Pingtung is easily accessible by train from Kaohsiung or Tainan. You can connect to the TRA train from the High Speed Rail (HSR) station at Zuoying. You can also connect to the Kaohsiung KRT, which serves Kaohsiung International Airport. Pingtung has a regional airport but with the development of HSR, service to Taiwan San Shan airport has now been reduced to 3 times per week (Fri-Sat-Sun).
Most long-distance bus-companies have Pingtung on their schedule. You can get there from Taipei or the international Airport in Taoyuan within a few hours. It is cheaper than the HSR but still comfortable hence you usually need to change the bus only once
