The Khyber Pass, (altitude: 1,070 m or 3,510 ft) is a mountain pass connectingAfghanistan and Pakistan, cutting through the northeastern part of the Spin Ghar mountains. An integral part of the ancient Silk Road, it is one of the oldest known passes in the world. Throughout history it has been an important trade route betweenCentral Asia and South Asia and a strategic military location. The summit of the pass is 5 kilometres (3.1 mi) inside Pakistan at Landi Kotal.
