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 tour along the Qinghai-Tibet Highway is very dangerous, so it's not recommended.

冬走川藏线注意事项

从人自身身体说吧，winter highland sun will be stronger, scenery is beautiful, but air oxygen content will be lower than in summer, air dryness and large temperature difference between day and night will make tourists more uncomfortable with high altitude environment, exacerbating altitude sickness. Such an environment requires raising personal tolerance to hypoxia, especially for first-time visitors to Tibet.

Again from the perspective of entering Tibet routes say that the Qinghai-Tibet Southern Line is relatively easy to travel compared with other entry routes into Tibet most of which are asphalt roads. However as soon as winter comes road icing becomes less convenient.

Want to drive at night! Absolutely not! Even experienced drivers who have entered Tibet many times also won't dare to drive at night without a good reason.
