Taiwan has lots of photogenic places, especially along the east coast and Taroko Gorge. Plenty of things in and around Taipei as well.
I was just in Taiwan for about 10 days and this time went down to Sun Moon Lake and the central area before we went over to Lukang. I am hoping to have a TR up soon. You can see the TR I did from last year's trip though.

On my trips I have used the services of Neil Wade who is a pro photographer (among other things). He knows good places to go. What we have done is 3 day weekends with him driving. He's pretty laid back so it's like traveling with a friend. Depending on your budget that might be an option. Taipei is easy to get around on your own. On my first visit Neil met me the first day and showed me how to get around town and gave me lots of ideas of places to go on my own. And then he picked me up Friday morning for our weekend trip.
