Duku Highway Complete Guide: China's Most Beautiful Road, Open Only 4 Months a Year—How to Do It Right

The Duku Highway—the Dushanzi-to-Kuqa section of G217 National Highway—runs 561 km across the Tianshan range. It opens only from early June to late September each year (exact timing depends on snowmelt speed). On this road you can see desert, canyon, snow mountain, glacier, grassland, and forest all in a single day—six landforms in eight hours.

But precisely because it opens only four months a year, everyone crowds into those months. July-August traffic jams can stretch all the way from Qiao'erma to Nalati. This guide skips the fluff—when to go, which direction, where to sleep, how to dodge the jams.

🚙 Veteran Truth: The Duku Highway Has Hard Requirements for Vehicles

The entire Duku is paved, but it's all switchback mountain road, with a highest elevation of 3,400m (Haxilegen Daban). Vehicles over 7 seats are restricted on some segments (Dushanzi to Qiao'erma). Buses can't do the full route at all—too many curves, too narrow, too dangerous to pass.

The Prado is the best vehicle for the Duku Highway. High clearance handles mudslide-washed segments, spacious cabin keeps the trip comfortable, 4WD stays steady on the Haxilegen Daban snow section. Most critically—a veteran driver knows the most congested times and detour plans each year. He'll drag you out of the hotel at 6 AM to catch the first batch through Qiao'erma—you keep sleeping in the back, and he'll wake you to see the Tianshan sunrise out the window.

🗺️ The Duku Itinerary, 2 Days

Direction Choice: Dushanzi → Kuqa (North to South)

Going north-to-south, the elevation change is more sensible—from Dushanzi (500m) slowly climbing to Haxilegen Daban (3,400m), then descending all the way to Kuqa (1,000m). Going the reverse, you'd jump from 1,000m to 3,400m in an hour—altitude sickness odds spike.

Day 1: Dushanzi — Qiao'erma — Nalati (about 250km)

  • Pitfall Alert: The Dushanzi-to-Qiao'erma segment is the most dangerous—"Tiger Mouth" is carved into a cliff face above a hundred-meter-deep river valley. This section is landslide-prone in rainy season. You must stop at the Qiao'erma Martyrs' Cemetery—168 road-building soldiers rest here. The Duku Highway cost one life every 3 km on average. Go see them—that's the most basic respect for this road.
  • Veteran Tip: Haxilegen Daban (3,400m) has snow even in summer. Stop 10 minutes for photos—put on a down jacket and experience playing in snow in June. Overnight in Nalati—the Nalati grassland sunset spills gold across forest and meadow.

Day 2: Nalati — Bayinbuluke — Kuqa (about 300km)

  • Bayinbuluke: China's second-largest grassland. The Kaidu River's "Nine Bends and Eighteen Curves" at sunset can reflect nine suns (nine light points lined up on the water surface). Best effect only for a few days around the summer solstice.
  • Kuqa Grand Canyon: The Tianshan Mystery Grand Canyon—red Yadan landform like a wound sliced open by a knife. At midday, sunlight shoots through the gap at the canyon top, and the walls glow red as if on fire.

🎒 Hard Tips: Duku Essentials

⚠️ Don't Say I Didn't Warn You: The Duku Highway has no service areas the entire way, and few proper food stops. Stock up on supplies the day before in Dushanzi or Nalati—water, snacks, lunch all carried in.

  • Hard-shell jacket + thin down (Haxilegen Daban can hit zero even in summer)
  • Sunscreen + sunglasses (entire route at 2,000-3,400m)
  • Motion sickness meds (500+ km of switchbacks)
  • Snacks + water (limited roadside supplies)
  • Power bank (photos the entire way)

💡 Heart-to-Heart Truths

Don't go mid-July to mid-August: Traffic jams can stretch from Qiao'erma to Nalati—80 km. Late June or late August—snow still around or just starting, grass at its greenest, fewest cars.

Leave early every day: The Duku Highway's scenery is best in the morning—Qiao'erma morning mist, Nalati morning light. Afternoon is backlit + crowded. 6 AM departure, first batch through Haxilegen Daban.

Gas stations: Available in Dushanzi and Nalati; Bayinbuluke has one but frequently runs dry. Fill up before departure.

📸 Don't Shoot Blindly—These Spots Are Amazing

  • Haxilegen Daban: In summer, stand in the snow and shoot the green valley behind—winter and summer in one frame.
  • Bayinbuluke Nine Bends: Arrive at the viewpoint 1 hour before sunset to grab a spot. Telephoto for the nine suns reflected on the river bend.
  • Kuqa Grand Canyon: 12 PM - 2 PM, light shoots through the gap at the canyon top—walls look like they're on fire.

💬 What RoamFun Travelers Say

"Did the Duku in mid-June. Haxilegen Daban still had two-meter-high snow walls on the roadside—the car threaded through the snow walls, then descended into Nalati where it was all green grass and wildflowers. One morning from winter into summer. That's the Duku." — Ahuo, Chengdu ⭐⭐⭐⭐⭐

"At the Qiao'erma Martyrs' Cemetery, I read every name on the tombstones. The youngest was just 18 when he died. After coming out, nobody said a word. Behind this road's grandeur is the price of 168 young lives." — Laofang, Beijing ⭐⭐⭐⭐⭐

The Duku Isn't Something You Conquer—It's Something That Allows You to Pass

561 km, 168 road-building soldiers' lives, open only 4 months a year—from start to finish, the Duku Highway is a privilege. It's not that you have a car so you can drive it—it's that the road agrees to let you through.
