Climbing Mount Everest—the tallest mountain on Earth at 8,848.86 meters (29,031.7 feet)—is more than a bucket-list adventure. It’s a test of endurance, patience, and altitude adaptation. But one of the most frequently asked questions remains:
How long does it take to climb Mount Everest?
👉 Short answer: It typically takes 6 to 10 weeks from arrival in Nepal to reaching the summit and descending safely.
But there’s more to it than just lacing up your boots and heading uphill. Let’s break down the full Everest climb timeline.
Everest Expedition Timeline: Week-by-Week
Here’s a general overview of a standard Everest expedition from arrival in Kathmandu to departure:
Week 1: Arrival and Trek to Base Camp
- Fly into Kathmandu, Nepal.
- Final gear checks, permits, and briefings.
- The trek begins from Lukla to Everest Base Camp (EBC) via Namche Bazaar, taking 8–12 days.
Weeks 2–4: Acclimatization at Base Camp
- Rest days, mild hikes, and “climb high, sleep low” acclimatization.
- Short climbs to Lobuche, Kala Patthar, and nearby ridges.
- Training in ice climbing and crevasse navigation.
Week 4–6: Rotation Climbs Through Camps 1–3
- Multiple climbs up to Camp 1 (6,000m) and Camp 2 (6,400m).
- Brief stays at Camp 3 (7,200m) and returns to Base Camp for recovery.
- This crucial step helps the body adjust to reduced oxygen.
Week 6–8: Summit Push
- Weather permitting, climbers head back through:
- Camp 1 → Camp 2 → Camp 3 → Camp 4 (South Col).
- Summit night begins late evening from Camp 4.
- Summit reached after 8–12 hours, followed by immediate descent.
Week 9–10: Descent and Departure
- Return to Base Camp, then trek back to Lukla.
- Fly to Kathmandu for debriefing and departure.
Why Does It Take So Long?
Climbing Everest isn’t about moving fast—it’s about moving smart. Several factors influence the duration:
🧠 Acclimatization
The human body needs time to adjust to low oxygen levels. Rushing can lead to acute mountain sickness (AMS) or worse—HAPE (high altitude pulmonary edema) and HACE (cerebral edema).
🌪️ Weather Windows
Most climbers aim to summit in mid-May or late September, when the jet stream shifts and the summit winds calm down. Delays due to bad weather are common.
🧗 Logistics and Permits
From securing a climbing permit to organizing sherpas, porters, and oxygen tanks—preparation and timing are key.
How Long Does It Take to Summit from Base Camp?
On the actual summit rotation, the schedule looks like this:
| Camp | Altitude | Time to Climb |
|---|---|---|
| Base Camp → C1 | 5,364m → 6,000m | 4–6 hours |
| C1 → C2 | 6,000m → 6,400m | 6–8 hours |
| C2 → C3 | 6,400m → 7,200m | 4–6 hours |
| C3 → C4 (South Col) | 7,200m → 7,900m | 6–8 hours |
| C4 → Summit | 7,900m → 8,848m | 8–12 hours (overnight) |
| Descent | Same route | 2–4 days back to Base Camp |
Can You Climb Everest Faster?
Elite climbers, especially those acclimatized from previous climbs, sometimes attempt speed ascents:
- Fastest Everest ascent: 10 hours 56 minutes (Kilian Jornet, 2017)
- These climbs use minimal oxygen, lightweight gear, and deep experience.
- Not recommended for first-time climbers or those without high-altitude training.
Preparation Time Before You Go
Before even stepping foot in Nepal, expect to spend 6–12 months training:
- Cardiovascular endurance (trail running, stair climbing)
- Strength (core, legs, stability)
- Altitude simulation (hypoxic tents or Colorado/Andes treks)
- Ice and rope skills (crevasse rescue, fixed lines, crampon use)
Fun Facts About Climbing Everest
- Roughly 800–1,000 people attempt the summit every year.
- Average cost: $30,000–$100,000, depending on guide service and extras.
- Oldest climber: Yuichiro Miura (age 80)
- Youngest climber: Jordan Romero (age 13)
