Khardung La: One of the highest motorable road in the World
Khardung La : Khardung La is widely, but incorrectly, believed to be the world’s highest motorable pass. There are higher motorable passes at Suge La, west of Lhasa, 5,430 m (17,815 feet), and Semo La 5,565 m (18,258 feet), between Raka and Coqen in Central Tibet. Both these elevations are supported by GPS and SRTM evidence and the latter was also measured by the Catalans and supported by the Cartographic Institute of Catalonia. Vehicles have been driven over the 5,582 metres (18,314 ft) Marsimik La, in the Indian Karakoram to the north-east of Khardung La, but it is debatable whether this pass should be considered to be motorable.
Khardung La is situated 39 km by road from Leh. The first 24 km, as far as the South Pullu check point, are paved. From there to the North Pullu check point about 15 km beyond the pass the roadway is primarily loose rock, dirt, and occasional rivulets of snow melt. However, this pass is in better repair than many of the surrounding passes (Tanglang La, for example). From North Pullu into the Nubra Valley, the road is very well maintained (except in a very few places where washouts or falling rock occur). Hired vehicles (2 and 4-wheel-drive), heavy trucks, and motorcycles regularly travel into the Nubra Valley, though special permits may need to be arranged for travellers to make the journey.
