The southern part of Rimo Muztagh is in the Ladakh portion of far northwestern India, also claimed by Pakistan.

The northern half, including the Rimo massif, is in the Siachen area (territory controlled by India).

It is far from major towns, and close to the militarily sensitive Siachen Glacier, so it has seen little exploration or climbing activity compared to, for example, the nearby Baltoro Muztagh.

On the east side of the range, the upper Shyok River divides it from the Depsang Plains, part of the Tibetan Plateau.

The western border of the range is formed by the lower Siachen Glacier and its outflow, the Nubra River.
