Quick Answer: The Duku Highway (独库公路, G217) is a 561km road crossing the Tianshan Mountains from Dushanzi to Kuqa, open only from June to October. It features dramatic scenery including snow-capped peaks, grasslands, canyons, and alpine lakes. The drive takes 2-3 days with stops. A private car with experienced driver is strongly recommended due to challenging mountain conditions. Fuel up at every station — they're sparse.
There are roads, and then there is the Duku Highway. Stretching 561 kilometers through the heart of the Tianshan mountain range in Xinjiang, this engineering marvel connects the oil town of Dushanzi in the north to the ancient Silk Road city of Kuqa in the south. Built between 1974 and 1983 by the Chinese military at tremendous cost — 168 soldiers lost their lives during construction — the highway remains one of the most extraordinary driving experiences on Earth.
What sets the Duku Highway apart from other scenic roads is the sheer variety of landscapes compressed into a single route. Over the course of 561 kilometers, you will pass through four distinct climatic zones. The journey begins in the arid Gobi-like foothills near Dushanzi, climbs through dense spruce forests and alpine meadows, crosses snow-capped passes above 3,000 meters, and descends into the sun-baked red canyons and desert landscape approaching Kuqa. It is not unusual to experience snow, rain, sunshine, and wind all in a single afternoon — locals joke that you can see all four seasons in one day on the Duku.
The elevation changes are staggering. From Dushanzi at roughly 600 meters above sea level, the road climbs to Hashilegen Pass at 3,390 meters before undulating through highland plateaus and descending again to Kuqa at around 1,000 meters. These dramatic shifts create constantly shifting panoramas: one moment you are navigating tight switchbacks carved into a cliff face, the next you are cruising across a vast grassland dotted with grazing horses and yurts.
The construction itself was a monumental feat. Over 13,000 soldiers spent nearly a decade blasting tunnels through solid granite, bridging raging glacial rivers, and carving the roadbed into mountainsides that had never seen a human road. The highway was originally built as a strategic military supply route, but today it serves as a lifeline for local communities and a bucket-list adventure for travelers from around the world. For more context on the region's history and logistics, see our Xinjiang transportation guide.
The Duku Highway is a seasonal road, closed for roughly eight months of the year due to heavy snowfall and avalanche risk in the Tianshan passes. The opening and closing dates are not fixed — they depend on weather conditions and are announced by the Xinjiang Department of Transportation each year.
Typical opening window: The road usually opens between June 5 and June 15, though in some years with lighter snowfall it has opened as early as late May. In 2025, the highway opened on June 10.
Typical closing window: Closure generally occurs between October 5 and October 15, sometimes earlier if an early winter storm brings heavy snow to the passes.
June: The road has just opened, and the scenery is at its greenest. Wildflowers blanket the meadows, snow still clings to the highest peaks, and rivers run high with glacial meltwater. The downside is that some sections may still have mud or debris from winter, and weather is unpredictable. This is an excellent time for landscape photography in Xinjiang.
July and August: Peak season. The weather is most stable, daytime temperatures in the valleys reach a pleasant 20-28°C, and all services along the route are fully operational. This is when most travelers visit, and you can expect more traffic, particularly on weekends. Book accommodation well in advance if traveling in August.
September: Perhaps the most beautiful month. The grasslands turn golden, the air is crisp, and the light takes on a warm, amber quality that photographers adore. Autumn colors begin appearing in the forests by mid-September. Crowds thin significantly after the first week. However, nights become cold (near freezing at higher elevations) and the risk of early closure increases after mid-September.
October: The road may still be open in early October, but closure can happen at any time. Only attempt the drive in early October if you are flexible with your plans and have warm clothing. The autumn scenery can be spectacular, but the risk of being stranded by a sudden snowstorm is real.
The Duku Highway follows China National Highway G217 through the Tianshan range. Here is a segment-by-segment overview of the route from north to south, with approximate distances and driving times under good conditions:
| Segment | Distance | Driving Time | Highlights |
|---|---|---|---|
| Dushanzi to Hashilegen Pass | ~130 km | 2.5-3 hrs | Dushanzi Canyon, steep mountain switchbacks, alpine forests |
| Hashilegen Pass to Nalati | ~80 km | 1.5-2 hrs | High-altitude pass views, descent into Nalati valley |
| Nalati to Bayanbulak | ~90 km | 2-2.5 hrs | Nalati Grasslands, rolling plateau scenery |
| Bayanbulak to Tianshan Grand Canyon | ~130 km | 2.5-3 hrs | Swan Lake viewpoint, Iron Pass (Tie Pass), red canyon entrance |
| Tianshan Grand Canyon to Kuqa | ~130 km | 2-2.5 hrs | Kizilya Red Cliffs, desert landscape, Kuqa city |
Total distance is approximately 561 kilometers, with a total driving time of roughly 10-13 hours depending on road conditions, stops, and traffic. Most travelers spread this over 2-3 days. For those planning a broader self-drive trip, our self-driving Xinjiang guide covers vehicle preparation, permit requirements, and route planning in detail.
The highest point on the Duku Highway, Hashilegen Pass offers sweeping 360-degree views of snow-capped peaks stretching to the horizon. On a clear day, the panorama is breathtaking — you can see for dozens of kilometers in every direction across the Tianshan range. There is a small parking area at the top where travelers stop to take photographs and, if conditions allow, walk short distances along the ridgeline. Temperatures at the pass can drop below zero even in July, so bring a warm jacket regardless of the season.
Often called the most beautiful grasslands in Xinjiang, the Nalati Grasslands spread across a high plateau of rolling green hills dotted with wildflowers, grazing horses, and the occasional Kazakh yurt. The grasslands sit at roughly 2,000 meters elevation and are best visited in the late afternoon or early morning when the light is golden and the tourist buses have not yet arrived. Horseback riding is available, and several viewpoints along the road offer postcard-perfect vistas without requiring a hike.
The Bayanbulak wetlands, known as Swan Lake, are a high-altitude marshland where whooper swans, gray cranes, and other migratory birds gather during the summer months. The best viewing is from a designated observation platform that overlooks the winding Kaidu River as it threads through the wetlands. Sunset here is legendary — the setting sun turns the water golden and the surrounding mountains deep purple. The nearby town of Bayanbulak makes a natural overnight stop. See our dedicated Kuqa and Bayanbulak guide for more details on accommodation and logistics in this area.
As the highway descends from the highlands toward the Tarim Basin, it passes through a dramatic red-rock canyon that rivals anything in the American Southwest. The Tianshan Grand Canyon features towering sandstone walls, narrow slot canyons, and bizarrely eroded rock formations in shades of red, orange, and ochre. There are several pull-off points along the road where you can stop and walk short trails into the canyon. The scale is immense — canyon walls rise 200 meters or more above the road.
Near the southern end of the highway, the Kizilya (Red Cliffs) formation is a vast expanse of wind-sculpted red sandstone that looks like the surface of Mars. The name literally means "red cliff" in Uyghur. This area is particularly stunning in the late afternoon when the low sun intensifies the red coloration. It is also one of the best photography locations along the route. The geological formations here are part of the same rock system as the nearby Tianshan Grand Canyon but offer more accessible viewpoints right beside the road.
The Duku Highway corridor offers excellent trekking opportunities — see our Xinjiang trekking guide for specific trail recommendations.
Accommodation along the Duku Highway ranges from basic guesthouses to surprisingly comfortable hotels. The key overnight stops are Nalati town and Bayanbulak town, both of which have developed tourist infrastructure in recent years.
Nalati Town: This is the most popular first-night stop and offers the widest range of accommodation. Options include several mid-range hotels (200-500 CNY per night), Kazakh-style yurt experiences on the grasslands, and a handful of upscale boutique properties. During peak season (July-August), rooms book out quickly and prices can double. Booking at least two weeks in advance is essential. The town has restaurants serving Uyghur, Kazakh, and Chinese cuisine.
Bayanbulak Town: Smaller and more remote than Nalati, Bayanbulak offers fewer but adequate lodging options. The best hotels are basic three-star properties (150-400 CNY), and there are several guesthouses run by local Mongol families. The town sits at roughly 2,500 meters elevation, so nights are cold even in summer. Heating is available in most hotels but confirm this when booking. The advantage of staying here is proximity to Swan Lake for sunset viewing.
Kuqa: If you complete the drive in two days or push through to the southern end, Kuqa is a proper city with full hotel options from budget to four-star. It makes a natural endpoint for the Duku Highway journey and connects onward to the southern Xinjiang circuit.
For travelers seeking a more adventurous experience, camping on the Nalati Grasslands or in designated areas near Bayanbulak is possible, though you should bring all supplies and warm gear. Our Xinjiang packing list covers everything you need for a multi-day Duku Highway trip.
The Duku Highway is a real mountain road, not a scenic expressway. While the pavement is generally good, the driving conditions demand attention and preparation. Here are the essential tips for anyone planning this drive:
Fuel strategy: Fill up at every gas station you see. There are only 6-8 stations along the entire 561km route, and the longest stretch between stations can exceed 150km. Stations in Dushanzi, Nalati, and Bayanbulak are the most reliable. Carry an approved spare fuel container (5-10 liters) for emergencies. Some smaller stations may only accept cash, so carry sufficient yuan.
Weather changes: Conditions can shift dramatically within an hour. A sunny valley can turn into a rainstorm on the next pass, and snow is possible at high elevations even in July. Carry rain gear, warm layers, and sunglasses. Check weather forecasts each morning, but understand that mountain weather is inherently unpredictable.
Altitude sickness: The road crosses two passes above 3,000 meters. While most travelers do not experience severe altitude sickness at these elevations, mild symptoms like headache and shortness of breath are common. Stay hydrated, avoid alcohol the night before crossing high passes, and consider bringing altitude medication or portable oxygen canisters if you are sensitive.
Road conditions: The road is paved but narrow in places, with steep drop-offs and limited guardrails on some sections. Landslides and rockfalls can temporarily block the road after heavy rain. Speed limits are strictly enforced with frequent speed cameras. Expect average speeds of 40-60 km/h in mountain sections.
Checkpoints: There are several security checkpoints along the route where police will check your ID (passport for foreigners) and vehicle registration. Keep documents easily accessible. Foreign travelers may be asked additional questions. A local driver-guide can help navigate these smoothly.
Vehicle requirements: A well-maintained SUV or sedan with good brakes and tires is sufficient. Four-wheel drive is not required under normal conditions but provides extra confidence on gravel sections or after rain. Before departing, check tire pressure, brake fluid, coolant levels, and ensure you have a spare tire and basic tools.

This itinerary balances driving time with sightseeing and assumes you are traveling with a private driver, which we strongly recommend for this route. Solo drivers should add extra time for rest stops.
Depart Dushanzi early morning (around 8:00 AM). Stop at Dushanzi Canyon for photographs of the dramatic river gorge just outside town. The road climbs steeply through forested mountains with increasingly dramatic scenery. Stop for lunch at a roadside restaurant near the midpoint. Cross Hashilegen Pass in the early afternoon — allow 30-45 minutes for photos and a short walk at the top. Descend into the Nalati valley and arrive at Nalati town by late afternoon. Spend the evening exploring the grasslands on foot or horseback and enjoy a Kazakh-style dinner. Overnight in Nalati.
A shorter driving day allows time to fully enjoy the Nalati area. After a leisurely breakfast, take a morning drive through the Nalati Grasslands, stopping at viewpoints along the way. The road between Nalati and Bayanbulak crosses rolling highland plateaus with stunning views in every direction. Arrive in Bayanbulak by early afternoon. Visit the Mongol temple in town, then head to the Swan Lake observation platform for sunset — this is one of the most memorable moments on the entire Duku Highway. Overnight in Bayanbulak.
Depart Bayanbulak in the morning. The road climbs to Iron Pass (Tie La Pass) before beginning a long descent through the Tianshan Grand Canyon. Stop frequently at canyon viewpoints — each turn in the road reveals a new perspective on the red-rock formations. Continue through the Kizilya Red Cliffs area, then descend into the desert landscape approaching Kuqa. Arrive in Kuqa by late afternoon. The city offers excellent restaurants, a fascinating old town, and connections to onward travel across southern Xinjiang. For those continuing the adventure, Kuqa is a gateway to the Xinjiang adventure travel circuit.
Two legendary roads dominate the adventure travel conversation in western China: the Duku Highway and the Karakoram Highway (KKH). Both are extraordinary, but they offer very different experiences.
The Duku Highway is shorter (561 km vs. 1,300 km for the full KKH), stays at lower maximum elevation (3,390 m vs. 4,733 m at Khunjerab Pass), and passes through more varied landscape types. The Duku is primarily about natural beauty — grasslands, forests, canyons, and mountain passes — and can be driven in 2-3 days. It is generally more accessible and requires fewer permits.
The Karakoram Highway, by contrast, is about extreme altitude and cultural immersion. It passes through the Pamir plateau, skirts enormous peaks like Muztagh Ata (7,546 m), and traverses the culturally rich Tashkurgan valley with its Tajik communities. The KKH requires an Alien Travel Permit and a registered guide, and the full route from Kashgar to the Pakistan border takes 3-4 days. For travelers with time to do both, the Duku and KKH complement each other perfectly and can be combined into a single epic Xinjiang road trip. See our Xinjiang itinerary planning guide for route combinations.
