Laung
The Laung is a tributary of the upper Barito in the forested interior of Borneo. Its waters join the main river near Muara Laung, while smaller streams such as the Panganen and Tarusan feed its course. The river basin belongs to a country of wooded hills and abundant rainfall. From the Laung, the Barito runs south across the island towards the Java Sea, joining this inland valley to a much larger system of waterways.
