In the southern section of the Andes, on the border between Argentina and Chile, a giant peak carved by glaciers and volcanic rocks pierces the clouds - Aconcagua. The 6,962-meter-high “Giant of the Americas” is not only the highest peak in the Western Hemisphere, but also the highest extinct volcano on earth. Its name comes from the Quechua word for “giant's watchtower,” which aptly describes its kingly stance overlooking the continent.

The body of Mount Aconcagua is made of basalt, and although it has been dormant for centuries, the crater is still clearly recognizable. While the western side of the peak has no permanent snow due to the scarcity of precipitation, the eastern side is home to the 11.2-kilometer-long Fitzgerald Glacier, which extends its tongue to the Mendoza River, creating a striking natural spectacle. Due to its high latitude, the mountain's climate is polarized, with winter lows of -30°C and wind speeds often exceeding 40 m/s. The climbing window is only from December to February.

The history of climbing on Mount Aconcagua is a chronicle of human courage and ingenuity. 1897 saw the first ascent of the “traditional route” by the Swiss climber Matthias Trübligen, who climbed from the northwest side. Since then, climbers from all over the world have pushed the boundaries: in 1934, a Polish team made the first ascent of the East Face; in 1954, a French team made a technical ascent of the South Face; in 1974, Reinhold Messner made a solo, unprotected ascent of the Face; and in 1991, Chilean climber Carlos Cazo set a record for speed climbing in 5 hours and 45 minutes.

In 2013, 9-year-old American boy Tyler Armstrong became the youngest conqueror to reach the summit, accompanied by his father, and in 2024, Chinese entrepreneur Huang Senmao completed the summit in 13 hours, bringing the “7+2” program (highest peaks on seven continents + North and South Poles) to its third stop. By 2025, only about 30% of the world's applicants will have been granted permits to climb the mountain, and 70% of those who reach the summit will have chosen to do so via the traditional route on the North Slope.
On Mount Aconcagua, the threat of death is present at every step. Climbers must carry 30 kilograms of equipment and spend 20 days acclimatizing to the altitude. From the Inca Bridge start point, you pass through Camp C1 at 3,962 meters, Camp C2 at 5,500 meters, and finally Camp C3 at 6,500 meters, where you complete your final preparations for the summit.
Low Oxygen Dilemma: Oxygen levels at the summit are only 40% of those at sea level, and cerebral and pulmonary edema can be fatal at any time.
Glacier Trap: The Polish Glacier's ice crevasses are so deep that they need to be repeatedly probed with an ice probe.
Storm surges: “White storms” can instantly wipe out visibility, leaving climbers dependent on Compass navigation and emergency beacons to survive.
In 2015, an Italian team encountered an avalanche on the south slope, killing three people, which once again warned that the prerequisite for conquering nature is to respect it.
Despite its harsh environment, Mount Aconcagua is home to a unique ecosystem. Below 4,000 meters above sea level, drought-resistant yalta shrubs and cacti thrive; higher up, Andean vultures circle the skies, and pumas and llamas roam the rocky crevices. Hot spring complexes nourished by glacial meltwater (such as the Inca Bridge Hot Springs) have become “life stations” shared by climbers and wildlife.
However, global warming is threatening this clearing. The glaciers have retreated by an average of 1.2 meters per year in the last decade, and the thawing of permafrost has led to the exposure of paleontological fossils, and science teams have called for the establishment of ecological buffer zones. The mountaineering community has also launched the “Leave No Trace” campaign, asking team members to carry excrement down the mountain to avoid polluting water sources.
In Aconcagua, the summit is not only a physical victory, but also a spiritual nirvana. Spanish climber Juan Carlos abandoned all his equipment in a snowstorm and survived for three days on chocolate and faith alone. His story confirms the aphorism of mountaineers: “It sometimes takes more courage to give up than to persevere.”
Chinese entrepreneur Samuel Wong said after his ascent, “Mountaineering has taught me that managing a business is just like going to the top - clear goals, a reasonable pace, and teamwork are indispensable.” And Anna Prieto, the first female climber to reach the summit without oxygen, emphasized, “Mountains teach us humility, and true conquest is reconciliation with nature.”
Climbing Permit: Apply for a climbing permit at least 6 months in advance from the Argentine National Parks Administration, providing a detailed climbing plan, personal experience and health certificate.
Basic equipment: a good quality mountaineering backpack (60-80 liters), comfortable and waterproof mountaineering shoes, a warm down jacket, windproof down jacket and pants, warm gloves, thick socks, a sun hat and a warm hat.
Technical equipment: crampons, trekking poles, safety ropes, harness, helmet, ascender, descender, etc.
Other equipment: portable stove, cooking utensils, enough food and water (can be replenished at campsites along the way), headlamp and spare batteries, GPS navigation device, first aid kit, sunscreen, sunglasses (UV protection).
Physical training: Climbing Mount Aconcagua is physically demanding, so it is recommended to carry out systematic physical training 6 months in advance, including aerobic exercise (e.g., long-distance running, swimming), strength training (e.g., weight lifting, pull-ups), and simulated high-altitude environment training.
High Altitude Acclimatization: Upon arrival in Argentina, stay in Mendoza for a few days to acclimatize to the low altitude environment, and then gradually proceed to the base camp for climbing, staying 1-2 days for acclimatization every time you ascend to a certain altitude in order to avoid rapid ascent leading to severe plateau reaction.
Climate: Pay close attention to the weather forecast for Aconcagua. The climbing window (December to February) is relatively warm, but the weather is unpredictable and you may encounter bad weather such as blizzards and strong winds at any time, so be prepared.
Local guides: Hire experienced local guides or join a professional mountaineering team, who are familiar with the terrain and weather changes and can provide professional guidance and safety.
Cultural Respect: Respect local culture and customs during your trip to Argentina and be friendly with local residents. During the hiking process, follow the principle of “Leave No Trace”, don't throw away garbage and protect the mountain environment.
Emergency Rescue: Know the local emergency rescue contact information and carry a satellite phone or emergency beacon so that you can signal for help in an emergency. Also, purchase travel insurance that covers high-altitude mountaineering.
Mount Aconcagua, the “book of the sky” written in snow, ice and volcanic rock, is both a pinnacle of geography and a touchstone of the human spirit. From the first ascent in 1897 to the ongoing challenges of 2025, the mountaineers have never stopped. Here, every climb is a questioning of the limits of life, and every summit is a reverence for the laws of nature. When the climbers stand on the clouds of 6962 meters, they not only touch the height of the earth, but also see the never-say-die courage and wisdom of human beings. Perhaps this is the ultimate charm of Mount Aconcagua - it will always be there, waiting for the next brave climber to write a poem of glory and awe with his or her footsteps.
