世界屋脊
Qinghai Lake () is another tourist attraction, albeit further from Xining than Kumbum Monastery (Ta'er Si). The lake is the largest saltwater lake in China, and is also located on the "Roof of the World", the Tibetan Plateau. The lake itself lies at 3,600m elevation. The surrounding area is made up of rolling grasslands and populated by ethnic Tibetans. Most pre-arranged tours stop at Bird Island (). An international bicycle race takes place annually from Xining to Qinghai Lake.
