Getting there & away
You can buy bus tickets the day before departure from the ticket office inside customs (the office is about 1km south of Jiaotong Binguan). If you are staying at Jiaotong Binguan you can get assistance from hotel staff.
A bus takes passengers from Tashkurgan on to Kashgar (Y62, seven hours, 296km) departing at about 9.30am (Beijing time). To Kara Kul (100km) costs Y25. On departure you may also be hit for an extra baggage charge. A special hired vehicle to Kashgar will cost about Y400 and carry three passengers and luggage comfortably, stopping along the way wherever and whenever you want. Inquire with your hotel reception.
The bus to Sost (Y225, 220km) is scheduled to leave at 10.30am but usually leaves much, much later after customs and immigration formalities. If you have booked your ticket from Kashgar to Sost (Y270), you will be already on the manifest and you can hop on the bus at the Bus Station/Jiaotong Binguan for the short ride to customs. Some cyclists have been charged a ‘loading’ fee when putting their bikes on the roof, but this is highly negotiable.
