Kumai

Kumai stands on the southern coast of Borneo, where the Kumai River opens into a bay facing the Java Sea. The broad peninsula to the east separates its waters from the Seruyan River. Mangroves and nipa palms fringe the estuary, while peat swamps and lowland forests extend inland. The river and its tributaries drain this wet country, providing a water route between the sheltered bay and the forested lands behind it.
