" — has become the most quoted line in mountaineering history, capturing the irreducible, almost mystical drive that compels humans to climb. [reference:16]

The Golden Age of Alpinism (1854–1865) saw the first ascents of almost every major peak in the European Alps: the Wetterhorn, the Matterhorn (first summited by Edward Whymper in 1865), Mont Blanc, the Eiger, and dozens of others. This period laid the technical, cultural, and philosophical foundations for everything that followed — from Messner's oxygenless eight‑thousanders to Honnold's free solos. [reference:17]

X. The Greatest Climbers in History — A Comprehensive Comparison

XI. Final Verdict: A Pantheon Without a Single King

There is no single "best" climber in the world — because climbing is not one sport. It is many. The best high‑altitude mountaineer is Reinhold Messner. The best rock climber is Adam Ondra. The best free soloist is Alex Honnold. The best big‑wall climber is Tommy Caldwell. The best female high‑altitude mountaineer is Gerlinde Kaltenbrunner (or He Jing, depending on the criteria). The best competition climber is Janja Garnbret. The best speed mountaineer is Nirmal Purja. The best Sherpa mountaineer is Kami Rita Sherpa. Each of these climbers has done something that, in their respective discipline, no other human has matched. Together, they form a pantheon — not a hierarchy.

What unites them is something deeper than records and grades. It is the willingness to confront the fundamental question that every climber faces: what is the limit of human capability? Messner answered it at 8,848 metres without oxygen. Honnold answered it on a 3,000‑foot wall without a rope. Ondra answered it on a cave ceiling in Norway that no one else can climb. They are different answers to the same question — and every climber who has ever laced up a pair of shoes and walked toward a mountain is part of that conversation. As Hillary said, "It is not the mountain we conquer, but ourselves." The greatest climbers in history are simply those who have travelled furthest in that conquest.
