218 Country Road (S218): Conquering Buze La Pass at 5,418m
The 218 Country Road (County Road 218 or S218) is a famously rugged high mountain road located in the southern Tibet Autonomous Region of China, offering one of the most challenging drives in the Tibetan/Nepalese Himalayas. This unpaved, high-altitude journey traverses the remote Ra Chu Valley and demands maximum preparedness from all travelers.
Where is 218 Country Road located?
This remote, high mountain road is located entirely within Tingri County, Shigatse, Tibet, China. The route runs north-south and is critically important as it links the paved G318 Road near Tingri (a town often used as a base by mountain climbers preparing to ascend Mount Everest or Cho Oyu) to Zuobude Village.
How long is S218, and what is the maximum elevation?
The dirt road stretches for 89.4 kilometers (55 miles). The entire journey is defined by its extreme altitude, with the highest point being the Buze La Pass (also known as Puhrel La). This pass tops out at a staggering 5,418 meters (17,775 ft) above sea level, placing the 218 Country Road among the highest navigable routes in the world.
What are the dangers of the extreme altitude on this route?
Due to the extreme elevation of 5,418 meters, there is a notorious lack of oxygen that severely tests the organisms of both the driver and the vehicle. Most people feel altitude sickness at around 2,500-2,800 meters. The journey also presents engine difficulties, as there is extremely low oxygen for engine combustion and frequent steepness.
What are the driving conditions and vehicle requirements for S218?
The road is completely unpaved, making driving conditions highly variable. A 4WD vehicle with high clearance is absolutely required. Conditions of the road can become challenging after rain, even a single rainfall, due to mud and slippery surfaces. Drivers must watch out for sudden loose-gravel breaks and be well-prepared with equipment and supplies.
