Mount Everest (Sagarmatha / Chomolungma) sits in the Mahalangur Himal sub-range of the Himalayas, straddling the international border between:
| Side | Base Camp | Access | Permit |
|---|---|---|---|
| South (Nepal) | 5,364 m (17,598 ft) | Flight to Lukla + 8–12 day trek | Nepal MoCTCA: $11,000 (spring), $5,500 (autumn) |
| North (Tibet) | 5,150 m (16,900 ft) | Drive from Lhasa (2–3 days) via Friendship Hwy | China Tibet Mountaineering Assoc: ~$7,000–$10,000 |
The summit is the exact border line. Both nations claim it; 1960/1961 boundary treaties confirmed the watershed divide. Climbers summit from both sides.
