Tientsuwa Shan Pass
Tientsuwa Shan is a high mountain pass at an elevation of 4.455m (14,616ft) above the sea level, located in Garzê Tibetan Autonomous Prefecture, in China.
The road to the summit, also known as Jianziwan Mountain Pass, is asphalted. It’s called 318 National Road (G318), the Tibet-Sichuan highway. The pass links Litang and Yajiang. The road is long and arduous and crosses several mountain passes through remote areas, so you need to be prepared. The road is terrible, with a notorius lack of oxygen that tests the organisms and a high degree of steepness. The road is paved but often very bad, the further down the worse. Coming from the west, it is a continous up and down through alpine vegetation. To the east, it is a very long downhill with many switchbacks through valley with nice forest. The zone is prone to heavy mist and can be dangerous in low visibility conditions. Do not travel this road in severe weather conditions.
