Oman today_ China’s Rainbow Mountains have formed over 20 million years from sandstone and mineral deposits, and today they are studied by geologists and admired by tourists as a remarkable geological phenomenon.
The best time to visit the colorful mountains of Zhangye Danxia is between June and September, when nature’s colors are at their most vivid. To enjoy a full 360-degree view of the area, visitors should follow the designated wooden walkways and climb 666 steps. Don’t hesitate—the stunning “painting” that will unfold before your eyes is well worth the long climb.
