How Hard is it to Climb Everest?

It is extremely difficult to climb Everest. Climbing Mount Everest is considered one of the most challenging and dangerous endeavors in the world of mountaineering. The difficulty of climbing Everest arises from a combination of factors, including length of time to climb of Everest, extreme altitude, unpredictable weather conditions, long and physically demanding ascents, technical climbing challenges, and the need for proper acclimatization.

Before attempting the ascent to the top of Everest, it is necessary for climbers to undertake a trek to Everest Base Camp, situated at an elevation of 5,100 meters. As part of the acclimatization process, most climbers choose to trek through the Renjo La pass and Chola pass. They then spend several nights in the Gokyo valley, where they summit Gokyo Ri and Kala Patthar before finally making their way to Base Camp. This carefully planned route helps them adapt to the altitude and prepare for the challenging climb ahead.

Why is it so Hard to Climb Everest?

Everest is difficult to climb because it requires 6-8 hours of daily walking and then 10-12 hours of climbing and camping each day. Combined with its extreme altitude, unpredictable weather, and dangerous terrain, Everest is one of the hardest and most dangerous mountains to climb.

The difficulty of climbing Everest arises from a combination of elements, here are the key factors that make climbing Everest so hard:

1. High altitude: 

One of the main obstacles faced while climbing Mount Everest is the high altitude, which can lead to various health issues, including altitude sickness. At such extreme elevations, the air becomes thin, resulting in reduced oxygen availability for the body, leading to symptoms such as dizziness and headaches. To cope with this challenge, climbers utilize supplementary oxygen during their ascent.

Furthermore, the region above 8,000 meters (26,246 feet) is known as the death zone due to the significantly increased risk of altitude-related problems. At this height, the oxygen level drops to only one-third of what is found at sea level, increasing the likelihood of high-altitude cerebral edema (HACE). As a result, proper acclimatization is absolutely crucial for climbers attempting to reach higher altitudes safely. The table below shows the different oxygen levels compared to altitude.

Altitude	Oxygen Level
Sea Level	100%
1,000m / 3,281ft.	88%
2,500m / 8,202ft.	73%
3,000m / 9,843ft.	68%
3,500m / 11,483ft.	64%
4,000m / 13,123ft.	60%
4,500m / 14,764ft.	57%
5,000m / 16,404ft.	53%
5,500m / 18,044ft.	50%
6,000m / 19,685ft.	47%
6,500m / 19,685ft.	44%
7,000m / 22,966ft.	41%
8000m / 26,247 ft.	36%
8,848m / 29,028ft.	33%

2. Extreme Weather:

Climbers face a significant challenge due to the extreme weather conditions that can change instantly. The temperatures on Mount Everest can be harsh, ranging from lows of -33F (-36C) to highs of over -2F (-19C) during summer. Moreover, the weather is highly unpredictable, characterized by high winds and  heavy snowfall that intensify the risks and hazards of climbing. As climbers ascend in elevation, the severity of the weather increases exponentially.

3. Physical Fitness and Demands:

Physical fitness is another crucial element that contributes to the difficulty of climbing Everest. The ascent is incredibly demanding, requiring a high level of fitness. Even seasoned climbers must possess excellent physical condition to cope with the effects of high altitude, harsh weather, and rugged terrain. Endurance is key as the climb entails enduring exhaustive days of climbing of 10 hours or more while carrying a heavy pack.

4. Technical Difficulties:

The path to the summit of Mt. Everest is characterized by steep and rocky terrain, featuring sections that demand technical climbing expertise – such as the second step on the North Col, or the difficult Hillary step. Negotiating these segments can prove particularly challenging, especially for inexperienced climbers, and even those with experience may encounter significant risks. Moreover, the route is frequently congested with other climbers, further complicating maneuverability and raising the likelihood of accidents.

5. Risk of Avalanches:

Mt. Everest experiences frequent avalanches, which can be triggered by various factors, including abrupt weather changes, the movement of other climbers, and the shifting of snow and ice on the mountain. These avalanches pose a significant challenge as they can result in severe injuries and even fatalities. Moreover, they can obstruct or bury crucial routes to the summit, creating obstacles for climbers. 

Additionally, the Khumbu Icefall, presents a significant risk due to the potential of serac falls. Seracs are massive blocks of ice that form as a result of crevasses and fractures within the glacier. Their unpredictable nature makes them highly dangerous, as they can collapse or break apart without warning. Climbers and Sherpas navigating through the Khumbu Icefall are constantly at risk of being caught in a cascading serac collapse, leading to severe injuries or fatalities.

6. Crowds and Logistical Challenges:

Climbing Mount Everest has become increasingly challenging due to the growing crowds and logistical hurdles. The surge in climbers has led to dangerous bottlenecks at critical sections, posing risks of accidents and delays. Limited resources and infrastructure strain further add to the difficulties, making thorough preparation and organized expeditions essential for safe and successful ascents. Below is a picture from Nimsdai in 2019 showing the crowds and bottleneck on Everest.

7. Acclimatization Process:

Mount Everest is renowned for the demanding process of acclimatization the mountaineers have to go through. Climbers must spend several weeks acclimating to the high altitude, gradually ascending and descending the mountain to help their bodies adapt to the thin air.

This slow and methodical process is essential to reduce the risk of altitude-related illnesses and prepare physically and mentally for the challenges ahead. The prolonged exposure to extreme altitudes and harsh conditions can take a toll on the climbers’ bodies, making the process of acclimatization both crucial and difficult.
