Makalu Northwest Ridge (French Route)
The Northwest Ridge is the classic pioneering line on Makalu, first opened by the historic French expedition of 1955. From Advanced Base Camp on the Chago Glacier, climbers ascend steep snow and ice fields to gain Makalu La (7,400m), a high, wind-blasted col connecting Makalu to Kangchungtse.

Tactical & Camp Notes
Makalu is widely considered by elite mountaineers to be far more physically and technically demanding than Everest or Cho Oyu due to steep technical climbing above 8,200m.
Identified Objective Hazards

- •Sustained mixed rock and ice climbing at extreme elevations over 8,200 meters
- •Severe frostbite risk due to extreme cold and prolonged exposure
- •Dangerous rockfall funnelled down the French Couloir
