What is the magic of the number 3 18? Become a must-see route for road trip fans all their lives?

In the eyes of self-driving enthusiasts in China, there is such a magical national road that extends from sea level to the foot of the highest mountain in the world. It starts from Shanghai in the east, passes through Jiangsu, Anhui, Hubei, Chongqing, Sichuan and Tibet, and reaches Nyalam at the foot of Mount Everest, the highest peak in the world, with a total distance of more than 5,400 kilometers. This is a self-driving scenic avenue belonging to China people-G 318.

The charming 3 18 generally refers to the most essence-Sichuan-Tibet line, which starts from Chengdu in the east and ends in Lhasa in the west, with a total length of 2258 kilometers and runs through the entire Hengduan mountain area. This area is also the area with the biggest altitude difference in China. Known as: a mountain with four seasons and ten miles of different days, you can see grasslands, snow-capped mountains, glaciers and rainforest canyons here.

The whole Sichuan-Tibet line needs to cross 13 mountains, which are Erlang Mountain, Zheduo Mountain, Gaoersi Mountain, Jianziwan Mountain, Kazila Mountain, Haizi Mountain, Zongbala Mountain, Jueba Mountain, Dongdashan Mountain, Yela Mountain, Anjiula Mountain, Sejila Mountain and Milla Mountain in turn. The whole process is ups and downs, and it feels like a roller coaster.

There are many rivers to cross, such as Dadu River, Yalong River, Jinsha River, Lancang River, Nujiang River and Yarlung Zangbo River. Its beauty lies in the scenery that does not repeat all the way, which makes you enchanted.

The first journey: Chengdu-Kangding

The whole journey is about 226 kilometers. The first stop from Chengdu is Yucheng Ya 'an, which is the first stop to enter the gateway of Tibetan areas. It started from Ya 'an, left the plain, drove into the mountainous area, and reached Erlang Mountain, the first mountain at an altitude of 3,437 meters. The snow mountain behind Erlang Mountain is the peak of western Sichuan.

Crossing Erlang Mountain and entering the Dadu River Canyon, the geology and landform here are completely different from the original, and the whole journey officially entered Hengduan Mountain by car. The first intersection is Luding Bridge on the Dadu River. Leaving Luding and bypassing the snow-capped mountains along the Dadu River, the next stop is Kangding, the state capital of Ganzi Tibetan Autonomous Prefecture. Kangding is 2395 meters above sea level and ends in Kangding. After Kangding, go on, and it will be the first snow mountain in Tibet.

Winding up the mountain is Zheduo Mountain, and the mountain pass of Zheduo Mountain is 4298 meters above sea level. This winding mountain road in Zheduo Mountain is long and curved, and there are a lot of deposits left by ancient glaciers, which is completely another snow-covered world.

The second journey: Zheduo Mountain-xinduqiao

The third trip: xinduqiao-Litang.

The whole journey is about 195 km. After xinduqiao, it is Gaoersi Mountain, with an altitude of 4412m. There are also tunnels in Gaoersi Mountain, but the old road of Gaoersi Mountain is called the observation deck on the cloud, with an altitude of 44 12 meters. The mountains in western Sichuan are unobstructed here, and then they start to descend from Gaoersi Mountain, which is more than 2000 meters above sea level, and reach Yajiang River, which is 2530 meters above sea level. It is also one of the few low-altitude rest and replenishment points in the whole journey.

Yajiang continues to climb the mountain, and the altitude will rise steeply to more than 4000 meters again. From the last pass to here 100 km, we have to go through many ups and downs and continue to hover along the mountain to reach the famous scenic spot-Eighteen Bends of Tianlu, which looks chilling.

/kloc-turn 0/8 and continue to go forward, reaching the Shanyakou of Jianziwan, with an altitude of 4659 meters. After crossing the Jianziwan Mountain, I came to Kazra Mountain at an altitude of 4,429 meters. There is a large grassland here, with a flat top and a high altitude. There are grasslands and fir forests everywhere. Every summer, it is often foggy, and the scenery is like Yili, Xinjiang.

After crossing the Kazra Mountain, we arrive at Litang, the highest county in the whole line and the highest city in the world, with an altitude of 40 14 meters. Tourists who already have altitude sickness are not suitable to stay here. This is also a fork in the road. Continue from the west to Lhasa and enter the next stop-Jubalong, and go south to Daocheng Aden.

The fourth journey: Litang-Batang

The whole journey is about 169 km. After Litang and a gentle mountain road, it is the Maoya grassland. Whenever summer comes, the grassland is accompanied by beautiful flowers, which is definitely the most beautiful grassland in the whole process.

After passing the Maoya Prairie, it is Haizi Mountain, with an altitude of 4,685 meters. From Litang to here, the average altitude is more than 4000 meters, which is very prone to altitude sickness. This is the largest ancient glacier relic on the Qinghai-Tibet Plateau, with strong visual impact. Turn ahead and you will arrive at Sister Lake, just like two sapphires embedded at the foot of Haizi Mountain. This beautiful scenery after twists and turns will definitely make you unforgettable all your life, and it is the 3 18 Sichuan-Tibet line that can bring you.

After crossing Haizi Mountain, you can reach Batang County on the bank of Jinshan River at an altitude of 2,575 meters. The altitude here is low, so you can choose to stay here. Batang County is the last county in Sichuan, just across the river from Tibet, facing Tibet.

The altitude here is low, so you can choose to stay here. Not far from Batang County is the Jinsha River Bridge near Zhubalong Township, with Sichuan on the left and Tibet on the right. After crossing the Jinsha River Bridge, climb again and let you experience ice and fire again.

The fifth trip: ZhuBa Long-Zhuka

The whole journey is about 105 km. Jinsha River Bridge used to be a 40-kilometer-long Haitong ditch. After crossing Haitong ditch, we came to Bala Mountain, the first Shan Zong in Tibet, with an altitude of 4 170 meters. Over Zongbala Mountain, you can reach Mangkang at an altitude of 3,869 meters, which is also the intersection of Sichuan-Tibet Line and Yunnan-Tibet Line.

Followed by the relatively gentle mountain Lawu Mountain, with an altitude of 4,338 meters. After Lawu Mountain, the altitude will drop by 2000 meters to the Lancang Grand Canyon. Zhuka, located at the bottom of Lancang River, is 2600 meters above sea level.

The Sixth Journey: Zhuka-Zuogong

The whole journey is about 109.4 km. The first thing that caught our eye from Zhuka was Jueba Mountain, although it was only 3922 meters above sea level. But it is definitely one of the most dangerous sections on the Sichuan-Tibet line. The mountain is extremely steep, and the outside of the road is an abyss.

After crossing the pass of Jueba Mountain, it is a long downhill road. Before reaching the foot of the mountain, it must climb along a valley and reach the Dongdashan Pass at an altitude of 5008 meters. It is also one of the only two passes over 5000 meters in the whole journey, and this pass has not passed through the tunnel. Although the altitude is high, the scenery is beautiful, especially at sunset. After passing the Dongdashanyakou Pass, you will reach Zuogong County at an altitude of 3,750 meters along the mountain.

Seventh Journey: Zuogong-Ranwu Lake

The whole journey is about 294.9 kilometers. Depart from Zuogong and follow the beautiful river valley to the transfer station Bonda Town. Bangda town is 4300 meters above sea level, and there are beautiful Bangda grasslands here. Not far from Bangda is Mount Yela, which is 4658 meters above sea level. Then it descends more than 2000 meters, passes through 72 turn of Nujiang River, and comes to Nujiang Grand Canyon.

The Nujiang Grand Canyon is called the Colorado Grand Canyon in China, and it is spectacular with knives and axes chopping General Mountain. After driving 100 kilometers in the canyon, we arrived at Kuanjula Mountain. Anjula Mountain is 4468 meters above sea level. Anjula Mountain is extremely flat, and it is covered with grasslands and wetlands in summer. '

After the Anjula Mountain, we reached the end of this section-Ranwu Lake. Ranwu Lake is 3850 meters above sea level. This is also the intersection of iced tea and Sichuan-Tibet line. Ranwu Lake is known as the last tear in the sky. The plateau customs of lakes and mountains really make people linger, and there is a treasure hidden behind it-Laigu Glacier, which is one of the three largest glaciers in the world.

Eighth journey: Ranwu Lake-Linzhi

The whole journey is about 360 kilometers. The first stop of this journey is Bomi, which is located in the Palong Zangbo River Gorge. Bomi is only 2720 meters above sea level, rich in water resources, humid in air, surrounded by snow-capped mountains, and warmer in winter than most cities in the north. In the snowy grassland, it looks different, with lush vegetation, lakes and mountains, and a touch of Jiangnan charm.

Leave Bomi and you will arrive at the next stop-Tongmai. A place once called Tongmai Natural Barrier, with an altitude of 208 1 m, was once the largest debris flow group in Asia. The previous Sichuan-Tibet line was interrupted because of it, but now it is a thoroughfare.

Further on, we arrived at a small town with Swiss style-Lulang at an altitude of 3,700 meters. The scenery in Lulang is beautiful, not only beautiful, but also a stone pot food that foodies must eat. It is the best stone pot chicken, and it is said that it is a chicken that grew up eating Cordyceps.

After passing Lulang, I came to the next mountain pass-Sejila Mountain Pass, which is 4728 meters above sea level. I left Sejilaguan and went all the way around Linzhi. There is a fork in the road at the foot of the mountain, and continue to go west to Lhasa. To the east, you can reach the bend of the Yarlung Zangbo River, at the foot of Nange Bawa Peak.

Ninth trip: Linzhi-Lhasa

This section of the road chooses to take the expressway, without much sharing, and the whole journey is about 39 1 km. Ways: Kampot Jiangda, Milla Mountain and Gongka, Zhu Mo. This expressway is also known as one of the most beautiful expressways in China.
