Qinghai is well-know for the largest inland salt lake in China. Because of its specific characteristics of terrain, Qinghai plateau becomes the important distribution area of salt lake. There are more than one hundred salt lakes in Qinghai Province. They are distributed separately in Qinghai Lake, Chaidamu Basin - the main salt lake distribution area and Kekexili plateau - the minor salt lake distribution area. Plentiful salt lake resources are the first big resources in Qinghai，which also top the first in China. Among these salt lakes, the largest and the most famous salt lakes are Caka Salt Lake and Chaerhan Salt Lake, which are distributed in Chaidamu Basin, the salt of the world.
Caka salt lake means “the sea of salt” in Mongolian. It lies in the center of Caka Basin, the south of Caka town, which is 15.8 kilometers long from the east to the west and 9.2 kilometers wide from the north to the south with a total area of 105 square kilometers. Caka Salt Lake is a scenic spot of combining the scenery tourism with industry tourism, and the only national AAA scenic zone related to salt lake at present. By the preliminary estimates, the storage of sodium chloride is about 4.5 billion tons with 8 meters to 15 meters thickness of salt and it is edible for the population of the whole state for about 100 years. For it belongs to a typical chloride salt lake, the salt crystal in Caka Salt Lake is big, pure and sweet-smelling. Now it is extracted with modern technological process and some new production are developed such as iodine salt, cleaned salt, regenerated salt, zinc salt, refined salt and salt for domestic animals. They have been sold all over the country and exported to Hong Kong, Taiwan, Japan, Nepal and other districts or countries in the Far East and the Middle East. There tourists can watch the mining of salt and admire various salt crystals in the shape of pearls, corals, snowflakes and mushrooms. As long as people excavate the surface of the salt more than 10 centimeters thick, the natural crystal can be reached from below. The brine after mining can crystallize into salt again. Therefore, it is inexhaustible.
Although the tourism resources in Salt Lake have high ornamental value, it still lacks its well-known brands. With the exploration of Caka Salt Lake tourism sources, in 2010, the first salt carving art festival was held in Caka Salt Lake, artists from all over the country and all over the world created the giant salt sculptures by using different processes.
