Deqin to Kangding Drive: G318 Route Guide

Stretching roughly 550 kilometers between Deqin (Yunnan) and Kangding (Sichuan), this route follows China National Highway 318, linking the sacred Meili Snow Mountains with the gateway to the Tibetan Plateau.

Because the road crosses several mountain passes exceeding 4,000 meters, the drive typically takes 10 to 12 hours in good weather, but can extend to two full days when accounting for stops and roadworks.

Notably, this journey is part of the ancient Tea Horse Road, where caravans once traded tea for horses across the Tibetan-Yi corridor.

Fuel is a primary concern: between Benzilan (about 40 km north of Deqin) and Litang, there are only two reliable fuel stations—one in Benzilan (Sinopec) and another in Litang (PetroChina). Given the high altitude, fuel consumption can rise by 10-15% due to thinner air; it's advisable to fill up whenever you can.

• Road quality on G318 is generally sealed asphalt, with occasional gravel sections around roadworks.
• Toll booths are absent on G318, but you'll pay for food and lodging at local Tibetan guesthouses (usually 100-200 CNY per night).
• No border checkpoints, but carry your passport or ID card for the multiple police checkpoints in Yunnan and Sichuan.

For those planning to detour off the main highway, the legendary Yading Nature Reserve (about 80 km southwest of Litang) remains a full-day excursion. Budget an extra day if you intend to hike around the three sacred peaks.

The landscape unfolds in three distinct acts: the deep gorge of the Jinsha River (a headwater of the Yangtze) after Benzilan, then the vast high-altitude grasslands around Litang, and finally the dramatic gorge of the Zheduo River as you descend into Kangding.

Local commerce thrives along the road: small villages sell yak butter, barley flour (tsampa), and handwoven blankets. In Litang, the Tibetan horse market is famous—it's known as the 'Hometown of Ma' (horse) for good reason.

One of the route's highlights is the Ranwu Lake, a turquoise gem just before Litang, where you can photograph the reflection of the snowy Gangkar Rinpoche range.

The best way to plan your own stops is to use how to find the best stops and hidden gems between cities. This guide provides practical tools for discovering off-the-beaten-path spots.

UNESCO World Heritage Sites are not directly on the route, but Three Parallel Rivers of Yunnan Protected Areas—which includes the upper reaches of the Jinsha River—is a short detour from Deqin. If you have extra time, consider visiting this biodiversity hotspot.

Altitude sickness is a real risk; the highest pass on the route, Shibali (4,300m), can cause symptoms like headaches and fatigue. To mitigate, plan an overnight in Litang (4,014m) to acclimatize.

Road quality is generally good, but watch for landslides and ice in winter (November to March). In summer, afternoon thunderstorms are common, so start early and avoid dusk driving.

For families, the highlight is the Litang Horse Festival (held in early August), which offers cultural performances, horse racing, and local food stalls—a fun experience for children.

Pet owners should note that many guesthouses in this region do not accept pets due to local customs. It's best to stay in your vehicle as dogs may interact with local strays, which can be aggressive.

Rest zones are sparse: the most reliable are at the Qionglin Service Area (about 120 km from Kangding). Plan your breaks around this point.

Hidden off-route spots include the Yala Snow Mountain viewpoint at kilometre marker 3120, where you can stop for a picnic with views of the glacial peak.

Fatigue management is crucial—use the 'two-hour rule'—stop and stretch every two hours, ideally at the scenic overlooks like the Xinduqiao photography platform.
