台灣 is very 悶 if you only visit the city.
However, it is great if you travel around.
I have been there 2 times, half months each time.
I rent a car and drive to almost all the island, from the North (K.L. harbour) to the east and south part, passing the A mountain in the central.
What I can tell you is: the beach is great in the east and south part. The 'sea spring' is great in the Green Island - there are only 3 sea springs in the world, one located in Japan, one located in Europe, and one located on the Green Island in Taiwan........
There are a lot of 'protected' region for diving, with a lot of colour fish ........
If you have been there once, I am sure you want to visit there again..... like me and most of my friends.
The last time we have been there is 1 year before. Now I plan to visit Australia this summer....... However, my husband suggest to visit Taiwan again!
