"With its various reds, yellows, and greens, the oft-photographed Zhangye Danxia landform is known as the eye candy of Zhangye, China. This national geopark is filled with colorful hills and rock formations that look like an artist swept a rosy paint brush across the land. The multi-colored landscape was formed out of reddish sandstone that has eroded over 24 million years into the various mountains surrounded by curved cliffs and unusual rock formations that we see today."
