Gansu in December: Real Winter and the Start of the Quiet Season
December is the beginning of deep winter. It is very cold. Many services are reduced. But the major sites — Mogao, Danxia, Jiayuguan — remain open with almost no visitors. For the determined winter traveler, December offers the most solitary, stripped-down version of the Silk Road.

Gansu in December: Real Winter and the Start of the Quiet Season
December in Gansu is not a casual trip. The temperatures are serious: -10°C is a warm day in Dunhuang. The wind along the Hexi Corridor can be punishing. Many hotels have closed for the season. But if you have traveled in real winter before — if you have been to Mongolia in December, or the Canadian prairies, or northern Hokkaido — you know what to expect. And what you get in return is a Gansu that almost no one sees: empty, silent, severe, and unforgettable.
December conditions
Lanzhou: daytime 0-5°C, nighttime -10°C to -5°C. Smog can be significant. The city functions normally, and indoor attractions (museum, restaurants, tea houses) are unaffected.
Zhangye and Jiayuguan: daytime -3°C to 3°C, nighttime -15°C to -8°C. Wind chill is the main challenge. Clear days are crisp and beautiful; overcast days are harsh.
Dunhuang: daytime -2°C to 4°C, nighttime -15°C to -8°C. The desert cold is penetrating. Major hotels stay open; smaller ones close.
Southern Gansu: not viable. Temperatures below -20°C at altitude. Most accommodations closed. Roads may be impassable.
Why December might still be your month
Absolute solitude. December visitor numbers at Mogao are perhaps 3-5% of July levels. You may be the only person in your tour group. The caves feel completely different when you are alone with them.
The stark beauty of the winter desert is genuinely moving. The low sun, long shadows, and complete silence create an atmosphere that the busy months cannot reproduce.
Snow on the Danxia. It is not guaranteed, but when it happens — the rainbow stripes peeking through fresh snow — it is one of the most remarkable landscapes in China.
Prices are at their absolute lowest. December is the cheapest month to travel Gansu by every measure.
December survival guide
Clothing: thermal base layers, heavy fleece or wool mid-layer, expedition-weight down jacket, windproof outer shell. Insulated waterproof boots. Multiple pairs of wool socks. The warmest gloves and hat you own. Hand warmers. A thermos is not optional — hot water throughout the day makes a real difference.
Accommodation: book major chain hotels (or the best-rated local options) with confirmed heating and hot water. Do not try to save money on accommodation in December. A cold hotel room after a cold day outdoors is miserable.
Pacing: build in more downtime than you would in other months. You cannot spend 8 consecutive hours outdoors in -10°C. Plan museum visits, long meals, and rest periods between outdoor sessions.
Transport: trains are the most reliable winter option. Flights to Dunhuang can be delayed by winter weather. Build buffer time into the itinerary.
