Khardung La is 40 km (24–25 mi) by road from Leh, from where a daily bus service to Nubra Valley passes over Khardung La which may also be reached by a hired car with an experienced driver or by
motorcycle.
Khardung La Road, from Leh to Nubra Valley and
Siachen, runs over the Khardung La. Since its construction, part of the
India–China Border Roads (ICBR), the route has served as a vital artery for the
Indian Army to maintain supplies to the
Siachen Glacier and as a primary conduit for high-altitude tourism in the Ladakh region. The road is often subject to long delays due to traffic congestion on narrow one-lane sections, washouts, avalanches and road accidents, but with no permanent winter closure. Updates on road conditions can be found at the official Leh site. While the Border Roads Organisation (BRO) under
Project Himank has significantly improved the surface, the high-altitude section near the summit remains subject to extreme weather, causing occasional road degradation such as slush and potholes. The road approaching the Nubra Valley is generally well-maintained, though travelers must account for potential washouts or falling rocks. The route is regularly used by heavy military trucks, hired 4x4 vehicles, and motorcycles.
Khardung La Tunnel, planned 5.5 km long road tunnel to be built by BRO of which the DPR (detailed project report) was already ready in 2026, will reduce the travel time and protect the Khardung Glacier from the vehicular traffic while ensuring the glacier-dependent water supply to the Leh city.
Kushok Bakula Rimpochee Airport (IATA: IXL) at Leh is the nearest airport. Located approximately 39–41 km (24–25 mi) south of the Khardung pass, the airport serves as the primary gateway for travelers and military logistics entering the
Ladakh Range. Daily flights are operated from Delhi. 35 km south of Khardung La. ==Tourism ==
