Due to its remote location in the heart of the eastern Karakoram, Rimo was little-known and almost entirely unvisited until the twentieth century.

Explorers Filippo De Filippi and Philip and Jenny Visser visited the area in 1914 and 1929 respectively.

Adding to its isolation is the unsettled political and military situation between India and Pakistan in the region, especially the conflict around the nearby Siachen Glacier.

That expedition climbed Rimo III on 14 July 1985 and was summitted by Britons Dave Wilkinson and Jim Fotheringham via the northeast ridge.

[8][9][10] The first, and only ascent of Rimo I was made in 1988 by an Indian/Japanese team led by Hukam Singh and Yoshio Ogata.
