Overview of Yizhao Highway
The Yizhao Highway, also known as Provincial Road S237 (Yining to Zhaosu section), spans approximately 120 kilometers. It is a shortcut through the heart of the Tianshan Mountains and one of Xinjiang's most scenic provincial roads. The route crosses the Angelate Pass at over 3,000 meters in elevation, offering breathtaking views of alpine meadows, primeval forests, snow-capped peaks, glaciers, gorges, and mountain streams. Compared to the Duku Highway, the Yizhao Highway is shorter, more challenging, and less crowded, making it ideal for self-drive travelers seeking an immersive experience away from the crowds. Its annual opening window is typically shorter than that of the Duku Highway, running from late June to the end of September, depending on snowmelt conditions.
Scenic Highlights Along the Route
Departing from Yining, travel south along S237. You'll first reach Tuohulasu Grassland, a lush high-altitude pasture where herds of cattle and sheep graze—this is the summer grazing ground for Kazakh nomads. Continue ascending into Baishifeng Scenic Area, where limestone peaks gleam white under the sun against a backdrop of blue skies and clouds, creating a breathtaking scene. Cross Angelite Pass, the highest point of the route at approximately 3,020 meters, offering panoramic views of the majestic snow-capped Tianshan Mountains. Descending into Zhaosu Basin in July, you'll witness golden rapeseed flowers stretching across the fields with distant snow mountains, painting a picturesque rural landscape. Visit Zhaosu Horse Farm, one of China's largest horse-breeding bases, to watch the legendary "Heavenly Horses Bathing in the River" performance.
Road Conditions and Driving Tips
Yizhao Highway has an asphalt surface but is narrow; some sections allow only two-way traffic to pass. Steep slopes and frequent curves before and after the mountain pass require cautious driving and speed control. During the rainy season, watch for rockfalls and mudslides by monitoring mountain conditions. The road is completely closed in winter due to heavy snow. Even during summer, sudden weather may cause temporary closures—always check real-time road conditions before traveling. SUVs or vehicles with high ground clearance are recommended; sedans can pass but must slow down. There are no gas stations along the route; fill up in Yining or Zhaosu before departure. Mobile signal is weak near the pass; download offline maps in advance.
Itinerary suggestions
Yizhao Highway is best experienced as part of the Ili Loop rather than a standalone trip. Recommended itinerary: Start from Yining, take Yizhao Highway to Zhaosu to explore rapeseed flower fields and the Xiahta Ancient Trail, then head through Tekes' Bagua City to Kalajun Grassland before returning to Yining for a 3–4 day in-depth Ili loop. Alternatively, combine it with Duku Highway by traveling from Zhaosu via Xiahta to the southern section of Duku Highway for a cross-Tianshan journey. The highway is most accessible between 7 and 8, when road conditions are favorable and scenery is at its peak. As an underrated gem route through the Tianshan Mountains, Yizhao Highway is a must-try for every self-driving enthusiast.
Worth stopping at along the way
Hidden gems await along the Yili-Zhao Pass route. Deep in Tuohulasu Grassland lies a wild peony field that blankets the hillsides in pink every mid-June—a true secret spot known to very few. At the Baishifeng Scenic Area's viewpoint, you can get up close with limestone formations; on clear days, the stark white peaks contrast beautifully against the blue sky, making it perfect for photos. The prayer flag阵 at Dawan Yarkot offers an excellent vantage point for capturing cultural landscapes; colorful flags fluttering in the wind against distant snow-capped mountains create stunning visuals. On your way down, stop by Zhaosu Wetland Park, a paradise for birdwatchers. In summer, rare species like black storks and demoiselle cranes can be spotted here.
Safe Driving and Emergency Preparedness
The Yizhao Highway is beautiful, but risks cannot be ignored. Before departure, check your brakes, tire pressure, and coolant. Frequent braking on long downhill sections can cause overheating and failure; use a low gear for engine braking instead. Do not overtake or stop to take photos on curves—blind corners make oncoming traffic unpredictable. On rainy days, reduced visibility and slippery roads warrant delaying travel rather than risking the journey. Carry ample water, high-calorie snacks, and warm clothing; there are no supply points near the passes, and emergency response times are slow. If you experience altitude sickness symptoms, descend immediately to a lower elevation. Travel in groups; solo vehicles are strongly discouraged. Two or more vehicles can provide mutual support and enhance safety.
