No, the Khyber Pass has been closed for passenger travelling.
Khyber Pass, often called Khaybar or Khaibar, is a mountain range that separates the Pakistani state of Khyber Pakhtunkhwa from the Afghan province of Nangarhar.
The pass links Peshawar, Pakistan, and Kabul and the city of Afghanistan. The range that the pass passes is sometimes referred to as the Khyber Range; it is made up of a number of dry broken hills that are the last outgrowths of the Spn Ghar (Pashto: "White Mountains") Range.
The route reaches the Khyber Hills at its southernmost point from the Shadi Bagiar gap, a few miles to the west of Jamrud, Pakistan. From there, it travels northwest for another 33 miles (53 km), to the town of Torkham, where the Afghan border is located.
The sparse Lowyah Dakkah plain of Afghanistan, which reaches north to the Kabul River, is reached after Torkham by way of a valley.
