Since Kardung La Pass is a military road, it is cleared all year round and is the highest year-round pass in the world. It is open most of the time, but during heavy snowdrifts or snowfall, buses cannot travel due to the slippery roads.
The Kardung La Pass is undoubtedly one of the wonders of Leh, but you still have to be careful. The highest point, "Khardung La" is located at 5,359 m (17,582 ft).
Staying at such heights is not without danger for people who are not acclimatized. Please be careful.
Make sure you have enough warm clothes with you, and also cover your ears and head. Take plenty of water to keep your body hydrated, as this is the only way to keep your blood adequately oxygenated.
If you are untrained or not acclimatized enough, then please take portable oxygen tanks with you. If you feel unsteady or dizzy, go to the Army Camp as soon as possible and ask for first aid.
