Nangpa La: Driving the unpaved border pass in Baiyü
Nangpa La is a high mountain pass at an elevation of 4,884m (16,023ft) above sea level, located in Baiyü County, in the western part of the Sichuan province, China. This remote crossing sits on the rugged border with the Tibet Autonomous Region, offering a challenging drive through the eastern edge of the Tibetan Plateau.
The road to the summit is entirely unpaved and demands a high-clearance 4x4 vehicle. Due to its location in a far-western corner of Sichuan, the area remains extremely isolated. Travelers should be fully self-sufficient, as modern facilities such as medical aid, electricity, or running water are not available along this mountain track.

How is the drive from Shamaxiang to Nangpa La?
The ascent begins north of Shamaxiang and stretches for 23.9 km. This is not a standard mountain road; it is a steep and technical climb with an average gradient of 7.80%. However, the real challenge lies in the specific ramps where the maximum gradient hits 31%. These sections require a powerful engine and experienced driving skills, especially considering the thin air at nearly 5,000 meters which significantly reduces vehicle performance.
What are the conditions of the Nangpa La road?
The track is characterized by dozens of sharp bends and a surface of loose gravel and dirt. Because of its high altitude and border location, the road is prone to rapid weather changes. Snow can block the pass even outside the winter months. Before attempting this route, it is vital to secure local information regarding the road's status and any travel permits required for this sensitive border area between Sichuan and Tibet.
