How steep is the drive to Muri La?
The ascent to Muri La is notorious for its sharp gradients and constant hairpins. The road surface is fully paved, but the steepness puts a massive strain on vehicle cooling systems and brakes. At nearly 4,600 meters, the lack of oxygen significantly reduces engine power. Drivers must use lower gears to maintain momentum on the climb and rely on engine braking during the descent to prevent brake fade.
What are the conditions like at Zogqen Pass?
The pass is located in a high-exposure zone where the weather is unpredictable. Heavy mist and low clouds frequently cover the summit, making visibility a major hazard. The surrounding landscape consists of wide alpine plains inhabited by Tibetan nomads. You will see large herds of yaks and horses grazing near the road, but keep an eye out for animals crossing the highway unexpectedly, especially in foggy conditions.
When is the best time to cross Muri La?
The best window to cross is from late May to September. During the winter months, Muri La is subject to extreme cold and heavy snowfall that can block the S217 for several days. Even in summer, night temperatures can drop below freezing. Before attempting the pass, ensure your vehicle is in top mechanical condition and carry medical-grade oxygen, as Altitude Sickness (AMS) is a common risk for travelers at this elevation.
