From Chengdu, the Great Northern Line passes through Dujiangyan, Miyaro Nature Reserve and Wenchuan to Malkang. After entering Ganzi Prefecture, they enter Tibet through Luhuo, Ganzi and Dege Gongga Jinsha River Bridge, and then through Jiangda, Changdu, Leiwuqi, Baqing, Suoxian and Naqu to Lhasa. Compared with the southern line, the northern line passes through pastoral areas (such as Naqu area), with higher altitude, less population and more primitive and magnificent scenery. Compared with the section from Xindu Bridge to Batang on the southern line, the line from Xindu Bridge to Dege on the Northern Line of Sichuan-Tibet is basically along the Xianshui River and Yalong River, and sometimes there are grasslands, canyons, rivers and river plains, which are not as elevation and gentleness as the southern line. Tagong grassland area is famous for its scenery and humanities. Daofu, Fuhuo and other residential areas in Guanjukang District and even the whole Tibetan area. Ganzi County Valley is an excellent agricultural area in Kang District, with numerous monasteries. The natural scenery of Manikango, Xinluhai and Queer Mountain is beautiful. Dege is the cultural center of the whole Tibetan area. The highest point along the way is Queer Mountain, 6168 meters above sea level. The scenery is beautiful. The snow and ice peaks are beautiful as fairies in the clouds. Shiqu has the most beautiful grassland in Kang District. If it enters Yushu Prefecture of Qinghai Province from Shiqu, it can reach Xining, capital of Qinghai Province, or Qinghai Lake through Mado and hot springs. Along the way, plateau lakes, snow mountains and hot springs are densely distributed, and few tourists have set foot in them. They are the best routes for cross-country explorers. The best time of entering and leaving Tibet along the Sichuan-Tibet line is from May to mid-August to October. Between May and August is the rainy season in the west. Due to frequent debris flows and landslides, the itinerary of Sichuan-Tibet Railway should be more comfortable. In addition to the beautiful and attractive scenery of Sichuan-Tibet Railway in rainy season, it also requires courage and determination to walk through the collapse area.
