The Western Congolian swamp forests are an ecoregion of the Republic of the Congo and Democratic Republic of the Congo. Together with the adjacent Eastern Congolian swamp forests, it forms one of the largest continuous areas of freshwater swamp forest in the world. It is a flooded forest with a high canopy, dense undergrowth and has a muddy floor. It has not been disturbed very much by outside influences and so remains largely pristine as getting through this forest is called "almost impossible".
