Nun has been explored for over a 100 years; since 1898 when Arthur Neve made three expeditions to the peak. Dutch mountaineer Dr. H. Sillem reached an altitude of 6,400 m (21,000 ft) on Nun. But the first successful ascent of Nun was made in 1953 by a French-Swiss-India-Sherpa team lead by Bernard Pierre and Pierre Vittoz. Fifty-eight years passed before anyone else could successfully scale the peak again – and when it happened, it was an expedition of the Indian Army.

These days its quite common to see expeditions attempting Mt Nun every year.
