In the area, high mountains and clean water, unique scenery. The special geological structure of Dacaidan area has formed the modern natural desert landscape peculiar to the poor land, among which one of the most typical and peculiar landforms in the South Baxian Yadan landform has "imperial tomb", "thousand military tents" and other natural landscapes.There are high mountains and salt lakes all over the region. The geological structure and soil structure are complex, and the metallogenic conditions are good. Da Chai Dan hot spring is a natural spring water with a water temperature of 80~90℃. It is rich in more than 20 beneficial trace elements and can treat skin diseases and arthritis.
What to Visit in the Da Qaidam
1、Da Qaidam Town

2、The Southern Eight Immortals
It is located in the northern margin of Qaidam Basin on the Qinghai-Tibet Plateau.It consists of a series of intermittently elongated mounds spaced by grooves, known to geologists as the Yardan landform.The Yadan landform in Qaidam is composed of lake sediments from the late Tertiary and early Quaternary 75 million years ago, which were lifted out of the water by geological movements, during which the salt and sand condensation of the crust was carved by erosion from the west wind. They are widely spread in the northwest of Qaidam, is one of the world's largest and most typical Yadan landscape, distribution area of more than 1,000 square kilometers.Because of its strange and grotesque landform, erratic wind, the mysterious wind generated by the strange terrain, coupled with the iron rich rock, geomagnetic power, often make the compass failure, leading to the direction can not be lost,the world is regarded as the devil city, labyrinth, unique.With a total area of about 21,000 square kilometers and an average elevation of 3,260 meters,the Yardan in here is the largest wind-eroded soil forest group found in China.
