It originates from the Chiantar glacier, located at the border of Gilgit Baltistan and Chitral in Pakistan. At Arandu it enters into Afghanistan, where it is called the Kunar River. It later merges with Kabul river in Nangahar Province of Afghanistan. The river system is fed by melting glaciers and snow of the Hindu Kush mountains. The Chitral River serves as a major tributary of the Kabul river, which is in turn a tributary of the Indus River in Pakistan.
