The Salang Pass is nowadays the major mountain pass connecting northern Afghanistan with Parwan Province, with onward connections to Kabul Province, southern Afghanistan, and to the Pakistani province of Khyber Pakhtunkhwa. Located on the border of Parwan Province and Baghlan Province, it is just to the east of the Kushan Pass, and both of them were of great importance in early times as they provided the most direct connections between the Kabul region with northern Afghanistan or Tokharistan. The Salang River originates nearby and flows south.
