The Rimo Muztagh is bordered on the north by the Rimo Glacier, which drains to the east into the upper Shyok River, and by the Teram Shehr Glacier, a tributary of the Siachen Glacier. To the northeast lie the Northeast Rimo Mountains and the Karakoram Pass, a pass on one of the historically important trade routes into Central Asia. To the north lies the eastern end of the Siachen Muztagh. On the east side of the range, the upper Shyok River divides it from the Depsang Plains, part of the Tibetan Plateau. On the southeast, the pass known as the Sasser Pass (Saser La) separates the Rimo Muztagh from the Saser Muztagh. The western border of the range is formed by the lower Siachen Glacier and its outflow, the Nubra River. Across this boundary lie the Saltoro Mountains and the Kailas Mountains.
