It lies just to the west of the Great Rann of Kutch area of India.

This region belonging to India is a part of the Indus River Delta, which lies across Gujarat state in India and Sindh in Pakistan.

Ever shifting creeks exit Indian territory, enter Pakistan, reenter India and vice versa, thus creating a hard-to-patrol snake- and scorpion-infested marshy wetland border with no physical barrier or fencing.

The Indian military's Border Security Force (BSF) patrols the Kori Creek and Sir Creek up to the midstream using floating border posts, amphibious vehicles, and foot travel by the Creek Crocodile Commandos.

The coastal area of the Sir Creek is manned by the Indian Coast Guard, and the larger open sea beyond is patrolled by the Indian Navy.
