I. Direction to Pohang from Incheon international airport
From Incheon international airport (ICN), there are three most common ways to Pohang.
1. KTX (bullet train) from Seoul station
Take the airport railroad (AREX) to Seoul station first:
It takes about an hour for a regular train. You can also take a fast train as well, which is a 40-minute ride to Seoul station.
From Seoul station, you can take a KTX to Pohang station, which is about 2.5 hour ride. You can make a reservation on the following website:
2. Airport limousine
It takes about 5 or 5.5 hours but you can just put your baggage and sleep.
The bus arrives at the Pohang intercity bus terminal and you can take a taxi there to APCTP (approx. 10 minutes). The time schedule is on the website below:

3. Flight from Gimpo airport (20~30 minutes away from ICN by the airport railroad) to Pohang
There are a couple of flights from Gimpo airport to Pohang airport (takes about an hour). This is the fastest way to Pohang but, unfortunately, the number of flights has reduced a lot after the COVID19. If you arrive very early in the morning, this can be a wonderful option though.
Similar arrival information and the direction to APCTP headquarter can be found on https://sites.google.com/view/dmpnp2024/direction-to-apctp which I just copied from the APCTP webpage.
