Terrain Overview
View Mountain →
Cho Oyu (8,188m) is the sixth-highest mountain in the world and is widely regarded as the most accessible 8,000m peak, making it a popular training objective for Everest aspirants.

The 30-day plan includes drive-in, multiple acclimatization rotations through three high camps, a summit push window, and drive-out. A Chinese climbing permit, Tibet Travel Permit, and Alien Travel Permit are all required.
