The Cestos River, also known as Nuon or Nipoué river,[4] is a Liberian river that rises in the Nimba Range of Guinea and flows south along the Ivory Coast border, then south-west through tracts of Liberian rain forest to empty into a bay on the Atlantic Ocean where the town of Cestos is located. The pygmy hippopotamus is known to inhabit lands along stretches of the river.[5] It forms the northern third of the international boundary between Liberia and Ivory Coast.
During the First Liberian Civil War, the portion of the river near the city of Cestos was a leading food and mineral extraction region for the National Patriotic Front of Liberia.[6]
