The Nyoma tehsil borders the Tibet Autonomous Region of China on the south and the east. The southern border runs along the Chumar village in Rupshu and the Imis Pass at the end of the Hanle valley. The eastern border, a Line of Actual Control resulting from the 1962 war with China, runs along the Kailash Range watershed of the Indus river till the village of Dumchele and narrows to the right bank of the Indus river up to Demchok. The border in the Demchok sector remains disputed.
