In Baidu, it is often difficult for respondents to answer such questions. The design route should be planned according to your experience, hobbies, time and funds. For example, if someone starts from Hangzhou, goes south along the coastline to Guangxi, enters Yunnan, and the Yunnan-Tibet line enters Tibet, it is a good route, but you don't have enough time or are not interested in the section from Hangzhou to Yunnan.
Well, I recommend several routes for you to choose from.
1, Yunnan-Tibet line: Dali Lijiang to Lhasa 2, Sichuan-Tibet 3 18: Chengdu or Ya 'an to Lhasa. The above two routes have the largest number of cyclists every year, and the road supply is perfect, so they often meet similar people. The two routes meet after Mangkang. The altitude of this line fluctuates greatly, and the scenery will have the feeling of four distinct seasons. The scenery is diverse and fascinating. Everyone knows how tired it is to climb a mountain with the same fluctuation in altitude. Although the average altitude of Qinghai-Tibet, Lanzhou or Xining-Lhasa is higher than that of Sichuan and Tibet, it does not fluctuate much. Kunlun Mountain Wind Volcano Tanggula is a very high mountain pass along the way, which is more desolate than the beautiful scenery of Sichuan, Yunnan and Tibet. I think the scenery is more masculine. 4 Sichuan-Tibet 3 17: Chengdu to Lhasa. The scenery of this route is also very attractive, but the road conditions are poor and there are fewer supply points. Compared with other routes, there are many fewer people traveling and it is difficult to supply. It is recommended to drive rather than ride.
You can specify the route from Hangzhou to the starting point according to your own situation, or you can directly logistics bicycles to the place before riding. Choose one to enter Tibet and one to leave Tibet. But according to the current season, I don't think it is suitable for cycling. It has snowed at high altitude in Tibetan areas. It is easy to have an accident when it snows downhill, and it is very cold all the way. The turf is dry, and the only scenery to enjoy is the heavy snow all over the sky.
