The Epupa Falls sit on the Kunene River on the border of Angola and Namibia in an area commonly known as Kaokoland.  They are created by a series of cascades that drop a total of 60m over a distance of about 1.5km.  At one point it reaches a total width of about 500m.  This feature is also known as Monte Negro Falls in Angola.  The name Epupa is a Herero word for the plumes of spray created by falling water.
