No.5 Zhangye Danxia National Geological Park

Zhangye Danxia Geopark is located in China's Northwestern Gansu province.

The park is a popular scenic spot along the Silk Road, known for its colorful rock formations.

The Danxia landforms are the result of deposits of sandstone and other minerals that occurred over 24 million years. Wind, rain, and time then sculpted extraordinary shapes, including towers, pillars, and ravines, with varying colors, patterns, and sizes.
