I have been doing some real intensive research on Xinjiang and KKH these couple of days.I might push the trip back to October since thats when I graduate and October should still be autuum and the leaves are still reddish yellow and I would have plenty of time to cover that area. I think it can be broken into a few parts.....
1. North Xinjiang
where we move out from Urumqi
- if driving can drive up to Kimsar, then staright up the highway all the way to Fuyun. Then drive another 120 Km to altay.
- Or can fly str to altay also. From Altay drive on to Burqin and do the Burqin-Hemu Village(should be awesome in autuum)-Kanas-Burqin route. From Burqin, drive back down to Karamay and Kuitun. This part of the trip covers the North and will take about 8 to 10 days depending on the pace. A night accomodation at both Hemu and Kana Lake will be desirable for both sunset and sunrise shots.
2. Around Tianshan mountains
Can drive out from Urumqi or Kuitun and head west...down to Yinning and visit Siram Lake and Khorgos on the way. Stay overnight at the Narat grassland. then drive across Tianshan mountain , visit Bayinbulok grassland , Swan lake , Dragon pond on the way , and finally arrive in Kuqa . Here got one of China four largest Buddhism Grottoes – Kezil Buddhist cave , Beacon tower , Kuqa Grand Mosque and the ruins of Subashi site and then drive
from Kuqa to Korla . From Korla on the way to Turpan can visit Bostan Lake, Tie Men Pass. At Turpan, can vist Karez Well – the ancient underground irrigation
System , Emin minaret , grape valley , the ruins of Gaochang Ancient City , Thousand Buddha Caves and Flaming Mountians .
This will be one loop of its own and wil take about 7 to 8 days.
3. From Urumqi to Kashgar.
- Can take domestic flight (about 1500 miles apart)
- Take train
- Drive down from Urumqi through towns like Korla, Kuqa, Aksu etc. If stopping at the towns to explore certain regions around it, can take 3 - 5 days.
4. Karakuli Lake
From Kashgar to Karakuli Lake its 180 km and can do the trip in one day. Would be good to stay overnight in Karakuli or do some trekking aroudn the foot. 2 - 3 days.
5. South of Taklmakan Desert
From Kashgar its possible to drive on to Hotan and along the base f the Tarim Basim all the way to Louqiang, visit Ruin of the Ancient Kingdom of Loulan and back up to Korla although I havent read too much abotu here yet and whether certain sigths are worth it or open to public.
Here is a good map of Xinjiang.
