Lungdri La: The 4,689m Climb with a 9.99% Average Gradient
Lungdri La is a technically demanding high mountain pass in far western China. Situated at an elevation of 4,689 meters (15,383 ft) above sea level, this route requires maximum driver concentration due to its sustained, steep average gradient.
Where is Lungdri La located?
The pass is located in Baiyü County of far western Sichuan province, China, situated directly on the border with the Tibet Autonomous Region. The route serves a crucial regional purpose, linking two different parts of the Jinsha River (the upper section of the Yangtze River), making it vital for local transportation despite its demanding nature.
What are the technical metrics of the ascent?
The road to the summit is characterized by a sustained, continuous incline:
- Starting Point: The ascent begins at Jidong.
- Length and Gain: The climb is 9 kilometers (10.50 miles) long, achieving an elevation gain of 1,689 meters over this distance.
- Average Gradient: This results in an average gradient of 9.99%, maintaining steepness throughout the entire climb.
- Maximum Gradient: The steepest ramps reach a 17% maximum gradient, demanding optimal gear selection and 4x4 traction.
What are the driving conditions and logistical requirements?
The entire road to the summit is totally unpaved. Given the terrain and the gradients involved, a 4x4 vehicle is required. When the snow falls—which it does frequently in the winter—conditions become tough and extremely slippery. Always check the weather forecast before you start your journey; adverse conditions are common.
What are the risks of remoteness in this region?
The area is extremely remote, lying deep within the mountains near the Tibetan border. Facilities like electricity, medical aid, hot running water, or western toilets are rare to find. Travelers must be entirely self-sufficient, carrying all necessary provisions, fuel, and emergency equipment.
