Where is the road to Muling La located?
The route to the pass is 50 km (31 miles) long, starting from a junction on the unpaved Yeban Xian Road within Zanda County. The track targets the upper ridges of the mountain range, climbing an elevation profile that leads to the pass summit at 5,556 meters before descending toward the western valleys.
Is the road to Muling La unpaved?
The road surface is completely unpaved, made of loose slate gravel, river sand, and exposed bedrock layers. The alignment contains 30 switchbacks on the main face of the mountain. The track is single-lane wide with natural earth shoulders and vertical drop-offs that lack steel safety guardrails or concrete walls. Wind and summer snowmelt cause surface erosion, altering the depth of the ruts on the hairpins.
What are the vehicle requirements for Muling La?
A high-clearance vehicle equipped with a four-wheel-drive system and low-range gearing is required to maintain traction on the unpaved mountain ramps. At 5,556 meters altitude, internal combustion engines experience a reduction in power and torque output due to low atmospheric pressure. Descending vehicles must rely on engine braking to control speed and avoid thermal fade on the brake pads.
When is Muling La closed by weather?
Sudden snowstorms occur across the Ngari Prefecture throughout the year, burying the 30 switchbacks and masking the edge of the roadbed under snowdrifts. Freezing temperatures create ice sheets on the dirt base, making the route impassable. The 50-kilometer mountain pass has no roadside assistance, mechanical workshops, or fuel supply stations.
