The Yizhao Highway runs from Yining County, crosses the Wusun Mountains, and reaches Zhaosu County. Spanning approximately 120 kilometers, this winding road with steep gradients offers a thrilling drive, reaching elevations close to 3,000 meters. It is one of the most exhilarating routes in Ili during the summer.
Operating dates are subject to snowfall; the road typically opens from June to September. Please check official announcements from local traffic and highway authorities for the current year's schedule. The route is often closed during winter and early spring due to snow accumulation.
I. Road Conditions and Driving
The road is primarily two lanes with frequent curves; some sections have cliffs on one side and deep valleys on the other. Trucks travel slowly uphill—check for oncoming traffic before overtaking. Speed limits and average speed enforcement vary by section. Do not guess your speed.
Temperature drops significantly with altitude: while it may be over 20°C at the base, expect around 10°C at the mountain pass. On long descents, brakes can overheat and lose effectiveness; use a lower gear to control speed safely.
- Opening Season: Typically 6 to 9, subject to the year's announcement.
- Total length: approximately 120 km; driving time: about 3 hours
- Maximum altitude: Nearly 3000 meters; low temperatures at the pass
- Not recommended: driving alone in rain or snow, at night, or for new drivers.
II. Where do I stop along the way?
The viewpoint on the ascent offers sweeping views of the Ili River Valley and is a popular stopping point. Near the pass, you'll find meadows with lingering snow; strong winds prevail, so stay brief.
After descending into Zhaosu, the view opens up to vast grasslands and farmlands. Livestock herders move along designated routes by the roadside; slow down and yield when animals cross.
III. Alternative Routes During Road Closures
If the road is closed, you can take an alternative route via Yining through Tekes to Zhaosu. Although longer, this route offers stable conditions and is open year-round. The detour passes through Bagua City, offering a convenient opportunity for a stopover.
Zhao's rapeseed flowers bloom in July, coinciding with the opening of the Yizhao Highway—the road's busiest season. Book accommodations and vehicles in advance during the flowering period.
IV. What preparations are needed to open this road?
Vehicle Check: Day Before Departure – Brake Pad Thickness, Tire Tread Depth, Coolant Level, and Wiper Blades. On long downhill descents, use gear control to manage speed; avoid prolonged braking. If you smell burning, stop to let the brakes cool.
Carry a thick jacket, water, and basic tools. Cell service is weak near the pass; download route screenshots beforehand and share your estimated arrival time with companions.
If anyone in your group is prone to motion sickness, sit in the front seat and roll down the window during the uphill climb. Avoid taking photos while driving through winding sections; stop at designated scenic viewpoints instead.
Travel during opening hours: morning departures are more reliable. Fewer vehicles and better lighting in the morning leave room to adjust if temporary restrictions occur. On your afternoon return, watch for oncoming traffic and avoid crossing the centerline on curves.
Accommodation in the Zhaosu area is primarily available in the county town and near scenic spots; lodging becomes scarce during the July canola flower season. For a comprehensive self-drive itinerary in Ili, seeIli RouteCombining Zhaosu and XiataSumu Xiata Itinerary。
Fill up at the last gas station before heading uphill—there are no refueling points on the mountain. Pack a windproof jacket and gloves in the car; winds at the pass are much stronger than below, dropping the feels-like temperature by over 10°C.
If traveling with children, be aware that the winding roads may cause motion sickness. Eat light before departure and bring plastic bags and wet wipes. After descending into Zhaosu County, the road becomes flatter; you can pull over at a safe spot to rest.
