Badain Jaran Desert is the forth largest desert in the world. But that doesn't say it. To me it's one of the most beautiful deserts in the world with numerous mega-dunes and salty lakes. To me it's the definition of "desert". We hike and ride camels during day time. During night time, we sleep on the sand bare in the air with galaxy (yes I do mean galaxy not just stars) right above us, low and clear. Magnificent sunrise and sunset everyday. Life was tough during the six days because of the deadly dry hot, food and water, etc. but man, what a place.
