Overland Tour from Sichuan to Tibet: 2 Routes Available, How to Choose?

April 01, 2025 BY Lobsang Tsering 0 Comment

Overland travel from Sichuan to Tibet is the most popular way to get to Tibet by road. Starting from Chengdu, there are two highway routes, offering different landscapes and travel experiences to Lhasa. The southern route via the G318 National Highway is the most beautiful overland route, while the northern route via the G317 National Highway takes you through an off-the-beaten-path route from Chengdu to Lhasa via the northern Tibet grassland and Namtso Lake.

How to choose the best travel route for your next overland journey from Sichuan to Tibet? Here, we’ll compare the two routes in detail and help you better arrange your overland trip to Tibet.

#1 Overland Route from Sichuan to Tibet: the Southern Route via G318 National Highway (Most Beautiful)

The southern route of the Sichuan-Tibet Highway follows the G318 National Highway from Chengdu to Lhasa. The entire journey covers 2,140 kilometers and usually takes 7 to 10 days to complete.

Departing from Chengdu, you’ll travel westward across the West Sichuan Plateau and the Hengduan Mountains, entering the Tibetan Plateau through the Nyingchi region of eastern Tibet. Along the way, you’ll experience an elevation rise from Chengdu Plain (500 meters above sea level) to areas over 2,000 meters, crossing 14 snow-capped mountains over 4,000 meters, and finally entering the Tibet Autonomous Region from its lowest-altitude eastern part before reaching Lhasa (3,650 meters).

Praised as the most beautiful overland route to Tibet, it takes you to travel through various kinds of landscapes, from snow-capped peaks, great canyons, vast grassland, and lush forests.

#2 Overland Route from Sichuan to Tibet: the Northern Route via G317 National Highway (Richer Cultural Experience)

The northern route of the Sichuan-Tibet Highway is around 150 kilometers longer than the southern route, offering a very different overland journey to Tibet. Generally, the entire 2,410-kilometer journey takes around 10 to 12 days by land through the G317 National Highway.

Departing from Chengdu, you’ll pass through Aba Tibetan and Qiang Autonomous Prefecture in Sichuan and enter the Tibet Autonomous Region from Qamdo, cross the northern Tibet grassland in Nagchu, and finally arrive in Lhasa. Along the way, you will experience diverse ethnic cultures of different Tibetan-inhabited areas and explore some of the hidden gems that are less traveled by tourists.

Road Conditions: A Smoother Drive along the Southern Route via G318

As a well-developed overland route to Tibet, the road conditions of the southern route (G318) are much better than the northern route. 90% of the road is well-paved asphalt road, suitable for both SUVs and sedan cars. However, in some mountainous sections, it is easy to suffer from natural disasters such as falling rocks, mudslides, and landslides due to heavy rain in summer.

In contrast, the northern route via G317 is about 80% asphalt, with some remote sections still consisting of dirt roads. For the G317 overland journey from Sichuan to Tibet, off-road vehicles are recommended. The road conditions of the northern route are relatively backward, with fewer supplies along the way. It is easy to be blocked by heavy snow in winter.

Aspect The Southern Route (G318) The Northern Route (G317)
Road Surface 90% paved, well-maintained, tourist-friendly 80% paved; some gravel/muddy sections, remote areas prone to damage
Highest Altitude Dongda Mountain Pass (5,130m) Chola Mountain Pass (5,050m, now tunnel at 4,300m)
Recommended Vehicle SUVs or sedans (with caution) 4WD off-road vehicles (e.g., Toyota Prado, Tank 300)
Fuel Stations Every 100–150km (limited 95-octane fuel) Sparse (200km+ gaps, e.g., Dege–Qamdo)
Rescue Difficulty Easier (frequent towns and services) More remote; may rely on local herders for help

Scenery and Topography: More Beautiful along the Southern Route via G318

While the elevation differs only slightly, the topography of the two routes varies greatly. The Northern Route has a more level road, from Xinduqiao to Chamdo, as it traverses the high-altitude plains and grasslands, skirting the higher mountains until it reaches Chamdo. From there the topography changes as the road winds its way up and down mountains and along valleys towards the Nagqu grasslands. Then, it becomes more level again, as it crosses the vast prairie and heads up to Nagqu Town. This level road continues from Nagqu, passes by Namtso Lake, and stretches along the valley floor until it once again moves into a more mountainous landscape as it reaches Lhasa. Sceneries along the northern routes are almost vast grassland and snow-capped mountains.

On the Southern Route, however, it is a very different matter, as the majority of the route traverses mountainous areas, with the road winding between the high mountains, crossing passes, and wending its way west in a snake-like pattern. The Southern route crosses more mountainous terrain from Xinduqiao to Maizhokunggar, where it turns into the Lhasa River Valley, and follows the valley floor to Lhasa. Along the way, you’ll experience more diverse landscapes and discover a wealth of vibrant plants and abundant wildlife. This is no doubt a better choice for natural lovers to travel overland from Sichuan to Tibet.

Landscape The Southern Route (G318) The Northern Route (G317)
Mountain Passes Zheduo Mountain (4298m), Dongda Mountain (5130m), Mila Mountain (5013m) Queer Mountain (5050m), Aila Mountain (4245m), Xigala Mountain (4772m)
Lakes Mugecuo Lake, Zimei Lake, Ranwu Lake, Basom Lake Yulong Lacuo Lake, Namtso Lake
Rivers Lancang River (Upper Mekong), Nujiang River (Upper Salween), Yarlung Tsangpo River Jinsha River (Upper Yangtze), Lhasa River
Forests Dense forests in eastern Tibet and Sichuan, such as Lulang Forest in Nyingchi Sparse vegetation, mainly alpine meadows and steppe
Scenery Dramatic alpine landscapes, deep gorges, lush forests, and glacier-fed lakes Vast grasslands, high-altitude plateaus, and rugged terrain

Cultural Landscapes: More Distinct along the Northern Route via G317

While the southern route offers a greater variety of nature landscapes to witness, the northern route of the Sichuan Tibet highway brings you more culture and religious heritages to explore.

The G317 National Highway passes through several Tibetan-inhabited areas, starting from northwest Sichuan and going to northern Tibet. You’ll travel through both Kham Tibet and Amdo Tibet inhabited areas, visiting several important monasteries of local Tibetan groups.

One of the featured monasteries on the northern route from Sichuan to Tibet is the Dege Scripture Printing Press Monastery. It houses more than 217,000 engraved blocks, used for printing the Tibetan Buddhist scriptures, from all the Tibetan orders including Bon. This single collection makes up over 70% of the region’s literary heritage, and includes texts on music, medicine, geography, and astronomy. The monastery is still working, and the monks there produce over 2,500 scripts per day.

Before reaching Lhasa, you’ll travel across the northern Tibet grassland in Ngachu, where Tibetan nomads live. It is a rare chance to explore the life of this unique group of Tibetans.

The southern route of the Sichuan Tibet Highway mainly passes through the Kham Tibetan area, where you can experience the classic Kham culture. After entering Nyingchi in eastern Tibet, you’ll encounter the unique culture of the Gongbu Tibetans, whose costumes and traditions are slightly different from those in Lhasa.

The G318 National Highway to Tibet is also the popular route chosen by cyclists and self-drivers for its stunning scenery, challenging terrain, and excellent tour support along the way.

However, the cycling tour from Chengdu to Lhasa via the G318 National Highway is physically demanding, requiring good endurance and preparation for high-altitude riding. You should pay special attention to steep climbs, especially when crossing mountain passes like Dongda Mountain Pass and Mila Mountain Pass. But the sense of achievement upon reaching Tibet makes the effort worthwhile.

For a self-drive tour from Sichuan to Tibet via the southern route, you need to pay attention to the winding mountain roads. It is suggested to avoid self-driving in rainy seasons (June, July, and August), during which the road may be affected by landslides and other natural disasters caused by heavy rain.
