Places to go in the North Sea Islands (Magong)

My girlfriend and I want to go on a 3 or 4 day trip to the North Sea Islands. We will take a flight Taipei (Taiwan Taoyuan International Airport) to Magong. The flight is about 40 minutes and will cost around 2800NT round trip.

The Magong airport is located on Penghu Island. We are planing on taking a bus or taxi to nearby Baisha Island to take an ferry tour of the North Sea Islands.

Has anyone taken this trip before and if so do you have any suggestions or comments about the area?
