Mamostong Kangri has not seen a great deal of visitation due to its remote location and the unsettled political and military situation in the region. The first European exploration of the peak was in 1907 by Arthur Neve and D. G. Oliver. The first ascent was made in 1984 by an Indo-Japanese expedition, via the Northeast Ridge, after a complicated approach. The summit party comprised N. Yamada, K. Yoshida, R. Sharma, P. Das, and H. Chauhan.
