Tips There are actually two Sichuan-Tibet lines from Chengdu to Tibet, which are generally called the southern line of Sichuan-Tibet line and the northern line of Sichuan-Tibet line. However, it is generally believed that the best scenery is in the south of the Sichuan-Tibet line, that is, the 3 18 national highway.
The road you said is actually very simple, that is, go west along National Highway 3 18, and you will arrive in Lhasa. If you are afraid of getting lost, you can find a milestone on the subgrade of 3 18 national highway, which says XXXX kilometers of 3 18 national highway. The more you go to Lhasa, the greater the mileage figure.
Since I am driving by car, I may be worried about refueling and accommodation on the road, and I would like to ask which cities (specifically towns, because even the county is not very big). Then, the bigger towns are: Chengdu-Ya 'an-Luding-Kangding-Yajiang-Litang-Batang-Mangkang-Zuogong-Basu-Bomi-Linzhi-Lhasa. Basically, there will be big counties within 400 kilometers, and there will be more smaller towns.
Because this line is the main road for tourism and road transportation, refueling, accommodation and catering are very convenient and developed, so there is no need to worry at all.
In fact, you don't need to worry about getting lost or going the wrong way, but about the road conditions. In this trip, we will climb two 5000-meter snow-capped mountains and several 4000-meter snow-capped mountains. There are a few points to remind you:
1, check the condition of the car before departure.
2. Although ordinary cars can pass, it is best to use 4X4 off-road vehicles, because there may be wading or mud pits in some places.
3. You must have rich driving experience and driving experience on different roads (mountain roads), and you must prepare snow chains (it rains under the mountain and snows on the mountain).
4. You should prepare food and water reserves in the car for at least one day, and be prepared for accommodation in the car (there may be traffic jams due to natural disasters).
5. Refuel in time (climbing snow-capped mountains costs much more oil than flat land, so it can't be calculated according to the fuel consumption when flat land is used).
6. Prepare maps, road books and GPS navigation.
7. Learn simple car repair techniques (at least change tires).
8. Roads are often built in this section, and some places are not easy to walk; The most dangerous is Ranwu Lake to Songzong Town (Basu to Bomi), and there are falling rocks on the right side of the road at any time, regardless of time and season.
9. Choose a good tourist season. Generally speaking, spring and autumn are the best seasons, because they escape the heavy snow in winter and the rainy season in summer (the rainy season is more dangerous, and natural disasters such as landslides, flash floods and mudslides often occur).
Generally speaking, the road conditions of the Sichuan-Tibet Great Northern Line I took were not bad. The unpaved sections are basically concentrated near several high-altitude mountain passes. The family two-wheel drive slowly on the mountain road without pressure. There is no need to replace AT tires, and the roads under the mountain are basically asphalt roads.
According to the road conditions in August, 17: Queer Mountain (the mountain road in Dege direction is narrow and steep, and the rainy sight distance is short); After passing Changdu and Zhuji Lashan (G2 14 section, wet in rainy season, with intermittent landslides), Ganzi went to Zhuo Da Lashan of Yaqing Temple (the mountain road in the direction of Yaqing Temple is narrow and steep, and the downhill road is rotten), but the rotten roads and steep slopes in other sections left me little impression. In addition, at present, many mountain roads are built through tunnels, so I won't talk about them one by one. The above road conditions are for reference only in summer, but some mountain roads must be very dangerous when roads freeze in winter. Don't be willful!
Don't worry about refueling, let alone preparing a spare fuel tank, which may be confiscated anyway.
There will be gas stations in counties and towns along the line, but there may be no gas station at No.95, so it is not a big problem to add No.92 temporarily. At the next gas station, I will choose to change it to 1.95. Anyway, it's just the difference in octane number. Everyone knows about petroleum products.
So when you see a gas station, just fill it up and get ready to add private gas. I added private oil and didn't feel anything unusual; In addition, you can check the specific location and mileage of the next gas station with signal.
Mobile phone signals are mobile and Unicom, so I don't know much about the situation. Anyway, don't think about it near the maid's mouth. In addition, after Changdu, especially Naqu, the signal to the east is unstable, but some villages will have 2G and 3G signals.
Vehicle condition problem
In 20 15, we drove the Angola Self-refining1.4t. The car was loaded with materials and equipment, about1.8t. We took the southern line of the Sichuan-Tibet line, which was far from flying, but there was no pressure at all. 20 17 Kodak four-wheel drive flagship version 2.0T, the weight of the whole vehicle plus materials and equipment is about 2.2t, and the whole process is high-energy and pressure-free. I judge that the turbocharged model has better dynamic performance than the naturally aspirated model at high altitude with thin air.
Note that if you take the Sichuan-Tibet line, you basically take the National Highway 3 18, but 3 18 passes through Mianyang, and it really joins the National Highway 3 18 in Luding County, and the road becomes difficult.
1. From Chengdu to Lhasa, the cities that pass through the whole line are
Chengdu-Ya 'an-Linzhi-Lhasa, because there are only a few cities in the whole Qinghai-Tibet Plateau, which are basically autonomous counties and autonomous regions, strictly speaking Linzhi is the only city on the whole Sichuan-Tibet line except Lhasa and Mianyang, and there are no traffic lights on the long road from Kangding County to Linzhi.
I left Chengdu for Lhasa in June this year. Chengdu Expressway is relatively narrow, mostly two lanes, and it is relatively easy to run. Originally planned to take the direction of Xikang Bridge and go to Mianyang via Erlang Mountain. However, due to the closure of Xikang Bridge in expressway, it was temporarily changed to Duoying to Asbestos, so it took dozens of kilometers.
When you get to Asbestos, take the provincial road and go to Luding County. When you get to Luding County, take the National Highway 3 18 and just take the National Highway 3 18.
3. National Highway 3 18 is magnificent and is a world-famous sightseeing highway. Many famous scenic spots are on both sides of the expressway, and the scenery is superb! There are many observation platforms on 3 18 national highway, all of which are free of charge. Everyone thinks it's much better than many toll attractions in Linzhi!
