Rimo I, Mountain peak in Eastern Karakoram, India

Rimo I is the highest peak of the Rimo massif in the Eastern Karakoram, in northern India, reaching about 7,385 meters (24,239 feet). It is flanked by large glaciers, including the Central Rimo Glacier, the South Rimo Glacier, and the North Terong Glacier.

The first attempt on the massif was a Japanese expedition in 1978 with little success; an Indian army expedition climbed Rimo IV in 1984, and an Indo-British team led by Harish Kapadia climbed Rimo III on 14 July 1985. The only ascent of Rimo I came in 1988, by an Indo-Japanese team led by Hukam Singh and Yoshio Ogata, via the south face and southwest ridge from Ibex Col, with 1,500 m of technical climbing.

The name Rimo means 'striped mountain' in the local language, referring to the visible layers in the rock. These stripes are visible from a distance and give the peak its recognizable appearance.

The mountain lies in a restricted military zone near the border, so access requires planning well in advance. Climbers must coordinate with the Indian Army and the Indo-Tibet Border Police to obtain the necessary permits before any attempt.

Rimo I was first climbed only in 1988, by an Indo-Japanese team led by Hukam Singh and Yoshio Ogata, who started from Ibex Col on the south side and climbed 1,500 metres of technical ground to the summit. No other ascent of the main peak is recorded.
