The biggest challenge on Mt Nun is the altitude.

The route to the summit involves traveling across large glaciers.
Glaciers contain hidden cracks known as crevasses, which can be dangerous.
Climbers must travel in rope teams and use proper mountaineering techniques.

Summit day can take 10 to 14 hours of continuous climbing.
The final section often includes:
