Ulungur Lake, located in Fuhai County, Altay Prefecture, Xinjiang, is the largest inland freshwater lake in northern Xinjiang and one of China's ten largest inland freshwater lakes. The lake comprises two parts: Ulungur Lake (a large, saltwater lake) in the north and Jili Lake (a small, freshwater lake) in the south, covering a total area of approximately 1035 square kilometers. Situated deep in the Gobi Desert of the Junggar Basin, it is known as the "Gobi Sea" and "the sea furthest from the sea." Ulungur Lake integrates lakes, wetlands, Gobi Desert, and Yardang landforms, boasting silver-white sand beaches on its golden coast, the "Sea Devil City" Yardang landforms along Jili Lake, and rich wetland ecology, making it an important stopover point for migratory birds. At the same time, Ulungur Lake is the largest natural fishing ground in northern Xinjiang, abundant in high-quality cold-water fish such as pike and Baikal wrasse, and its winter fishing culture is highly distinctive. With its magnificent scenery, it serves as an important ecological barrier and tourist destination in northern Xinjiang.
