If you have a connecting flight in Seoul within 24 hours of landing at Incheon Airport (ICN) and are itching to see some of South Korea, head to one of the tour registration desks in Terminals 1 and 2 to sign up for a free & low cost 1-to-5-hour city tour.
Currently, there are nine different tours leaving at various times from either terminal that cover everything from visiting the oldest temple in Korea, Jeondeungsa Temple, to shopping at the country’s largest traditional market, Namdaemun Market.
Seoul is very nice, but huge as.
