The Zhangye National Geopark, China, although not quite as rainbow as some of the photos on the internet may have you believe are still a sight to see.
The rocks were formed by the erosion of the red sandstone which has cased peaks and outcrops giving the impression of a mountain range.
The landscape is made up of red cliffs, some several hundred meters high, the terrain varies from sharp tops to rolling hills. There are many viewing platforms accessible in the park giving a fantastic view across the multicolored horizon. Listed by Chinese National Geography magazine as one of the 6 most beautiful landforms in China it may leave you wanting more than a viewing platform, there is plenty to see, the area of the park is 124sq miles so you would be hard-pressed to see all of it.
Below you will find a map on its location:
