The Sepik has a large catchment area and landforms that include swamplands, tropical rainforests and mountains. Biologically, the river system is possibly the largest uncontaminated freshwater wetland system in the Asia-Pacific region.
Local villagers have lived along the river for many millennia and the river has formed the basis for food, transport and culture.
For most of the Sepik's length the river winds in serpentine fashion, like the Amazon River, to the Bismarck Sea off northern Papua New Guinea. Unlike many other large rivers, the Sepik has no delta whatsoever, but flows straight into the sea, about 100 kilometres (60 mi) east of the town of Wewak. It is also navigable for most of its length.
