The Chinese section of the Karakoram Highway follows the north-south Sarykol (Yellow Lake) valley just west of the Tarim Basin. The road from Kashgar goes southwest about and then turns west to enter the Gez (Ghez) River canyon between Chakragil mountain on the north and Kongur mountain on the south. From the Gez canyon the population becomes Kirgiz. Having climbed up to the valley, the road turns south past Kongur, Karakul Lake, and Muztagh Ata on the east. Below Muztagh Ata, a new road goes west over the Kulma Pass to join the Pamir Highway in Gorno-Badakhshan, Tajikistan. The main road continues over a low pass (where the population becomes Tajik) and descends to Tashkurgan. Further south, a valley and jeep track leads west toward the Wakhjir Pass to the Wakhan Corridor. Next the road turns west to a checkpost and small settlement at Pirali, and then the Khunjerab Pass, beyond which is Pakistan, the Khunjerab River and Hunza.
