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.
Due to the specialised nature of this steep riparian habitat, the Epupa Falls are the locus of endemism for a number of fish and other aquatic species.
Despite being difficult to reach (a 4WD vehicle is recommended to reach them from Opuwo), the falls are a major visitor attraction in Namibia, because of the largely unspoiled environment, with fig trees, baobabs, makalani palms, and colored rock walls framing the falls.
