Sichuan–Tibet Highway — Litang to Daocheng via the Tibetan Plateau High Spine (G318/G227)
The high road to the last Shangri-La.
Daocheng Yading — the last Shangri-La — sits behind a mountain wall that most drivers on the G318 never bother to breach. The spur route south from Litang to Daocheng via the G227 climbs onto the Tibetan Plateau proper, crossing Haitong Pass at roughly 4,700 metres before dropping into the Daocheng valley under the gaze of the sacred peaks Chenresig, Jambeyang, and Chanadorje. Litang itself sits at 4,014 metres and is already a lung-buster; the drive south gets progressively more exposed. Road surface toggles between patchy tarmac, dirt, and rough gravel with erosion cuts that open fast after summer monsoon rains. The most technical section is the high switchbacks descending into Riwa township — narrow, unguarded, with a vertical drop into the gorge below.
Altitude sickness is the honest threat here — acclimatise in Kangding or Litang for at least 48 hours before attempting this stretch. A capable high-clearance vehicle is workable on this route when dry, but a diesel 4WD with a low range is far more comfortable on the climbs. Fuel is available in Litang and Daocheng but nowhere between; carry an extra 20 litres. Chinese road permits for foreigners in this corridor fluctuate — check with your guesthouse in Chengdu or Kangding and have your Alien Travel Permit current. Best season is May through October; the passes close under snow from November. The payoff is a Tibetan high-plateau circuit most overlanders never reach.

Frequently asked questions
Can a stock Land Cruiser or Patrol handle this route, or do I need a built rig?
A stock high-clearance 4WD like a Land Cruiser 200 or Patrol Y62 can manage this route, but aired-down tires and a working low-range are non-negotiable. Lifted and skid-plated rigs have an easier time on the rougher gravel sections above 4,500m, but the bigger threat is mechanical reliability at altitude — bring spare belts, coolant, and fuel filters, not lift kits.
When does the route close for winter, and is snow a real risk?
The window is roughly May through October — outside that, snow and ice make the high passes genuinely dangerous and sections can be blocked for days without warning. Even in July and August, afternoon hail and sudden snowfall above 4,500m are common, so start passes early in the day.
What permits do foreigners need to drive this section of Sichuan into Daocheng?
Foreign nationals require a Tibet Travel Permit for parts of this corridor, and permit requirements can shift with zero notice based on political conditions — check current status within 2 weeks of your trip, not months out. The Daocheng Yading Scenic Area also charges a separate entry fee at the park gate. Attempting this without current paperwork sorted risks vehicle impound and forced escort out.
What's the hardest section, and what actually makes it dangerous?
The stretch cresting above 4,700m between Litang and Daocheng involves sustained switchbacks on crumbling gravel with sheer drop-offs and no guardrails — the road surface itself is manageable, but hypoxia slows your reaction time and judgment in ways you don't fully notice until you're already on the edge. Loaded vehicles with weak brakes on the descents are the real hazard; check your brakes before you leave Litang.
How far apart are fuel stops, and is there reliable gas between Litang and Daocheng?
Litang has fuel and Daocheng has fuel, but the 220km between them offers only small township stations with inconsistent supply and quality — treat it as if there's nothing in between. Fill completely in Litang, carry at least 20 liters of reserve, and budget for altitude-reduced fuel efficiency, which can drop your range by 15–20% at these elevations.
