South Korea's third-largest city, Incheon (인천) is an expanding metropolis and industrial port. Its colorful Chinatown and Open Port areas are the most tourist-friendly parts of the city to explore, and easily accessible via subway from Seoul. Come here to eat Chinese food, discover pockets of concession-era architecture, stroll the seafront boardwalk at Wolmido and visit the fish market at Yeonan, where you can catch ferries to the West Sea islands or beyond to China.
Located 22 miles (36km) west of Seoul, Incheon is the place where Korea opened up to the world in 1883, ending centuries of self-imposed isolation. In 1950, during the Korean War, the American General Douglas MacArthur led UN forces in a landing behind enemy lines here.
