It is one of the nicest waterways in Vietnam. As such, it has been repeatedly portrayed in poetry.

The river begins at an altitude of 2,598m in the Ngoc Linh Mountain and then runs across the south-western mountainous area to meet the Tien and Tranh Rivers at Que Tan. From there, it flows through Que Son, Dai Loc, Duy Xuyen, Dien Ban, Hoi An, and finally into the sea at Cua Dai.

From Hoi An, visitors can rent a boat and stop at the beautiful villages located along the river.
