So Japan and Korea are a little bit on the north, China just across the Taiwan Strait on the west.
And, on the south, the Philippines and all the South East Asia treasures ... Thailand, Vietnam, Malaysia and so on ...
Not to mention all the Pacific Islands to the East!
Also, Taiwanese use to travel a lot, so convenient flights are available for a lot of Asia Vacations destinations.
All these facts make Taiwan really a great base for exploring East Asia and the Pacific area.
This Asia Vacations page lists valuable travel websites I have found about different Asia-Pacific (and also European) travel destinations. I am sure they will give you cool ideas for your holidays in this part of the world.
