Bukhan River

The Bukhan River (North Han River) is a tributary of the Han River that flows through both North and South Korea. It traverses Kangwon province in North Korea and Gangwon and Gyeonggi provinces in South Korea.
The Bukhan River's headwaters lie in North Korea near Geumgangsan; this early portion of the river is often called the "Geumgangcheon", or "Geumgang Stream." It crosses the Korean Demilitarized Zone and enters Hwacheon County, flowing south through Chuncheon and then west through Gapyeong. It joins with the Namhan River in Yangseo-myeon, Yangpyeong, to form the Han River.
