Namiseom, River island in Chuncheon, South Korea

Namiseom is a river island in the middle of the Han River near Chuncheon, featuring tree-lined pathways and various woodland areas. The place offers walking routes, rest areas, and spaces to explore at a relaxed pace.

The island formed after the Cheongpyeong Dam was built in 1944, when the river's water level rose and created this landform. Its name comes from General Nami, a military leader from the Joseon era.

The island's name comes from General Nami, executed at 28 in 1468 after being falsely accused of treason under King Yejong; a stone pile marked his supposed grave, and taking a stone was said to bring misfortune. A tour company later arranged the grave with soil and developed the island. Since 2002, when the KBS drama Winter Sonata was filmed here, Japanese visitors have increased sharply.

Ferries to the island leave from Gapyeong wharf, and a zip line from an 80-metre tower in Gapyeong-gun covers 940 metres in about ninety seconds. Walking the whole circuit takes two to three hours, and bicycles can be borrowed free of charge. The island lies 3.8 km from Gapyeong County but belongs to Chuncheon.

Namiseom declares itself the Naminara Republic, a micronation described as a tourist destination that advocates the concept of a nation. Visitors pass through its own immigration desk and receive a passport stamp, and the island issues its own currency. The 2010 zip line from an 80-metre tower in Gapyeong reaches the island in about ninety seconds.
