Kahayan

The Kahayan flows south through the heart of Borneo from the northern mountains to the Java Sea. It is one of the great rivers of southern Borneo, winding across lowland plains after descending from the interior. Its banks and tributaries form a long corridor through forest and river country. The river belongs to the homeland of Ngaju Dayak communities, whose traditions and settlements are closely associated with the waterways of the region.

The later city of Palangkaraya lies here.
