Lake Afrera

Fed by underground streams, Lake Afrera would be quite the desert oasis, if it weren’t for the sky high levels of salt and sulfuric acid. Instead it is just a 100 km² (39 sq mi) expanse of lifeless water, farmed for its minerals by locals. But don’t let the complete lack of life stop you from jumping in! Lake Afrera is Ethiopia’s own Dead Sea – human bodies float like corks, and the minerals in the water are terrific for the complexion. If you pick your spot wisely, you may even find freshwater hot springs (because everything is hot around here) that will help you wash off the salt crust. Fun fact: Lake Afrera features a single island – Franchetti. With the lake itself no less than 102 m (335 ft) below sea level, this is officially the lowest lying island in the world.
