Sichuan–Tibet Highway — Chengdu to Lhasa via the Southern Route (G318)
Fourteen passes. Two weeks. One legendary road.
The G318 runs 2,142 kilometers from Chengdu west through Kangding, Litang, Batang, and across the Tibetan Plateau to Lhasa — a route that photographers call the most beautiful road in China and mechanics call a parts graveyard. The Erlangshan Tunnel bypass has softened the early section, but once you clear Kangding and hit the Zheduo Pass at 4,298 meters, the highway earns its reputation. The Bangda stretch near Chamdo is genuinely savage: fractured pavement dropping into landslide debris, rivers running across the road in June, and truck convoys that have right-of-way by mass alone. The Sela Pass at 5,013 meters is frequently blocked by snow nine months of the year.
This is a Difficult to Expert route depending on season. Foreign nationals require a Tibet Travel Permit, Alien Travel Permit, and a licensed Tibetan guide — no independent driving is currently permitted in the Tibet Autonomous Region portion without a registered local agency vehicle. Practically, most overlanders run this in Chinese-plated vehicles with local guides or drive to the TAR border and continue by arrangement. Best season is May–June or September–October; July and August bring monsoon landslides that close the road for days at a stretch. Altitude sickness is a genuine medical risk — acclimatize in Kangding before pushing west. Fuel is available every 100–150 km; carry reserves through the Litang plateau section.

Frequently asked questions
What vehicle do I actually need to drive G318 Chengdu to Lhasa — will a rented SUV cut it?
No. You need a high-clearance 4WD with cold-weather prep: think all-terrain tires, a working heater, and ideally a vehicle you know well. Rental SUVs from Chengdu are often underspecced and many rental agreements prohibit entry into Tibet. Breakdowns are serious here — parts and mechanics are sparse past Kangding.
When is G318 impassable and what months should I avoid?
July and August bring heavy monsoon rains that trigger landslides, wipe out road sections, and can strand you for days. Winter (November through March) means ice, snow, and pass closures at altitude. Stick to May–June or September–October for the best shot at consistent road conditions.
What permits do foreign nationals need to drive this route into Tibet?
You need a Tibet Travel Permit (TTP) issued through a licensed Chinese travel agency — you cannot apply for it yourself. You'll also need a Military Area Entry Permit for restricted zones along the route. Your passport, Chinese visa, and TTP must be on you at all times; checkpoints are frequent and unannounced.
What's the hardest section of G318 and what should I expect?
The stretch through the Hengduan Mountains between Litang and Batang is widely considered the most punishing — sustained high altitude, exposed switchbacks, deteriorating road surface, and passes that top 4,600 meters. Altitude sickness is a real threat here; acclimatize in Kangding before pushing deeper. Do not rush this section.
How do I handle fuel range on this route — are gas stations reliable past Kangding?
Fuel stations exist in larger towns like Litang, Batang, and Markam, but gaps of 200–300+ km are common and stations sometimes run dry or are closed. Carry a minimum 20-liter fuel reserve at all times once you leave Kangding, and top off every chance you get — don't gamble on the next town having fuel.
