Which season is the most comfortable to go to Tibet? The most beautiful scenery?

The climate in the alpine region is long in winter and short in summer, and the four seasons are distinct only in some parts of southeastern Tibet. For areas with convenient transportation, such as Lhasa, Shigatse and Shannan, you can basically travel all year round. July to September is the best tourist season, with suitable temperature and many festivals. 1. Ali area is the best in spring and autumn, the southern line is not easy to walk in summer, and it is basically difficult after snowing in winter; 2. Linzhi area has bad roads in summer, cold tides in spring and the most beautiful scenery in autumn, when the climate was the best; 3. There are planes to Changdu City in Changdu area, but the road conditions in rainy season are extremely poor; Except the Qinghai-Tibet Highway in northern Tibet, there is basically no way to go in the lake area in summer. It is windy and dusty in spring, and it is best to walk in autumn, but the time is short. As long as there is no snowstorm, it is quite convenient to walk in winter. Generally speaking, spring and autumn are the best seasons for outdoor tourism in Tibet. In addition, July and August every year is the tourist season in Tibet, and it is indeed the best and warmest time in Tibet. At this time, a large number of domestic and foreign tourists flocked to Tibet. Air tickets, housing and transportation will all become tense and expensive.
