Ganghwado or Ganghwa Island is an island in the estuary of the Han River in the northwest of the country. It is separated from the Gimpo Peninsula by a narrow canal connected by two bridges. Ganghwado is the fifth-largest island belonging to South Korea, and its strategic position has brought it great historical importance in the past. This island is located at the place where the Han River flows into the Yellow Sea. The Han River flows through Seoul, the capital of South Korea ever since the Joseon dynasty. In the 13th century, when Mongol hordes were raiding in this area, the Korean capital was relocated to Ganghwado. While visiting the island, be sure to visit the 13th-century Goryeogung Palace, Manisan, the highest peak on the island, and Pungmul Market where you will find a variety of food products from this area.
