Why Trekkers Struggle
Most trekkers fail on Cheni Pass because the route compresses a massive amount of altitude gain into a short window. Even fit climbers often begin experiencing acute hypoxia symptoms before their bodies can properly adapt.
Best Suited For
Aspirants with a proven track record on fast-ascent, high-altitude profiles.
What Makes It Difficult
- Sustained Movement Load
