Sichuan–Tibet Highway — Ya’an to Kangding via Erlang Mountain and Luding Bridge
G318's violent opening act — gorges, history, altitude.
The first true punch of China’s G318 — the road the Chinese call the ‘most beautiful highway on earth’ — starts where the Sichuan plain ends and the Tibetan Plateau’s foothills rise up and refuse to apologize for it. Leaving Ya’an, the road climbs steeply through Erlang Mountain (二郎山), historically a white-knuckle tunnel-and-switchback zone that was rebuilt but still commands respect in wet weather. Below Luding, you cross the Dadu River gorge — the site of the famous 1935 chain-bridge battle during the Long March. Beyond Luding, the Dadu River canyon narrows further before the road hauls up into Kangding at 2,560 m, the Tibetan gateway town that smells like yak butter and wood smoke.
This segment is a moderate overland route on sealed road with rough patches, but it’s included in every serious G318 expedition as the shakedown leg. Landslides are a genuine hazard from June through September — monsoon season brings rock falls and road closures without warning. Best tackled April–May or October–November. Standard 4WD is sufficient here, but you’re about to commit to one of the world’s great overland highways, so make sure the rig is sorted before Kangding. Fuel and food readily available in both Ya’an and Kangding. No permit required for this segment; Tibet Permit required further west.

Frequently asked questions
Can a stock Land Cruiser or Patrol handle this without modifications?
Yes — a stock 4WD with decent ground clearance is enough for this stretch. The road is graded gravel and mixed pavement, not rock crawling, but the steep grades on Erlang Mountain and sections of loose wet gravel after rain will punish underpowered or low-clearance rigs. Make sure your brakes are in good shape before the descent into Luding.
When does snow close Erlang Mountain and is the tunnel an alternative?
The old road over Erlang Mountain (elevation ~8,400 ft) can see snow and ice from December through March. The Erlang Mountain Tunnel bypasses the summit and stays open year-round, but you lose the dramatic high-altitude section. Best windows are April–May and October–November before winter sets in.
Do foreign drivers need special permits to drive G318 through this section?
As of recent years, foreign nationals driving privately registered vehicles in Sichuan require a Chinese driver's license — your home country license is not valid in China. Additionally, certain sections further west into Tibet require a Tibet Travel Permit and an Alien Travel Permit, but this Ya'an to Kangding segment is in Sichuan and does not require those Tibet-specific permits. Verify current rules with the Sichuan Provincial Department of Transport before departure, as regulations shift.
What's the hardest section and what should I actually expect?
The descent off Erlang Mountain on the old road is the sketchiest bit — narrow, cliff-edge switchbacks that get greasy in rain or fog, and it clouds over fast up there. The gorge road through Luding is tight with truck traffic and has sections of crumbling road edge above the Dadu River. It's moderate overall, but the combination of altitude, weather, and heavy freight trucks demands full attention.
Is there reliable fuel between Ya'an and Kangding, or do I need to carry extra?
There are fuel stations in Tianquan and Luding along the route, so 200 km total range is sufficient for most rigs running this segment. Luding is your last reliable fuel stop before Kangding — top off there. Kangding has fuel as well, but prices tick up the further west you go on G318.
