I just arrived at Incheon International Airport. What is the easiest and most efficient way to get to downtown Seoul?
The easiest way to get to Seoul is by taking a limousine bus. The platform can be found directly outside the arrival hall at Incheon International Airport. There are buses going directly to all areas in central Seoul and prices range between 6,000~11,000won.
