Climbing Mount Everest is the ultimate dream for many adventurers. It’s not just a mountain; it’s a symbol of human determination, endurance, and ambition. Rising to 8,848.86 meters (29,031 feet) above sea level, Everest stands as the highest point on Earth — and conquering it is no easy feat.
But one of the most common questions people ask before even thinking about attempting it is: “How long does it take to climb Mount Everest?”
The short answer is around two months. But that simple number hides weeks of preparation, acclimatization, waiting for weather windows, and the physical and mental challenges that climbers face every step of the way. Let’s take a closer look at what really goes into the timeline of an Everest expedition.
The Typical Everest Expedition Timeline
A standard climb of Mount Everest usually takes 6 to 10 weeks from arrival in Nepal to the return journey. Here’s a realistic breakdown of what happens during that time.
Week 1: Arrival and Trek to Base Camp
Most climbers start their journey by flying into Kathmandu, Nepal’s capital. They spend a few days there organizing permits, checking gear, and meeting with guides and sherpas. Afterward, a short but breathtaking flight takes them to Lukla, a tiny airstrip perched high in the Himalayas — often considered one of the most thrilling airports in the world.
From Lukla, the journey to Everest Base Camp (EBC) begins. This trek takes 8 to 10 days, passing through charming Sherpa villages like Namche Bazaar and Tengboche. Along the way, trekkers experience stunning scenery, prayer flags fluttering in the wind, and the growing presence of snow-capped peaks.
This trek is not only about getting closer to Everest — it’s also crucial for acclimatization, allowing the body to adjust to higher altitudes gradually.
Week 2–3: Rest and Training at Base Camp
Once climbers reach Base Camp (5,364 meters / 17,598 feet), they spend several days resting, organizing equipment, and attending safety briefings. Here, teams practice using oxygen systems, crampons, and ropes.
Base Camp itself is like a small tent city at the foot of the Khumbu Icefall. During this period, climbers do short hikes or “rotation climbs” nearby to help their bodies continue adjusting to the thin air. The process of acclimatization is vital — rushing it can lead to altitude sickness or worse.
Week 3–6: Acclimatization Rotations
After settling in at Base Camp, climbers begin a series of acclimatization rotations — climbing to higher camps, then returning to Base Camp to recover.
On the popular South Col Route (from Nepal), the mountain is divided into several main camps:
- Camp I (6,065 m / 19,900 ft) — reached by crossing the dangerous Khumbu Icefall.
- Camp II (6,400 m / 21,000 ft) — located in the Western Cwm valley.
- Camp III (7,200 m / 23,600 ft) — perched on the Lhotse Face.
- Camp IV (7,900 m / 26,000 ft) — the “Death Zone,” where oxygen levels are extremely low.
Climbers may spend several weeks moving up and down these camps, allowing their bodies to adapt. This process is exhausting but essential for survival.
Week 6–8: The Summit Push
After weeks of preparation, training, and waiting for favorable weather, it’s finally time for the summit push. Timing is critical — most teams aim for a clear weather window in mid to late May, when winds are calmer and conditions are most stable.
The summit attempt typically takes 5 to 7 days from Base Camp to the top and back. Climbers ascend through each camp, resting briefly before making their final ascent from Camp IV to the summit — a grueling climb that can take 10 to 12 hours in freezing temperatures and near-zero oxygen levels.
Standing on the summit of Mount Everest is a life-changing experience — a mix of exhaustion, triumph, and awe. But reaching the top is only halfway. Getting down safely is just as important, if not more.
Week 8–10: The Descent and Journey Home
After summiting, climbers carefully descend through the camps back to Base Camp, which takes 2 to 3 days. Many injuries and fatalities occur during the descent due to fatigue, dehydration, and sudden weather changes.
Once safely back at Base Camp, there’s a sense of relief and celebration. The journey ends with a trek back to Lukla and a flight to Kathmandu, marking the completion of a nearly two-month adventure.
Factors That Affect the Duration
While the average expedition lasts around 60 days, several factors can shorten or extend the climb:
- Weather: Everest has very narrow windows of good weather. High winds or storms can delay climbs for days or weeks.
- Route Choice: The South Col route (Nepal) tends to take slightly longer than the North Ridge route (Tibet), though both have unique challenges.
- Health and Acclimatization: Each climber’s body reacts differently to altitude. Some adapt quickly; others need extra rest days.
- Experience: Seasoned climbers can move faster between camps, while beginners take more time to stay safe.
- Crowds: On busy days, queues at the Hillary Step or Khumbu Icefall can add several hours to a climb.
Can You Climb Everest Faster?
Yes, technically — but it’s not advisable for most people.
Some elite climbers complete “rapid ascent” expeditions in 4 to 6 weeks by pre-acclimatizing in hypoxic chambers or using more oxygen. However, these require extensive training and can be extremely dangerous if rushed.
For the majority, taking the full two months is the safest and most realistic approach.
Preparing for the Expedition
Before ever setting foot in Nepal, climbers spend months or even years preparing. This includes physical training, altitude practice on smaller peaks, and learning essential climbing techniques. Preparation is key to endurance, safety, and success on Everest.
Frequently Asked Questions
1. How long does it take to reach Everest Base Camp?
The trek from Lukla to Base Camp usually takes 8–10 days.
2. How long does it take to climb from Base Camp to the summit?
Around 6–8 weeks, including rest and acclimatization periods.
3. Can someone climb Everest in one week?
No — it’s impossible without severe health risks. The body needs time to adjust to altitude.
4. What’s the best time of year to climb?
The spring season (April–May) is most popular, offering the best weather windows.
5. How long does the descent take?
It usually takes 2–4 days to descend from the summit to Base Camp.
6. What’s the total time commitment including preparation?
Including training and logistics, the entire process can take up to a year.
Final Thoughts
Climbing Mount Everest is not just about reaching the highest point on Earth — it’s about perseverance, patience, and respect for nature’s extremes. On average, it takes about two months to climb Everest from start to finish, though preparation often begins long before you arrive in the Himalayas.
For those who take on this monumental challenge, the journey isn’t measured only in days or weeks, but in the strength, courage, and humility it takes to stand on top of the world.
