Khungyami La: Driving one of the world’s highest motorable passes
Reaching a staggering elevation of 5,844m (19,173ft) above sea level, Khungyami La is an international high mountain pass situated on the sensitive border between China and India. Included in the list of the highest motorable road passes in the world, it represents the ultimate frontier for high-altitude driving, where oxygen is scarce and the terrain is unforgiving.

Where is Khungyami La?
The pass is located on the ridgeline of the Himalayas, linking the Kamba County of Xigazê in the Tibet Autonomous Region of China with the Mangan District in North Sikkim, India. It is one of the most remote highest mountain roads of India. The summit is encircled by massive snow-covered peaks and offers breathtaking views of the Khangchung Tso lake and the Teesta Khangtse Glacier, the source of the Teesta River.
Is the road to Khungyami La paved?
No, the road to the summit is totally unpaved. It is a raw, high-altitude track consisting of loose scree, rocks, and frozen earth. A heavy-duty 4x4 vehicle is mandatory to tackle the thin air and unpredictable surface. Accessibility is largely limited to the short summer season, as the pass is blocked by deep snow for most of the year. Due to the extreme elevation and exposure, you should expect brutal winds and rapid weather changes that can turn a clear day into a life-threatening blizzard in minutes.
How long is the road to Khungyami La?
There are two primary routes to reach this extreme altitude, depending on which side of the border you start from:
- From China (Tibet): Starting from Jiruxiang (Yadong County), the road is 35.2 km long. Over this distance, you will overcome an elevation gain of 1,265m with a steady average gradient of 3.59%.
- From India (Sikkim): Starting from Thangu Valley (or Thangu-Chopta Valley), the journey is much more grueling. The road is 46.9 km long with a massive elevation gain of 1,957 meters.
On both sides, the sheer altitude means your engine will struggle for air, and you will likely experience a significant loss of horsepower as you approach the 5,800m mark.
Can you drive to Khungyami La?
While the road is technically motorable, access is strictly controlled. Because it sits directly on a sensitive international border, it requires special permits from the Army and the Sikkim police/administration on the Indian side, or equivalent military clearance on the Chinese side. These permits are not always granted to civilians or foreigners. If you are allowed to visit, you must be prepared for extreme physiological stress; altitude sickness is a very real danger here. Make sure your vehicle is in top mechanical condition, carry plenty of spare fuel, and never attempt this climb without professional high-altitude experience.
