For those who have long layovers in ICN, consider taking the free "Transit Tour".

"Incheon International Airport provides a wide range of free transit tours, ranging from entertainment to lifestyle to business, temples, shopping, and tradition. Travelers can choose among the different tours available: 1-hour, 2-hour, 4-hour, and 5-hour tour courses. Each transit tour is led by an English-speaking tour guide and can be signed up for in advance online or upon arrival in the case of available seats. All tour participants must present their passport along with their flight ticket when signing up for the tour. All tours in the transit tour program are provided for free. However, tourist site admission fees and meals are excluded and must be paid individually."
