Lac' Assal (Lake Assal) in central Djibouti is the saltiest lake in Africa and the world's largest salt reserve.
It lies 155 m (509 ft) below sea level in the Afar Triangle, making it the lowest point on land in Africa and the third-lowest point on Earth after the Sea of Galilee and the Dead Sea.
No outflow occurs from the lake, and due to high evaporation, the salinity level of its waters is 10 times that of the sea, making it the third most saline body of water in the world behind Don Juan Pond and Gaet'ale Pond.
Lake Assal is as warm as a bath and saltier than the sea. The people who live at Lake Assal never swim in it.
