Driving the paved hairpins of Zha La: A 4.832m pass in Gyirong
Located in Gyirong County, within the Shigatse prefecture of Tibet, the ascent to Zha La is a high-altitude transit that has undergone a massive transformation. Reaching an elevation of 4,832m (15,853ft) above sea level, the road was fully paved in the early 2020s, turning what was once a rough mountain track into a modern but high-exposure highway. Despite the new asphalt, the route remains a formidable challenge for any vehicle, demanding precision and respect for the extreme verticality of the Himalayas.

How technical are the 12 hairpins of the Zha La pass?
The 15 km transit between Zhebaxiang and Kongtang is a masterclass in mountain engineering, but it is far from an easy drive. The road features 12 sharp hairpin turns that climb aggressively up the barren mountain face. While the new pavement provides excellent grip, the narrowness of the hairpins means that long-wheelbase furgonetes and heavy trucks must take wide lines, often occupying the entire width of the road. As seen from aerial surveys, the "serpentine" layout of the asphalt offers no margin for error; a single oversteer on these tight bends can be catastrophic due to the total absence of safety barriers on the most exposed sectors.
What are the hazards of the 4,832m descent toward the south?
Reaching the summit at 4,832m rewards drivers with a sweeping view of the southern valleys, but the descent is where the real mechanical stress begins. The primary hazard is the combination of steep gradients and high-altitude weather patterns. Even with the new asphalt, the road is subject to sudden ice formation and rockfall from the eroding cliffs above. The dangerous drops are immediate and unprotected, meaning your vehicle's braking system must be in perfect condition. In the thin air of Shigatse, the lower atmospheric pressure affects the boiling point of your brake fluid, making heavy engine braking a mandatory strategy to avoid brake fade during the 15 km descent.
What is the best driving strategy for the newly paved Tibet highways?
Navigating the Zha La pass requires a shift in mindset from the old gravel tracks. The smooth asphalt can tempt drivers to increase speed, but the 12 hairpins and the altitude-induced pèrdua de potència del motor (engine power loss) make high speeds dangerous. You must stay in a low gear to maintain torque on the climb and control your momentum on the way down. Watch for maintenance vehicles and local transit, as this route is becoming a vital artery in Gyirong County. In this part of Tibet, the road is a test of precision—monitor your brakes, watch the "black ice" on the shadowed bends, and never underestimate the vertical scale of the Shigatse ridges.
