If you’re planning a road trip in Xinjiang, the Duku Highway is the single most dramatic route you can take. It stretches 561 kilometers from Dushanzi in the north to Kuche in the south, cutting straight through the Tianshan Mountains. The must-see stops are not just scenic pull-offs; they are geological and cultural landmarks that define the journey. Start at Dushanzi Grand Canyon (mile marker 0), a 200-meter-deep fissure carved by the Kuitun River, then climb to Hashangou Mining Area (around kilometer 70) for the first real taste of alpine terrain. Next, Qiaoerma (kilometer 180) offers the iconic “S-curve” road that photographers obsess over. The Bayingbulak Grassland (kilometer 320) is the world’s second-largest grassland, covering 23,000 square kilometers, where you can spot wild swans at the Swan Lake. Finally, Kuche Grand Canyon (kilometer 500) presents red sandstone cliffs that date back 250 million years. Each stop has a distinct elevation, climate, and ecosystem—from snow-capped peaks at 3,400 meters to arid desert valleys at 1,000 meters.

The highway is only open from June to September, typically 100 to 120 days per year, because snow can accumulate up to 8 meters deep in winter. In 2023, over 3.5 million vehicles traveled this road, according to Xinjiang transport authorities. The elevation profile is brutal: you start at 450 meters in Dushanzi, climb to 3,400 meters at the Laerdundaban Pass (kilometer 280), then descend to 1,000 meters in Kuche. That’s a 2,950-meter swing in a single day. The road has 280 bridges and 60 tunnels, including the 2.5-kilometer-long Hashangou Tunnel, which was drilled through solid granite. Temperature swings are equally extreme: at the pass, it can hit -5°C at night, while the Kuche basin can reach 40°C in July. Pack for four seasons in one trip.
The first mandatory stop is Dushanzi Grand Canyon, located 12 kilometers south of Dushanzi city. The canyon walls are composed of Jurassic-era sandstone, with vertical drops of 200 to 300 meters. The Kuitun River at the bottom flows at an average of 10 cubic meters per second, but after heavy rain, it can surge to 200 cubic meters per second. The best viewpoint is at the Glass Observation Deck, which extends 15 meters over the edge. Admission is 30 yuan, and parking is free. Most travelers spend 45 minutes here, but if you have time, hike the 2-kilometer trail along the rim. The canyon’s color shifts from beige to deep red depending on the angle of the sun—midday light is flat, but late afternoon (4:00 PM to 6:00 PM) creates dramatic shadows.
Next, Hashangou Mining Area (kilometer 70) is a ghost town from the 1970s, when the Chinese government extracted copper and iron here. The mine closed in 1998, but the rusted machinery and abandoned dormitories remain. The road here is narrow—only 6.5 meters wide—with hairpin turns that require speeds under 20 km/h. The elevation climbs from 1,200 meters to 2,800 meters over 30 kilometers. Watch for falling rocks; the slope is 45 degrees in some sections. There’s a small rest stop with a toilet (no running water) and a vendor selling bottled water at 5 yuan per bottle. The air here is thin, so if you’re not acclimated, take breaks every 15 minutes. The temperature drops 1°C for every 100 meters of elevation gain, so from the base to the top, you’ll lose about 16°C.
At Qiaoerma (kilometer 180), the road becomes the highlight. This is the most photographed section of the Duku Highway, with a series of switchbacks that look like a coiled snake from above. The elevation is 2,400 meters, and the road gradient is 8% in some spots. In 2021, the local government installed a viewing platform at the top of the S-curve, which can hold 50 people. The best time to shoot is sunrise (around 6:30 AM in July) when the light hits the road at a low angle, or just after rain when the asphalt is wet and reflective. The traffic here is heavy—up to 200 vehicles per hour during peak season—so be patient. There’s a small parking area that fills up by 10:00 AM. If you’re driving an RV, note that the maximum vehicle length allowed is 12 meters; longer rigs are banned on this section.
Bayingbulak Grassland (kilometer 320) is a 45-minute detour from the main highway, but it’s worth it. This is the largest alpine grassland in China, at an average elevation of 2,600 meters. The grassland supports 1.5 million sheep and 200,000 yaks, according to the local herders’ association. The Swan Lake area covers 1,000 hectares and is home to 3,000 whooper swans from March to October. Entrance is 65 yuan per person, plus 50 yuan for a vehicle. The best activity is a 4-hour horseback ride (200 yuan per hour) to the Nine-Bends and Eighteen-Turns viewpoint, where the Kaidu River forms a series of oxbow lakes. The water is crystal clear, with visibility up to 5 meters. The temperature here is mild—15°C to 25°C in summer—but rain is common, so bring a waterproof jacket. Camping is allowed in designated areas, with a fee of 50 yuan per tent.
Further south, Kuche Grand Canyon (kilometer 500) is a completely different world. The canyon is 5.5 kilometers long, with walls up to 300 meters high. The rock is red sandstone from the Cretaceous period, and the canyon floor is a dry riverbed that floods during July and August. The average rainfall here is only 50 millimeters per year, but when it rains, it can dump 30 millimeters in an hour, causing flash floods. The canyon has a single walking path that takes 2.5 hours to complete. Admission is 40 yuan, and there’s no shuttle—you walk the entire distance. The narrowest point is only 2 meters wide, and the walls are covered in salt deposits that sparkle in the sun. The temperature inside the canyon can be 10°C cooler than outside, but humidity is near zero. Bring at least 2 liters of water per person. The canyon’s geological strata are visible in the walls, with layers of sandstone, mudstone, and conglomerate that date back 120 million years.
Beyond the main stops, there are lesser-known spots worth a pause. The Nalati Grassland (kilometer 250) is a side road that leads to a 1,800-square-kilometer pasture. It’s less crowded than Bayingbulak, with only 50,000 visitors per year. The road is unpaved for 15 kilometers, so a 4x4 is recommended. The Tianshan Secret Cave (kilometer 400) is a natural limestone cave that was discovered in 2015. It’s 200 meters deep, with stalactites that are 10,000 years old. Access is limited to 20 people per day, and you need to book through the local tourism office. The Duku Highway Memorial Hall (kilometer 0, Dushanzi) is a free museum that documents the road’s construction from 1974 to 1983, when 168 workers died building it. The hall has 200 artifacts, including original tools, photos, and a 1:500 scale model of the entire route.
Logistics are critical. Fuel stations are sparse: there are only 6 along the entire 561-kilometer route, spaced 80 to 120 kilometers apart. The last station before the pass is at kilometer 200 (Qiaoerma), and the next is at kilometer 330 (Bayingbulak). Fill up at every opportunity. Cell service is non-existent for 40% of the route, particularly between kilometers 150 and 250, and again between kilometers 400 and 480. Download offline maps on Gaode or Baidu before you go. The speed limit is 40 km/h on most sections, with 60 km/h on straightaways. The police enforce this strictly—in 2023, they issued 12,000 speeding tickets on the highway. Carry a physical map as backup; the paper version from the Xinjiang Tourism Bureau is free at the Dushanzi visitor center.
Wildlife is abundant. The Tianshan area hosts 300 species of birds and 50 species of mammals. On the northern section, you’ll see Himalayan snowcocks (Tetraogallus himalayensis) near the pass, recognizable by their white underbellies. In the grasslands, Mongolian gazelles (Procapra gutturosa) graze in herds of 20 to 30 individuals. The Xinjiang wild ass (Equus hemionus) is rarer, with only 2,000 individuals left in the wild, but they are sometimes spotted near the Kuche end. The golden eagle (Aquila chrysaetos) is common, with a wingspan of up to 2.2 meters. If you see one, stop and watch—they hunt marmots and hares in the open grasslands. The local herders use Kazakh eagle hunters who train these birds, but you’ll only see them at festivals like the Naadam Festival in August.
Food options are limited but authentic. At Qiaoerma, there is a single restaurant that serves nang (flatbread) and lamb skewers for 10 yuan each. The Bayingbulak area has yurt restaurants where you can try kumiss (fermented mare’s milk) for 15 yuan per cup. The Kuche end has Uyghur-style pilaf (polo) with carrots and lamb for 25 yuan per plate. Avoid the roadside stalls that sell dried meat—it’s often not refrigerated and can cause food poisoning. Bring your own snacks: high-energy bars, nuts, and dried fruit are ideal. Water is the biggest issue; the tap water in the mountains is safe to drink from streams above 2,500 meters, but below that, it’s contaminated with livestock waste. Carry a portable filter or purification tablets.
Safety is non-negotiable. The Duku Highway has a fatality rate of 0.8 per 100,000 vehicles, which is higher than the national average of 0.2. The main risks are rockfalls, landslides, and driver fatigue. In 2022, there were 47 rockfall incidents that closed the road for a total of 120 hours. The most dangerous section is between kilometers 100 and 150, where the road is cut into a cliff face with a 200-meter drop on one side. Drive with your headlights on at all times, even in daylight. If you encounter a landslide, do not try to cross—reverse to the nearest safe spot and wait for road crews. The emergency number in Xinjiang is 110, but cell service is spotty, so a satellite phone is a good investment. The altitude sickness risk is real: at 3,400 meters, oxygen levels are 30% lower than at sea level. Symptoms include headache, nausea, and dizziness. Acclimate for 24 hours in Dushanzi before driving up.
The cultural aspect is often overlooked. The highway passes through Kazakh and Mongolian autonomous prefectures, where the local population is 80% ethnic minority. The Kazakh herders still practice transhumance, moving their livestock between summer and winter pastures. In July, you’ll see them on horseback, driving flocks of sheep across the road. Be respectful—don’t honk, and slow down to 10 km/h. The Uyghur communities in the south have a different culture: they are more settled, with a focus on agriculture (cotton, wheat, and grapes). The Kuche area is known for its Kizil Caves, a UNESCO World Heritage site with 236 Buddhist cave temples from the 3rd to 8th centuries. The murals inside are faded but still show scenes of the Buddha’s life. Admission is 70 yuan, and photography is banned inside to protect the pigments.
Environmental impact is a growing concern. The highway receives 1.5 million visitors per year, and the waste generated is 500 tons annually. The local government has installed 200 trash bins along the route, but they are often overflowing. In 2023, a volunteer group collected 12 tons of garbage in a single weekend. The Leave No Trace principle is critical: pack out everything you bring in, including toilet paper (which does not decompose in the dry climate). The grasslands are fragile; walking off-trail compacts the soil and kills the grass, which takes 5 years to recover. The swan population at Bayingbulak has declined by 20% in the last decade due to human disturbance. Stay at least 50 meters away from wildlife, and never feed them.
Timing your trip is everything. The highway opens in mid-June and closes in late September, but the exact dates depend on snow conditions. In 2023, it opened on June 10 and closed on September 25. The best time to go is late August, when the summer crowds have thinned (down from 15,000 vehicles per day in July to 8,000 in August), and the autumn colors start to appear. The larch trees turn gold in early September, and the grasslands are still green. Avoid the Chinese National Day holiday (October 1-7), when the road is closed for winter. The weather is most stable in July and August, with only 5 days of rain per month on average. But the trade-off is heat: the Kuche end can hit 40°C, so start your drive at 6:00 AM to avoid the worst of it.
Vehicle requirements are specific. The highway is paved, but the surface is rough in some sections, with potholes and cracks. A sedan can handle it, but a SUV is better for the unpaved detours. The clearance needed is at least 15 centimeters. Tires should be all-season, not summer tires, because the temperature at the pass can drop below freezing even in July. Check your brakes before the trip—the descent from the pass to Kuche is 50 kilometers of continuous downhill, which can overheat brake pads. Engine braking is recommended; use second or third gear on the steep sections. The fuel consumption is higher than normal due to the elevation gain; expect 15% more fuel usage than flat terrain. Carry a spare tire, a jack, and a tire repair kit. The nearest mechanic is in Dushanzi or Kuche; there are no repair shops along the route.
