Erawan National Park in Thailand if you can get there... the Waterfall Pools are amazing.

It's quite a hike from southeast China, but I strongly recommending seeing western China and Yunnan offers a diversity of topographies, interesting sites to see. In the north of Yunnan you have the Tibetan plateau and in the south you have the jungles of southeast Asia. Xishuangbanna area is pretty great.

Ko Phangan - FULL MOON PARTY !!

Is it easy to get to Yunnan? Ive heard somewhere that Western China is not so accesible to foreigners. Or does that only apply for Tibet proper and Xinjiang?

I recommend Beijing, I hear it's a very healthy place for lungs... While you're their a visit to a factory employing child labour is very nice, and don't forget to buy snake venom and tiger balls, I hear they are very healthy. Also, sharkfin soup would be nice, you get a healthy dose of mercury AND get to ruin the aquatic ecosystem, 2 in 1.
But fk china, go to Thailand and get a sucky sucky, on your way back on the Siberian railroad, I strongly recommend a visit to a gulag. I'm not an expert so if you want to find out more PM putin33. I'm sure he knows of all the gulag (or "correctional facilities" as he like to call it) tours.

I read this as "what to visit in Asda"

Also,
Botox, you don't know shit about Thailand, your knowledge from your moms kitchen calendar of "great places" won't suffice.

just stay there on china white and smile

Accessible? It's perfectly accessible. You don't need any special permit to get to Yunnan.

I would also say Gansu is worth seeing. Again you do not need a special permit (if that applies at all it is only to Tibet proper). Of particular interest are Dunhuang and Xiahe. Fourwheeling in Xiahe was truly breathtaking.

How far do you want to go?
What do you want to see??
Asia is a freaking big place with loads to see

If you're thinking of further west in Asia then Samarkand might be worth a visit.

Agree with BrownPaperTiger. I'd give you advice, but need a bit more than 'in Asia'. Do you plan on travelling a lot? Is airtravel possible? What do you like doing? Do you consider Iran to be Asia?

If you are male, one thing I would definitely recommend is trekking. Most countries in Asia are pretty accessible, cheap and safe.

If you like food, go to Taiwan. The street food there, especially in Taipei, is unparalleled, and the local cuisine blends elements from different parts of China and Japan into a cohesive whole. It's also pretty inexpensive -- to the point that many young people don't know how to cook, because it's cheaper to eat out than to buy groceries.

OK, thanks, Putin.

I should've specified that I was mostly interested in Southeast Asia and China. Central Asia, India, Korea, Japan are off limits. Air travel is no problem, especially given how cheap intraasian flights are.

Then you should make sure you go to SaiGon for a few days. Cheap and fun.
Also, Id suggest, if you can do it, get to the Snow and Ice Festival in Harbin. That will be in full swing next month. They do one in Hokkaido, but you said Japan is off limits.
YMMV - I can't claim to have been all over Asia or anything.

Oh, and the limestone lumps round Guilin are pretty amazing too.

I will be leaving Europe on 1.1.2014 for any date related events.

I will also be doing most of the travelling (especially long-term) after the Summer Term ends, say May-July.

First week of May is a hellish week to travel in China. Trains are crammed. Don't try to rough it if you go that week (everyone is on holiday). Wound up sitting on the floor for a 15 hr ride from Shanghai to Changsha. Because I was a fool and took a hard seat.

The nice thing about Yunnan, if you decide to go there, is the weather is very mild despite being in the southwest. I went there during June & July. And it was very pleasant.
