If Xinjiang has a religion, it’s the road. And three highways are its cathedrals: G217, G218, and G314. Between them they contain the Duku Highway, the Taklamakan crossing, the green heart of Ili, and the roof-of-the-world Karakoram. Understanding these three routes is understanding the geography of a Xinjiang road trip — which one to take, when it opens, and what each will ask of you. This is the byways briefing.
G217 — the north–south spine (and the Duku)
The G217 runs north–south through the Tianshan, and its most famous segment is the Duku Highway (Dushanzi–Kuqa), a 561 km ribbon that climbs from flaming red canyons to snow passes in a single, absurd day. The rest of the G217 continues north to Karamay and south toward the Taklamakan’s edge. Key facts:
- Opens: early June, with the snowmelt; closes: late September–October.
- Why drive it: it’s the single most beautiful road in China, full stop (our Duku guide has the detail).
- Watch: altitude, weather flips, and the seasonal closure — plan exits north or south before it shuts.
G217 — the desert crossing (Taklamakan)
A different arm of the G217 (with the G3012) lets you actually cross the Taklamakan, the largest shifting-sand desert on Earth. This is the “sea of sand” drive: 200+ km of pavement, rail, and wind, with service stations at intervals. It’s hypnotic and humbling. Our Taklamakan guide covers it; the rule is simple — never leave the pavement, fuel at every chance, and don’t do it in a vehicle you don’t trust.
G218 — the Ili Valley loop
The G218 arcs through the Ili Valley, the green, humid heart of northern Xinjiang where the mountains trap moisture and the grasslands explode. It connects Yining, the grasslands (Nalati, Gongliu), and the eastern approaches, and it’s the backbone of the Yili grassland loop. Unlike the dramatic G217, the G218 is gentle and lush — poplars, meadows, and the occasional lavender field (July). It’s open most of the warm season and is the easiest “wow” drive for families.
G314 — the Karakoram (and the Pamir)
The G314 runs from Urumqi south through Korla and on to Kashgar, then beyond into the Pamir as the Karakoram Highway (KKH), climbing toward Tashkurgan and the Khunjerab Pass on the Pakistan border. This is the high, raw one:
- Kashgar → Tashkurgan: ~190 km of rising drama; requires a Border Defense Permit.
- Onward to Khunjerab: only with the right permits and a Pak-China plan (see the Khunjerab guide).
- Why drive it: the Pamir wall — Muztagh Ata, Baisha Lake, Karakul — is unlike anything else in the province.
How they fit a trip
- First-timer north loop: G218 (Ili) + the Duku segment of G217.
- Grand loop: G217 (Duku) → G3012 south → G314 up to the Pamir.
- Desert obsession: G217/G3012 Taklamakan crossing.
- The 15-day grand loop strings all three into one arc.
Seasons and closures (the big caveat)
All three are weather-bound. The Duku (G217) and the high Pamir (G314) close for snow; the G218 stays open but gets muddy in wet spells. Always check current status — our summer road alerts and winter closures track the openings. The best-time guide has the month-by-month.
Driving character
- G217 (Duku): tight, vertical, spectacular — daylight and sober only.
- G217 (desert): straight, empty, hypnotic — watch fatigue and fuel.
- G218: flowing, green, easy — the relaxing one.
- G314 (Pamir): high, exposed, permit-gated — plan ahead.
FAQ
Which is the most scenic? The Duku segment of G217, for most. The Pamir (G314) is the most otherworldly.
Can I drive all three in one trip? Yes — that’s the grand loop. Budget 15 days.
Are they paved? Yes, all three are fully paved; the challenge is weather and permits, not surface.
Do I need 4×4? No for the highways themselves; an SUV is plenty (see the vehicle guide).
Final word
Three highways, three kinds of sublime. Learn their rhythms — when they open, what they ask, where they go — and the whole map of Xinjiang clicks into place. Then pick your cathedral and drive.
