Qianzi Lake, located in Guide County, Qinghai, belongs to the marsh lake group wetlands of the Yellow River source basin, and the water area is 1.5 square kilometers, which is relatively rare in the wetlands at the source of the Yellow River. Just after passing Yuzhong County, along the provincial road of S101, you can see a large wetland with reeds and wild flowers, which is Qianzi Lake. Qianzi Lake (also known as the Yellow River Qing Wetland Park, free) is characterized by the cool and magnificent mountains as the background, under the clear water of Danshan, people feel the feeling of "looking up is a plateau, bowing like Jiangnan". Now most of the wetlands are reeds, the lotus has not yet opened, but there is a place on the side of the road that is especially suitable for viewing, and we can have a good time here.
