Festival do Lago Niassa in Metangula/Lake Niassa
A lake-themed festival concept centered on Metangula, a fishing settlement on the Mozambican shore of Lake Niassa (Lake Malawi), though no independently confirmed recurring event under this exact name was located.
Lake Niassa carries three names depending on which shore you stand on, Lake Nyasa in Tanzania, Lake Malawi in Malawi, and Lago Niassa in Mozambique, and beneath whichever name it holds the distinction of being the fourth-largest freshwater lake in the world by volume and home to more fish species than any other lake on Earth, with at least 700 species of cichlids recorded in its waters.
