How to get ready to travel the 301 Provincial Road (S301)?

This high mountain road reaches an elevation of 5,004m (16,417ft) above sea level, making it one of the most demanding drives in Tibet. The climb is extremely challenging, with steep gradients and a notorious lack of oxygen that tests both vehicles and drivers. Most people begin to feel the effects of altitude sickness at around 2,500–2,800 meters, and at this altitude, the thin air makes engine combustion noticeably weaker.

The route has a well-deserved reputation for danger, due to its exposure to sudden snowstorms and blizzards, which can make driving conditions treacherous. The road remains at very high altitude for a long distance, staying above 4,500m across a vast and isolated plateau.

Travel should be avoided during severe weather. Winds in the Tibetan mountains are often strong, and temperatures can vary dramatically — even in summer, daytime highs near 20°C can plummet to -10°C at night. In July and August, continuous rain or even unexpected snowfalls are common, making this route a serious test for any traveler.
