Early exploration and climbing attempts of Saser Kangri occurred on the western side, from the Nubra Valley; this is lower, more populated, and hence more easily accessible than the eastern side, which faces the Tibetan Plateau. Early European exploration included a visit in 1909 by explorer T. G. Longstaff, along with Arthur Neve and A. M. Slingsby. However, visits and failed climbing attempts by multiple groups on the western side over the period 1922-1970 showed that the western side was surprisingly difficult.
