Incheon to portowe miasto położone na zachodnim wybrzeżu Korei Południowej, zaledwie 40 kilometrów od Seulu. Jako ważny węzeł komunikacyjny, Incheon słynie z międzynarodowego lotniska, które jest jednym z największych w Azji i stanowi ważny punkt przesiadkowy dla podróżnych zmierzających do Korei Południowej. Miasto jest także znane z malowniczych promenad, pięknych plaż i wysp, które idealnie nadają się do relaksujących spacerów. Jednym z najpopularniejszych miejsc turystycznych jest nadmorska promenada Incheon z unikalnym mostem, który oferuje zapierające dech w piersiach widoki na zatokę i pobliskie wyspy.

Dodatkowo, Incheon ma bogatą historię kulturalną, szczególnie w rejonie wyspy Munsoo, gdzie można odwiedzić starożytne świątynie i tradycyjne koreańskie wioski. Miasto zyskało popularność w 1950 roku dzięki Operacji Incheon, jednej z kluczowych bitew wojny koreańskiej. Dla miłośników współczesnej kultury, Incheon organizuje wystawy i festiwale, a lokalne restauracje serwują najlepsze dania kuchni koreańskiej, szczególnie owoce morza, które są szczególnie popularne dzięki bliskości morza.
