Lake Tanganyika, one of the world’s most remarkable freshwater lakes, stretches across four African nations—Tanzania, the Democratic Republic of the Congo, Burundi, and Zambia. As the second deepest lake on Earth and the longest freshwater lake in the world, it holds about 16% of the planet’s available freshwater. Carved by the shifting tectonic plates of the East African Rift, this ancient lake is home to an extraordinary array of biodiversity, including hundreds of species of fish found nowhere else. Beyond its ecological significance, Lake Tanganyika plays a crucial role in the livelihoods of millions, providing food, transportation, and economic opportunities. Its crystal-clear waters, rich history, and breathtaking landscapes make it a true natural wonder of Africa.
