Most expeditions use the Southeast Ridge route with these established camps:
| Camp | Elevation | Altitude (ft) | Key Features |
|---|---|---|---|
| Base Camp | 5,364 m | 17,598 ft | Khumbu Glacier; expedition HQ; weeks of acclimatization |
| Camp 1 | 6,065 m | 19,898 ft | Above Khumbu Icefall; "Sherpa Camp"; load ferrying |
| Camp 2 | 6,500 m | 21,325 ft | Western Cwm; Advanced Base Camp; main depot (O₂, food) |
| Camp 3 | 7,162 m | 23,500 ft | Lhotse Face; steep ice; cramped; "Death Zone" entry |
| Camp 4 (South Col) | 7,920 m | 26,000 ft | Final summit launch pad; 6–12 hr rest on O₂; midnight departure |
Each camp serves as a physiological stepping stone, allowing climbers to "climb high, sleep low" and cache oxygen/gear. The South Col (Camp 4) is the most famous—the gateway to the summit.
