Transportation from the TPE airport to NTHU (conference venue)
You can transport from the TPE airport (in Taoyuan) to NTHU (in Hsinchu) by the following ways:
1) Taxi: (takes ~1 h and costs 40-50 USD)
This is the easiest way. Taxi service is available at the airport terminals. The Chinese characters for NTHU is 新竹國立清華大學. You can print out this information and show the taxi driver. If you wish to go to your hotel directly, remember to print out the address of the hotel.
2) Public Transportation: (takes ~1.5 h and costs 7 USD)
Public Transportation is much more complex. Taiwan High Speed Rail (THSR) runs between Taoyuan and Hsinchu. But you need to take shuttle from the Airport to the THSR Taoyuan station and then take THSR from Taoyuan to Hsinchu. There is free shuttle between THSR Hsinchu station and NTHU. For details regarding public transportation, see here .
After arriving at the THSR Hsinchu station, depending on the arrival time and the location of your hotel, you may want to take shuttle to NTHU first and then take taxi to your hotel, or the other way around.
