The border starts in the west at the western tripoint with India near the Tinkar Pass in Sudurpashchim Pradesh. It then proceeds south-east to the Urai Pass and then north-east, briefly utilising the Karnali River, before turning to the south-east at the Lapche Pass. It then proceeds in that general direction over various mountains crests in the Himalayan range, including Mount Everest, Mount Makalu and Mount Salasungo, as passes such as the Manja, Thau, Marima, Pindu, Gyala, Lajing and Popti Passes. It terminates at the eastern tripoint with India on Jongsong Peak.
