How long is the train from Lanzhou to Dunhuang?

About 7 hours 45 minutes to 9 hours depending on the service. D2749 leaves Lanzhou West at 11:58 and reaches Dunhuang at 19:42, 7 hours 44 minutes, from roughly CNY 324-344.

Is it better to fly or take the train from Lanzhou to Dunhuang?

The flight is about 1 hour 50 minutes against 7 to 9 hours by rail, and fares are sometimes under CNY 300, so flying is usually cheaper in time and often in money. The train wins if you want to stop at Zhangye and Jiayuguan on the way, which is the classic Hexi Corridor route.

How do foreign passport holders book Chinese train tickets?

Register on the official 12306 app with your passport number and buy there, or book through Ctrip/Trip.com, which adds a small booking fee but accepts foreign cards. Bring the passport you booked with; it is read at the station gate instead of a paper ticket.

Lanzhou to Dunhuang: trains, flights and what each one really costs you

Last verified 22 September 2026 · Timetable data: Ctrip and 高铁网 listings for summer 2026 · Re-check 12306 before booking

Lanzhou is where most international trips to Gansu begin — direct flights from Beijing, Shanghai, Chengdu and abroad, then one long haul west. Dunhuang is 1,050 km away along the Hexi Corridor. There are two ways to do it, and one of them lets you see Zhangye and Jiayuguan on the way.

The numbers

	Train (D-series)	Flight
Time	7h44m to about 9h	About 1h50m
Example	D2749: Lanzhou West 11:58 → Dunhuang 19:42	Evening services, e.g. Lanzhou 19:55 → Dunhuang 21:45
Typical fare	From about CNY 324–344 second class	Seen from about CNY 200 on the Dunhuang–Lanzhou direction (discounted); CNY 700–1,300 undiscounted
Stops you can break	Zhangye, Jiayuguan	None
Arrival	Dunhuang station, about 13 km from the city	Dunhuang airport, about 13 km from the city

Fares move with demand and season; the discounted air fares appear on shoulder-season dates. Always price both for your actual dates.

Option A — the train, corridor by corridor

The line runs Lanzhou West → Zhangye West → Jiayuguan South → Dunhuang, which is exactly the order most people want to travel it. Buy it as legs rather than one ticket if you plan to stop:

Lanzhou West → Zhangye West: a few hours up the corridor; the Rainbow Mountains (Danxia) are reached from Zhangye.
Zhangye West → Jiayuguan South: short hop; the fort and the Great Wall's western end are here.
Jiayuguan South → Dunhuang: the long western stretch into the desert.

Direct Lanzhou → Dunhuang services also exist if you would rather skip the stops, and conventional overnight trains run the same corridor for travellers who want to sleep through it.

Booking with a foreign passport

12306 (official app/website) works with a passport number and is the cheapest and most complete source of seats, including releases 15 days ahead.
Ctrip / Trip.com accept foreign cards and add a small service fee; useful when 12306's identity check refuses your document type or when the app is fighting your phone's region settings.
Your passport is the ticket — it is read at the gate. No printing needed.
Second class is fine for this route; upgrade to first on the 8-hour run if you want elbow room and a quieter carriage.

Option B — fly, but watch the airport transfer

Lanzhou's airport, Zhongchuan (LHW), is about 70 km from the city centre with a dedicated rail link to the city and Lanzhou West — allow an hour and do not cut it close.
Dunhuang (DNH) is small and quick: about 15–20 minutes to town, taxis and hotel pickups are easy.
Flights are frequently delayed in spring sandstorms (April–May) — a reason to keep the flight early in your trip rather than on the last day.

Getting around once you arrive

Dunhuang city → Mogao Caves: you do not go to the caves directly. Go to the digital exhibition centre, which is where tickets are checked; taxis and hotel shuttles run there in about 15 minutes from the centre.
Dunhuang → Mingsha / Crescent Lake: inside the city, 10 minutes by taxi.
The western line (Yumen Pass, Yardang): roughly 180 km of desert each way, effectively car-only. A private car for the day costs about CNY 566–1,000 for the vehicle, which is why two or more travellers should always compare against per-person tours.
Zhangye → Danxia: the scenic area is about 40 km from the city, with shuttle buses from the north gate; a taxi or day car is the norm.

Booking windows cheat-sheet

Mogao Caves tickets at 30 days, train seats at 15, Dunhuang hotels tightening from May. One email with the dates to circle for a corridor trip.
