The Wakhan Corridor (, Wāxān Dahléz, ) is a narrow strip of territory in Afghanistan, extending to China and separating Tajikistan from Pakistan and Kashmir. The corridor, wedged between the Pamir Mountains to the north and the Karakoram range to the south, is about long and wide. From this high mountain valley the Panj and Pamir Rivers emerge and form the Amu Darya. A trade route through the valley has been used by travellers going to and from East, South and Central Asia since antiquity.
