The Salang Pass is a high mountain pass at an elevation of 3,878 m (12,723 ft) above the sea level, located in the Hindu Kush, a mountain range that stretches between central Afghanistan and northern Pakistan. The pass is the major mountain pass connecting northern Afghanistan and Kabul province, with further connections to southern Afghanistan and Pakistan.
During and after a storm the road may be impassable, even with a four-wheel-drive vehicle and can easily get muddy if it rains making it challenging to get through. The pass is the major mountain pass connecting northern Afghanistan and Kabul province, with further connections to southern Afghanistan and Pakistan, and just to the east of the KushanPass and both of them were of great importance in early times as providing the most direct connections between the Kabul region with northern Afghanistan or Tokharistan.
This road can be closed anytime when the access is not cleared of snow. The pass is now bypassed through the Salang tunnel, built by the Soviet Union in 1964, which runs underneath it at a height of about 3.400m (11,154ft).
A traveler on this road must be experienced and completely devoted to safe, slow and obstacle-conscious driving to deter danger. The road through the pass has carried heavy military traffic in recent conflicts, and is in very bad repair. Annually the total loss of life is about 40 people. The climb is simply terrible, with a notorius lack of oxygen that tests the organisms and a high degree of steepness. Most people feel altitude sickness at around 2,500-2,800 meters.
