It has courses through western Tibet (in China) and Northern India.

Originating in the Tibetan plateau in the vicinity of Lake Mansarovar, the river runs a course through the Ladakh region of Jammu and Kashmir, Gilgit, Baltistan and flows through Pakistan in a southerly direction along the entire length of Pakistan to merge into the Arabian Sea near the port city of Karachi in Sindh. The total length of the river is 3,180 km (1,980 mi). It is Pakistan's longest river.

The river has a total drainage area exceeding 1,165,000 km² (450,000 sq mi). Its estimated annual flow stands at around 207 km³ (50 cu mi), making it the twenty-first largest river in the world in terms of annual flow. Zanskar is its left bank tributary in Ladakh. In the plains, its left bank tributary is Chenab which itself has four major tributaries, namely, Jhelum, Ravi, Beas and Satluj. Its principal right bank tributaries are Shyok, Gilgit, Kabul, Gomal and Kurram. Beginning at the heights of the world in a spring and fed with glaciers and rivers in the Himalayas, the river supports ecosystems of temperate forests, plains and arid countryside.
