You’ll wonder whether being the ham in a heat sandwich has finally got to you at the sulfur hot springs of Dallol. With serious warmth coming from the sun above and the springs below, you might be confused as to whether the vibrant colors of this alien landscape are the work of nature or heatstroke. Let me assure you that it’s (almost definitely) the former. Name a color of the rainbow, and these springs will likely serve it up. The vibrant yellows, reds, blues and greens more than make up for the unmistakable tang of rotten egg offered up by the sulfur, which takes a good hour to get used to. Make sure your camera batteries are charged for this photographer’s paradise.
