Hi everyone,
I will be in taiwan for around 9 days in the month of Dec and would like to travel around to experience more.
I will have to start off from Taipei and end off at Taipei.
Would like to visit Nantou's Sun Moon Lake (but is it very far? is it worth going?) and Hualian? or any other recommendations?
Could anyone please guide me?
Many thanks!

Funny you should ask that now, as David and I are trying to get a sense of people's top attractions in Taiwan.
Take a look at :

Some very good recommendations there.

Sun Moon Lake is overrated
Submitted by david on Sat, 2008-11-22 17:23.Sun Moon Lake is overrated as a tourist destination. I wouldn't say it is a must see.
There are really so many things to see in Taiwan. 9 days gives you a reasonable amount of time to visit a few different places. Start off with a couple of days in Taipei. Then maybe head to Hualian and Taroko Gorge. After that you could travel further down the east coast to Taidong. From Taidong you could take a train to Kaohsiung, spend a day there and then take the HSR back to Taipei.
I suggest you read through a guidebook or browse through this site and other Taiwan blogs to get some more ideas.
