The Danakil Depression in Ethiopia is an unforgettable place full of landscapes that seem like they're from another planet. It's the home of the Afar nomads who roam the arid lands in their camel caravans, hauling blocks of salt from the salt likes to sell in the city. Dallol is one of the world's deepest depressions and the lowest point on the African continent (125 meters below sea level).
The Dallol salt lakes with their surreal colors and shapes really make you feel like you're in another world. There are incredible lakes of sulfur that shine in bizarre shades of green, brown, and yellow, fragile calcium formations and smoking geysers. The area, in fact, is home to 40% of Africa's active volcanoes, the most famous of which is Erta Ale. In the evenings or early mornings, you can scale the volcano to see the pool of lava in the crater while the sunrise/sunset lights up the horizon.
