The Eighteen Bends of the Sky Road is located on the Jianziwan Mountain on National Highway 318. The Tibetan name of Jianziwan Mountain is "Remanaza", which means Sheep Pass. The pass is about 4,659 meters above sea level. Although it does not exceed 5,000 meters, it is also the highest pass on National Highway 318 through the Kangba area. In order to facilitate tourists to rest and view the scenery here, an observation deck is built on the pass. When a drone is raised to overlook, the Eighteen Bends of the Sky Road has a shocking curvaceous beauty. The winding mountain road is like a giant dragon hovering in the mountains, giving people a sense of panoramic view of thousands of mountains and valleys.
