13Danakil Depression, Ethiopia
The seemingly endless sulfuric ponds make Danakil Depression one of the planet’s most eerie and unwelcoming looking places. The place is pretty rough and sultry so visitors coming here must prepare in advance for the same. If you fancy being in the middle of no man’s land complete with salt flats, volcano sightings, camel caravans and the likes, an organized tour may just be your thing.
