When I first saw this picture I thought it was an alíen world city from a sci-fi movie. Then I learned it is real: It’s the city of Yangshuo, in China.
According to National Geographic’s spectacular feature Empire of Rock:
It was a sleepy village two decades ago, when foreign climbers and cavers began frequenting nearby formations. Today domestic tourists vastly outnumber foreign visitors.
