You can either drive through Irkeshtem Pass or Torugart Pass to cross the border between China and Kyrgyzstan. Osh city connects with Irkeshtem Pass and Naryn city connects with Torugart Pass, and they are both at the boundary of Wuqia county of China. Land trip to cross border is very cool and enjoyable as you can have the closest look at how the people are living at the border cites and how the custom and folklore in both side are greatly changing even just several miles away from each other.
We are experienced and professional on arranging overland tour between Kyrgyzstan and China. We have successfully escorted more than 300 travelers to transfer from the two passes. The only thing to note is that do remember both passes are only opened during working days, so passing on weekends is impossible.
