Where does the S217 road start and end?
The S217 runs northwest to southeast, starting in Xiewuzhen (Qinghai) and ending in Manigangezhen (Sichuan). It is a vital link between the Yushu region and the northern Sichuan trade routes. The drive takes you through the heart of the Khampa Tibetan region, crossing several massive ridges that separate the river basins of the plateau.
How challenging is the driving on S217?
While the road is entirely paved, it is long and physically demanding. The route crosses three major passes above 4,400 meters: Ngamba La (4,583m), Muri La (4,569m), and Sala La (4,459m). Some ramps are extremely steep, with gradients hitting 16%. These sections put heavy stress on engines and brakes, especially in the thin air where oxygen levels are significantly lower than at sea level.
What is the scenery like along the S217?
This is classic nomad country. The road crosses wide, high-altitude plains where you will see countless yaks and horses. The local Tibetan nomads still move their herds according to the seasons, and their black yak-hair tents are a common sight. To the south, the road offers distant and dramatic views of the Chola Mountains, known for their jagged glaciated peaks.
What are the main hazards on the S217 road?
The weather is the biggest risk. The region is prone to heavy mist and fog, which can reduce visibility to near zero in minutes. High-altitude storms can bring sudden snow or black ice, even in summer. Because the road is so remote, services are almost non-existent between the main towns. Drivers must be prepared for Altitude Sickness (AMS) and carry extra fuel and cold-weather gear.
