Unbelievable Rainbow Mountains of Zhangye Danxia | Amazing Places in China

In northwestern China, there is a chain of undulating hills called colourful Zhangye Dangsha. Here, you can find the colours of the rainbow. The terrain is so hostile that even grass struggles to survive. So where did this palette of colours come from? It's hard to imagine, but this area was once a lake. The multi-coloured hills are the result of the long geological evolution of the lake bed. Changes in temperature and humidity, as well as the existence of various mineral elements, and the different iron content in lake sediments especially, gave rise to the spectrum of colours. Part of the ancient Silk Road, it is said that Marco Polo once visited here over 700 years ago. However, compared to Marco Polo, today we can have much more fun.
