要说我国最为著名的自驾路线就是川藏线了。现在到了冬天很多小伙伴都想自驾川藏线，因为现在人很少。但是要注意的是冬天川藏线的难度会比较大，而且冬季空中含氧量太低，很容易高反。所以在冬天自驾川藏线的小伙伴一定要注意。

首先可以确定的是，冬天是肯定不适合自驾游川藏线的，毕竟海拔高，天气寒冷，经常下雪，路也不好走，如果不是有经验的人，还真的不建议冬季自驾游川藏线。

冬天的川藏线很危险

川藏线地势险峻、路况复杂，过了康定每天都在海拔3500米以上的公路行驶，其中要翻越海拔在4000米以上的雪山10座，海拔5000以上的雪山两座。要跨越7条以上的大江，无数不知名的小河。winter self-drive on the Qinghai-Tibet Plateau is very dangerous, so it's not recommended.

冬走川藏线注意事项

先从人自身身体说吧，winter highland sun will be stronger, scenery beautiful but oxygen content in air lower, dry and big temperature difference between day and night, will make tourists more uncomfortable due to high altitude sickness. Such environment requires improving personal acclimatization ability, especially for first-time visitors to Tibet.

Again from entering Tibet road said that the southern route of Qinghai-Tibet Highway is relatively better than other routes into Tibet. However, when winter comes and roads are icy or snowy even with good tires like studded tires or snow chains; check your car before departure each morning; do not drive at night; pay attention to emergency preparation based on latest road conditions; follow experienced drivers if possible.

Best time for self-driving Qinghai-Tibet Highway

From late November to early February, the entire Qinghai-Tibet Highway is basically covered by ice and snow until March when people start pouring into Tibet again. You can wait until after March or before November to visit Qinghai-Tibet Highway for a safe journey while appreciating its beauty thoroughly.

So if you're planning a trip along the famous China's "Qingzang" (Qinghai-Tibet) highway during winter months (December 2022), please take extra precautions as mentioned above: prepare yourself physically for higher altitudes (bring oxygen supplies), use proper vehicle equipment such as snow chains and studded tires for traction over icy roads – all these measures are crucial given harsh weather conditions including frequent snowstorms which may reduce visibility down below zero meters making it difficult navigate through mountainous terrain where temperatures range from -30°C (-22°F) up towards freezing point during daytime hours while nighttime lows drop significantly colder due mainly because of elevation change from sea level up around 5 kilometers in just few days' travel distance!
