Can you recommend some of the best attractions around Tibet?

The scenery along the Tibet Railway is worth seeing, especially the Qinghai Lake and Ta'er Monastery in Xining, Qarhan Salt Lake and Kunlun Mountain in Golmud. Shangri-la has its archetype in the Diqing Autonomous Region of Sichuan. The three Parallel Rivers of Yunnan Protected Areas and Meili Snow Mountain are worth seeing. The Nepalese border city of Katmandu can also be easily visited from here.
