The Chinese consider Chalachigu Valley, the valley east of Wakhjir Pass on the Chinese side connecting Taghdumbash Pamir, to be part of the Wakhan Corridor. The high mountain valley is about long. This valley, through which the Tashkurgan River flows, is generally about wide and less than at its narrowest point. This entire valley on the Chinese side is closed to visitors; however, local residents and herders from the area are permitted access.
