Sokcho is a city in Gangwon-do province, South Korea. It is located in the far northeast of Gangwon-do. Lying north of the 38th parallel, the city belonged to North Korea from 1945 until the end of the Korean War, when the dividing line between the two Korean states was officially altered. Consequently, many of the population have relatives in North Korea. The city is also a well-known gateway to nearby Seoraksan national park.
