Riding Khardung La Pass: What Nobody Tells You Before You Go (17,582 ft)

There is a board at the summit of Khardung La that has been proudly declaring it the "World's Highest Motorable Road" for decades. Technically, that claim has been disputed by other roads — Umling La in the Changthang plateau now holds the verified record at 19,300 feet. But Khardung La, at 5,359 meters (17,582 feet), remains the most famous mountain pass in India, and riding it is on virtually every motorcycle adventure traveller's bucket list.

I have crossed Khardung La well over two hundred times as a route guide and support rider. In that time, I have helped push broken bikes back down the mountain, watched riders suffer AMS at the summit, and once spent a night stuck near the top when a surprise snowstorm closed the road in early October. I want to share what the pass is actually like on two wheels — without the Instagram filter.

The Actual Distance and Time (Not What You Think)

From the Leh city centre to the Khardung La summit is approximately 39 km. Most people assume this will take about 45 minutes, because 39 km is nothing. They are wrong. Plan for 2 to 2.5 hours one way in good conditions, longer in bad. Here is why:

• The last 17 km from South Pullu checkpoint to the summit involves a road that climbs over 1,600 meters in that distance alone. The gradient is steep and sustained.
• In peak season (July–August), the road sees heavy military truck traffic. These trucks are slow, wide, and impossible to overtake safely on the narrow sections. You will spend significant time in queues behind them.
• Your engine is running at a significant power deficit at altitude. What your bike does effortlessly at sea level in third gear requires second gear and constant clutch management at 15,000 feet.
• There are checkpoints — South Pullu and North Pullu — where you must stop, sign in, and present your permit. These stops add 15 to 20 minutes total.

What Your Motorcycle Does at 17,000+ Feet

Understanding how altitude affects a motorcycle engine is essential for planning. At Khardung La's summit, the atmospheric pressure is roughly 55% of sea level. Your engine is an air pump — it needs oxygen to combust fuel. With 45% less oxygen available, power output drops dramatically.

• Carbureted bikes (old Royal Enfield 350 Bullets, older Himalayan 411 pre-2023): The carburetor mixes air and fuel in a fixed ratio. At altitude, there is less air, so the mixture becomes too rich. The engine runs rough, blows black smoke, and power drops by 30–40%. You may struggle to maintain momentum on steep hairpins in second gear.
• Fuel-injected bikes (Himalayan 411 post-2020, Himalayan 450, Scram 411): The ECU senses the change in air density via a MAP sensor and adjusts the fuel injection accordingly. The power drop still happens (you cannot escape the laws of physics), but it is managed much more smoothly. The engine runs clean and does not stall.

Regardless of which bike you are on: do not try to push your machine hard near the summit. Ride steadily, stay in the gear your engine is comfortable in, and do not over-rev. An engine overworked at altitude builds heat rapidly in thin air because there is less airflow for cooling.

Road Surface Reality: What GPS Apps Don't Show

Google Maps and most GPS apps show the Khardung La road as a single line and give you confident-sounding arrival times. These tools have no idea what the road looks like on any given day. The reality changes significantly through the season:

• June: Significant sections of loose gravel and mud on the upper portions. The meltwater streams crossing the road near the summit can be substantial. Ice patches in shaded corners.
• July–August: Road conditions are at their best — more blacktop has been patched by BRO, water streams are manageable, less ice. But traffic is worst.
• September–October: Dry, excellent grip on most surfaces. The risk is early winter snowfall, which can appear without warning above 4,500 meters. If you see clouds building over the Khardung La summit by 11 AM, finish your summit visit and descend to either Leh or Nubra quickly. Do not wait around.

On the descent from Khardung La into Nubra Valley (the north side), the road is particularly loose and sandy in stretches between 4,800 and 4,000 meters. This is where most riders crash on Khardung La — not on the dramatic high-altitude hairpins, but on a deceptively easy-looking descent where the surface turns to deep sand and gravel unexpectedly. Keep your weight back, stay off the front brake, and cover the rear brake for control.

The Summit: How Long Should You Stay?

Twenty minutes maximum. I know that sounds brutal when you've been planning this trip for months. But at 5,359 meters, every extra minute you spend at the top increases your chances of a headache that will ruin the rest of your day. The BRO tea stalls at the summit sell the best-tasting hot tea you will ever drink (altitude does magical things to your taste buds) — have a cup, take your photo at the sign, and keep moving. The view from the descent into Nubra Valley is just as dramatic as the summit and you can enjoy it while moving.

Common Mistakes That Get Riders Into Trouble

• Leaving Leh after 9 AM: Army convoys roll from the Leh garrison from 8 AM onwards. If you don't leave by 7:30 AM, you will spend hours behind slow trucks with no opportunity to pass safely.
• Not carrying water: You will feel the effects of altitude more when dehydrated. Carry at least 1.5 litres of water on your person, easily accessible without stopping.
• Ignoring a headache at the top: If you feel a throbbing headache developing at the summit, do not push on to Nubra and try to sleep it off there. Descend back to Leh. You can ride Khardung La again the next day when you feel better. A headache that you push through at 17,000 feet becomes severe AMS by midnight.
• Overladen bikes: Riders who have packed their Himalayan with two full saddlebags, a tank bag, and a giant backpack often struggle enormously on the upper hairpins. The extra weight kills momentum and makes the bike sluggish to steer in the corners.
• Going in convoy without a plan: Groups of 6+ riders often become disorganized on Khardung La. Someone always gets a puncture at the worst possible spot, or one rider's bike can't keep up. Have a clear meeting point plan before you start — typically Khardung La summit for the group, and Diskit town at the bottom. Do not wait for an overheated bike at 16,000 feet.

The Other Side of Khardung La: What Comes Next

After the summit, the descent into Nubra Valley is a 74 km run that ends in a landscape so different from Leh that it genuinely feels like a different country. You come down from arctic-like conditions at the top into a wide glacial valley that transitions into warm, tree-lined villages with apricot orchards, and eventually into the cold desert sand dunes at Hunder. If you have never made this ride before, the journey from the summit to Hunder in a single afternoon might be the most sensory-rich 3-hour ride of your motorcycling life.
