Bayanbulak & Kalajun Grasslands巴音布鲁克·喀拉峻 · Bāyīnbùlǔkè · Kālājùn
Two alpine grasslands on opposite shoulders of the Tianshan: Bayanbulak, a high basin where the Kaidu River coils into nine sunset-lit bends beside China's biggest swan reserve, and Kalajun, a UNESCO-listed 'sky grassland' of rolling flower meadows above deep spruce gorges. Together they're the heart of an Ili-valley road trip.
Grasslands with mountains in the room.
These are the anti-steppe grasslands: instead of flat immensity, the Tianshan's meadows roll and pitch at 2,000-2,600 m with snow ranges crowding every sightline. Bayanbulak fills a high basin where the Kaidu River loops into nine bends that catch fire at sunset beside China's biggest swan reserve; Kalajun — inscribed in the UNESCO Xinjiang Tianshan listing — is the 'sky grassland,' a rolling upland of June wildflowers breaking off into spruce-dark gorges.
They anchor the great Ili valley road trip, linked in season by the Duku Highway — a road that climbs from desert through canyon to glacier and back down into meadow in a single day and belongs on any list of Asia's great drives. Kazakh and Mongol herding camps run through it all; this is working transhumance you're driving through, not scenery behind a fence.
What this place is for.
- Wait out the sunset at Bayanbulak's Nine Bends platform, when the Kaidu River turns to ribbons of molten light
- Scan the swan lake reserve — whooper swans summer here in the thousands
- Ride or walk Kalajun's flower terraces in June, when the 'five-flower meadow' bloom rolls over the hills
- Drive the Duku Highway between them — one of Asia's great mountain roads, canyon to glacier to meadow in a day
Timing is most of the trip.
June is wildflower season on Kalajun's rolling 'sky grassland'; June-September works for both, with Bayanbulak's swan lake active all summer. The Duku Highway opens roughly June to early October — outside that window the loop doesn't connect.
These are working Kazakh and Mongol herding grasslands — summer yurt camps, horse herds moved to altitude, and kumis (fermented mare's milk) offered at the door; Kalajun is inscribed within the UNESCO Xinjiang Tianshan listing.
For foreign travelers.
- Build the trip as a driven loop from Yining or Korla — distances are serious and public transport reaches gateways, not gates.
- Confirm the Duku Highway's opening dates for your year; it decides the whole route.
- Weather at 2,000-2,600 m turns fast: pack a warm layer and rain shell even for July.
- Expect passport checks at scenic-area gates and highway checkpoints; build slack into driving days.
