Why Visit Ganghwado?
Ganghwado (Ganghwa Island) is the fifth-largest island in South Korea, sitting in the Han River estuary where the river meets the Yellow Sea. Connected to the mainland by two bridges, it feels like a different country from nearby Incheon and Seoul — terraced rice paddies, forested hills, tidal mudflats and prehistoric dolmens scattered across farm fields.
The island has been strategically important for millennia. Goryeo Dynasty kings retreated here during Mongol invasions in the 13th century. In the 19th century, it was the front line against French and American naval expeditions. Today, its northern shore looks directly across the estuary at North Korea, and the Peace Observatory offers telescopic views of the North.
Ganghwa is large — about 300 km2. Distances between sites can be 10-20 km. Plan for a full-day trip and consider renting a car or hiring a taxi.
