What is the best way to arrange a trip to Xinjiang from Xi'an?

It depends on where you go first. If you take the bus to Urumqi, go to Tianchi, Turpan, Kulkhash first.

Another route is from Urumqi to Tianchi, then Ili and then Kana. Division

The scenic spots I recommend are Turpan, Kashgar, Kule, Perseverance, and you don’t have a lot of time. If you have the funds and don’t want to suffer, just fly. But to save your time, you can also visit more places. On average, you can stay in each place for one day. You can see all the classics. It is more cost-effective to join a group and save you money because you will have a tour guide every time you go.
