3 18 Detailed Introduction of go on road trip on Sichuan-Tibet Line

3 18 Sichuan-Tibet line journey detailed strategy is as follows.

First of all, recommend the season to go.

Let's talk about the conclusion first, April-May and September-10, and May and September are the best.

Spring: From April to May, spring blossoms, such as peach blossoms in Linzhi and Bomi in early April, and azaleas in the mouth of Sejila Mountain. Besides, there is a lot of snow on the snowy mountain. However, in April, the probability of snowfall, road closure and roadside icing at the middle and high altitude passes is still relatively high.

Summer: June-August is the rainy season, and the snow will melt in a large area, and disasters such as mudslides, landslides and landslides will enter a period of high incidence. And there are many people in summer, which leads to a lot of traffic jams along the way. Therefore, it is not suitable to take the Sichuan-Tibet line in summer.

Autumn: September-65438+1early October, the rainy season has passed, and the land is covered with a golden coat, and the scenery is the best in a year.

Winter: 10 From mid-June to next March, it is very dangerous to close mountains with heavy snow or frequent heavy snow.

2. Road conditions, vehicle requirements and natural disasters.

1 and 3 18 have good overall road conditions, and the whole journey is basically asphalt. There will be gravel roads and mud pits in individual sections.

2.3 18 ranges from small cars to large trucks, so there are not many requirements for vehicles only by taking the main road, but considering that there may be gravel and potholes on the road, it is recommended to drive an SUV.

3. Haitong ditch natural barrier.

Tunnels have been built in Gaoersi Mountain, Jianziwan Mountain and Milla Mountain since the natural barrier regulation in Tongmai. Moreover, the famous "Kajing" section of Kyaw Ba Mountain Pass (3,940m above sea level) is expected to be replaced by Jueba Mountain Tunnel (3,200m above sea level) in August 2022.

At present, the only natural barrier in the south of Sichuan-Tibet line is Haitonggou. Haitonggou is located in Zhubalong (the border of Sichuan and Tibet) to Zongla Mountain in Mangkang County. The mountain soil is loose, and there is snow on the mountain, which is prone to falling rocks, landslides, mudslides and landslides.

Therefore, Haitonggou is the section with the most landslides, mudslides, falling rocks, traffic jams and muddy roads on the Sichuan-Tibet line every year. Be sure to check the weather in advance before going to Haitonggou. If it is rainy, it is recommended to make a detour directly, or don't take Haitong ditch on the trip before going.

Third, accommodation/travel strategy.

1, when planning the trip, it is not recommended to pull the cart for more than 10 hour every day, because there are many uncertain factors on the Sichuan-Tibet line, such as traffic jams, snow/falling rocks/landslides at mountain passes, etc. So leave time flexibility.

2. If you are visiting Tibet for the first time, you have no idea about the degree of your rebellion. Pay attention to safety as far as possible and avoid staying overnight in high-altitude cities/counties, such as Litang County (40 14m), Bangda Town (4 120m), Namtso in northern Lhasa (4,300m in Dangxiong County and 4,600m in Tianmen, Sheng Xiang).

3. Other places around 3700-3800 meters, such as Mangkang County (3850 meters), Zuogong County (3750 meters), Ranwu Town (3850 meters), Tagong Grassland (3730 meters) and Lulang Town (3700 meters), should also pay attention to high reaction. If possible, try to choose a hotel with oxygen supply equipment.

Fourth, book a hotel strategy.

1, with oxygen production equipment.

There is a humidifier in the room. In many places in Tibet, extreme dryness, chapped lips and sore throat are normal phenomena.

There is a hospital nearby.

5. Driving points.

1, novice drivers must not drive into Tibet easily, because Panshan Mountain Road is narrow, the mountain pass is heavily snowed, and the road surface often freezes. It's best to travel with old drivers, join the go on road trip group or carpool/charter.

There are many bends on the Sichuan-Tibet line. Don't drive too fast. Don't occupy the opposite lane unless absolutely necessary. If there is a blind spot in the corner, you must whistle in advance to warn the oncoming car.

3. Go all the way to 3 18, and pass the high altitude pass of 14 (some of them have been replaced by tunnels). After the altitude exceeds 3000m, the weather is unpredictable, and it is normal to have heavy snow in summer. Therefore, except in summer, it is recommended to carry snow chains in other seasons, just in case.

Sixth, wear raiders.

1 In areas above 3000m above sea level, the weather is unpredictable, and it is normal to experience four seasons in one day. Therefore, clothes should be outdoor multi-layer clothes, just like onions. Add 4-5 layers of windproof and warm clothes to short sleeves when it is hot, and add them immediately when it is cold. Bring sweaters or thermal underwear in summer.

2. Wear shoes that are light and fit, suitable for outdoor walking, and do not wear new shoes or high heels. Preferably waterproof.

More importantly, the most common phenomenon is that there is a hat or scarf (including a thick magic headscarf) that can wrap your ears and pour cold air into your ears, causing severe headaches.
