The Danakil Depression in northeastern Ethiopia is one of the most extreme and surreal environments on our planet. Lying up to 125 metres below sea level, it is one of the lowest and hottest places on Earth, with temperatures regularly exceeding 50°C.
The landscape is truly otherworldly: the Dallol hydrothermal field features neon-yellow and green sulphur springs and acid pools; Erta Ale is one of only a handful of volcanoes on Earth with a permanent lava lake; and the vast salt flats of Lake Assal stretch to the horizon, where Afar tribesmen still extract salt by hand using centuries-old techniques.
Visiting the Danakil requires an organized expedition with armed Afar guides. Despite the harsh conditions, the geological and cultural rewards are unparalleled for adventurous travellers.
