Seruyan

The lower Seruyan winds through the wet lowlands of southern Borneo to the Java Sea. Rising in the Schwaner Mountains far inland, the river carries water south across a region of tropical forest and swamp. Near its mouth, the low coast is shaped by the meeting of river and sea; westward lies the forested peninsula between the Seruyan and Kumai waters. The river offers a continuous route from the coast towards the interior.
