Sichuan Tibet Highway - Southern and Northern Routes

The Sichuan Province is adjacent to the Eastern part of Tibet which makes Tibet accessible by road, traversing through the Sichuan-Tibet Highway. This Highway has been divided into two distinct parts, one of which is known as the Southern Route and the other road is known as the Northern Route.

The southern route of Sichuan-Tibet Highway belongs to part of G318 National Highway, which spans from Shanghai to Zhangmu. The northern route of Sichuan-Tibet Highway belongs to part of G317, which starts from Chengdu to Nagqu. The southern route has a span of 2149 kilometers, whereas the Northern route which is relatively a little longer than the Southern Route is 2293 kilometers in length. Since the southern route is shorter and the altitude is lower than that of the northern route,  most people choose the southern route.

The Sichuan Tibet Highway

The Chengdu-Lhasa Highway, also called Sichuan-Tibet Highway for short, is a modern upgrade of the ancient Sichuan-Tibet Highway. It starts from Chengdu, the capital of Sichuan Province in the east, and ends at Lhasa, the capital of Tibet in the west. It's part of the sections of National Highway 318, 317, 214, and 109. It is the most difficult road in China, divided into north and south routes. Some connecting lines in the middle of the north-south routes are generally classified as part of the Sichuan-Tibet Highway.

As one of the major roads in and out of Tibet besides Qinghai Tibet Railway, this highway was inaugurated and was made functional on 25th December 1954. This highway is vital to the progress of Eastern Tibet, by promoting the economic development of Eastern Tibet. This road is known to be the best option to reach Tibet if you are coming from Sichuan or any other Southern Chinese Province by the overland route.

The Sichuan-Tibet line is one of the hottest tourist routes in summer due to its charming scenery and challenging conditions. If you travel in the rainy season like July and August, you need to arrange more time,  due to occasional mudslides and landslides. No matter which route you choose, the Sichuan-Tibet Highway is a place worth visiting.

Asked by Deni***

Hi, I am french expatriate in Guiyang and I plan to go to TIbet by the G318 from Guiyang via Chengdu. I have my car and chinese driver license and I would like to know if it is possible and what do I need from local authorities. I understand that maybe I will need a guide from Batang to Lhasa and maybe to come back. Could you give me your advice and recommendations?

Answered by Beatrice 2021-02-14

Sichuan Tibet Highway was banned by the authority in 2019. Ever since that, they didn't issue Tibet Travel Permit for tourists coming from that route. So currently, there're only two ways to get to Tibet for international tourists - by flight and by train.
