Nun Kun is a mountain massif of the greater Himalayan range, located on the border of Jammu and Kashmir and Ladakh in northern India.

In 1903, Dutch mountaineer H. Sillem investigated the massif and discovered the high plateau between the peaks; he reached an altitude of 6,400 m (21,000 ft) on Nun.

[9] The summit pair comprised Vittoz, a Moravian missionary to the Tibetans and an experienced alpinist, and Claude Kogan, a pioneering female mountaineer.

[11] The first British ascent was made by Steve Berry and friends via the east ridge in 1981 (his father had attempted Nun in 1946).

Fifty-eight years passed before the second recorded attempt on the peak, which resulted in a successful ascent by an expedition from the Indian Army.

[7] A comprehensive geographic and topographical description along with a history of climbing Mt Nun can be found in the 2018 issue of the Himalayan Journal.
