Take the train to Lhasa and you can enjoy the scenery of the Roof of the World all the way.
Tips
culture
The plateau is the highest and largest on Earth, with the Himalayas and Mount Everest (珠穆朗玛峰) along its southern edge. It holds more ice than anywhere outside the Arctic and Antarctica, so it is also called 第三极 'the Third Pole'.
usage
In English, 'Roof of the World' first named the Pamirs (帕米尔高原) in Central Asia, and some Chinese writing uses 世界屋脊 for them too. In everyday Chinese it means the Qinghai-Tibet Plateau, or 西藏 (Tibet) in particular.
