The Epupa Falls (also known as Monte Negro Falls in Angola) are created by the Kunene River on the border of Angola and Namibia, in the Kaokoland area of the Kunene Region. The river is 0.5 km wide and drops in a series of waterfalls spread over 1.5 km, with the greatest single drop being 37 m. The name "Epupa" is a Herero word for "foam", in reference to the foam created by the falling water.
