Rathi La: Driving the high-altitude paved road in Batang
Rathi La is a high mountain pass at an elevation of 4.689m (15,383ft) above sea level, located in Batang County, within the Garzê Tibetan Autonomous Prefecture in Sichuan, China. Also known as Rato La, this pass is a key transit point in the rugged mountains of western Sichuan.
The road across Rathi La is a recently constructed route that provides access to the remote highlands near the Genyen Massif. Although it is now mostly paved, the drive remains a serious challenge due to the extreme altitude and the technical nature of the climb, which features hundreds of tight turns and steep sections.

Is the road to Rathi La fully paved?
Yes, the road to the summit is mostly paved with asphalt, but its condition can vary depending on recent weather events. The drive is 48.5 km long, connecting Bomixiang in Batang County with Zhangna in Litang County. Despite the pavement, the road is very steep, with some ramps hitting a 13% maximum gradient. Drivers should expect hundreds of hairpin turns as the road climbs quickly into the high alpine zone.
What are the main hazards when driving Rathi La?
The primary hazard is the extreme altitude. At nearly 4,700 meters, there is a notorious absence of oxygen which can affect both the driver's focus and the vehicle's engine power. The weather is also a critical factor; sudden snowfalls and freezing temperatures are common even during the summer months. There are no services along this 48 km stretch, so you must ensure your vehicle is in top mechanical condition and you have enough fuel before starting the climb.
What can you see from the Rathi La summit?
The pass offers direct views of the Genyen mountains, one of the most sacred and remote ranges in Tibet. The road serves as a gateway for those exploring the deep valleys between Batang and Litang. It is a high-stakes drive that requires full concentration due to the sheer number of curves and the high-altitude environment of the Garzê Prefecture.
