Qilian Mountains

Mountain

The Qilian Mountains are a high, glacier-fed mountain range on the border between Gansu and Qinghai provinces in northwest China. Travelers come for alpine scenery, glaciers and historic passes and to see the rivers that feed the Hexi Corridor.

Address: Qilian Mountains, on the border of Gansu and Qinghai provinces, China

The Qilian Mountains form the northeastern escarpment of the Tibetan Plateau and mark the southwestern edge of the Hexi Corridor; the range stretches roughly 800 km southeast from south of Dunhuang. They are northern outliers of the Kunlun Mountains and include high peaks such as the eponymous Qilian Shan (about 5,547 m) and other higher summits further south.

The range is an important water source for the surrounding drylands: numerous small rivers and creeks flow northeast from the Qilian Mountains, supporting irrigated agriculture in the Hexi Corridor before the streams disappear into the Alashan Desert. The region contains many glaciers (the largest named Touming Mengke) that have been shrinking in recent decades.

The mountains support a characteristic conifer-forest ecosystem and include features such as the brackish Lake Hala, high alpine passes like Biandukou, and stretches of the Ming dynasty Great Wall along the northern slopes. Visiting the Qilian Mountains means remote, high-altitude landscapes with limited facilities, seasonal road closures and a strong contrast between green summer meadows and long, cold winters.

  • Glaciers (Touming Mengke): Large glaciers feed valley streams and are visible from certain ridgelines, but many have been retreating in recent decades.
  • High peaks and ridgelines: Snow-capped summits and sharp ridges provide expansive alpine scenery and panoramic views of the plateau edge.
  • Biandukou pass: A high historic pass linking Gansu and Qinghai that illustrates traditional transmountain routes and rugged terrain.
  • Ming Great Wall remains: Sections of the Ming dynasty Great Wall run along the northern slopes and can be seen where roads and trails approach the corridor.
  • Lake Hala and alpine meadows: Brackish Lake Hala and seasonal pastures support birdlife and traditional herding scenes in summer.
When to Go

Best Time to Visit Qilian Mountains#

Weather is cold for much of the year and the climate is tundra-like; travel windows depend on tolerance for cold and wet conditions.

Summer (best for access)
June - August · -2°C - 11°C (28°F - 52°F)
Warmest months with the greatest snowmelt and accessible high passes, but expect frequent rain and thunderstorms - plan for wet conditions and shorter daylight in storms.
Late spring and early autumn (shoulder seasons)
May - June, September · -6°C - 8°C (21°F - 46°F)
These months often offer clearer weather and cooler temperatures than midsummer, with less vegetation at very high elevations; some high routes may still be affected by late snow or early closures.
Winter (not recommended for most visitors)
October - April · -26°C - 1°C (-15°F - 34°F)
Very cold with heavy snow and widespread road closures, making travel into the high mountains difficult and services largely unavailable.

Getting There & Around

How to Get to Qilian Mountains#

The nearest regional centres on the Gansu side include Jiuquan, Jiayuguan City and Zhangye; these cities are the usual bases for road journeys into different parts of the range. Regional airports and railway stations are located at those cities, from which the final approach is by road.

The last stretch into mountain areas is by sealed or unsealed mountain roads and local tracks; hire a car, use a local driver or take regional coaches as available and expect long driving times to reach alpine passes and glacier viewpoints. Seasonal snow and landslides can close high roads, so check local conditions before you travel.

Tips for Visiting Qilian Mountains#

  • Prepare for high altitude and cold weather even in summer; allow time to acclimatize and watch for altitude sickness.
  • Services are limited in mountain areas - carry food, water, warm layers and a basic first-aid kit for remote travel.
  • Roads and passes can be closed or muddy in spring thaw and during summer storms; plan flexible itineraries.
  • Respect pastoral and protected areas and ask locally before entering grazing land or restricted zones.
  • Check whether you need permits for travel in border or protected areas and carry your passport and ID.
