Driving the paved high road to Pe La in Tibet
Pe La is an ultra-high mountain pass at an elevation of 5,136m (16,850ft) above sea level, located in Ngamring County, within the Xigazê Prefecture of the Tibet Autonomous Region in China. It stands as one of the highest paved mountain passes in the world, offering a smooth but breathless journey through the heart of the Himalayas.
The pass is situated in a dramatic landscape north of the Yarlung Tsangpo river, the highest major river in the world. This region is characterized by vast, high-altitude plains and distant snow-capped peaks. The route serves as a vital connection for travelers heading towards Sangsang, crossing through a territory where the notorious absence of oxygen and extreme weather are constant factors. Even in summer, the thin air at over 5,000 meters makes any physical exertion—and engine performance—significantly more difficult.

How is the road to Pe La?
Unlike many other high passes in the region, the road to the summit of Pe La is entirely paved, making it accessible to standard vehicles. However, do not let the asphalt fool you; the drive is exceptionally challenging. Spanning 39.4 km (24.48 miles), the road runs north-south from the town of Sangsang, located on the iconic China National Highway 219 (G219), down to Riwuqixiang. The ascent is very steep in sections, with some ramps hitting a maximum gradient of 12%. The combination of steep inclines and extreme altitude can quickly lead to engine overheating and altitude sickness for the unprepared.
What are the conditions at Pe La?
Due to its staggering height, Pe La is exposed to some of the most adverse weather conditions on the Tibetan plateau. Sudden snowstorms, gale-force winds, and freezing temperatures are common year-round. It is absolutely essential to check the most up-to-date weather forecasts before starting your journey. The absence of oxygen at 5,136 meters is palpable, and drivers should be well-acclimatized before attempting the climb. There are no services available along the 39 km stretch between Sangsang and Riwuqixiang, so ensure your vehicle is in top condition and you carry sufficient emergency supplies, including oxygen and cold-weather gear.
