Ganghwa Island

Recommended stay: 1 day
Getting around: Ganghwa is connected to the mainland by two bridges, so it's reached by car or intercity/local bus from Incheon or Seoul rather than by ferry; a car is the most practical way to cover the island's spread-out dolmen sites, fortresses, and Buddhist temples, since public bus service between them is infrequent.
Hours: The Ganghwa Dolmen Park, home to one of the largest and best-known dolmens (megalithic tombs) in Korea and part of a UNESCO World Heritage-listed dolmen site, is an open outdoor park with no fixed closing hours; the adjacent history museum keeps standard museum hours and closes on Mondays.

Ganghwa Island sits at the mouth of the Han River near Incheon and carries an outsized amount of Korean history for its size: it holds one of the world's most significant concentrations of dolmens (prehistoric megalithic tombs), part of a UNESCO World Heritage designation shared with sites in Gochang and Hwasun, and it served as a temporary Goryeo-dynasty capital during the Mongol invasions of the 13th century, when the royal court retreated there believing (correctly, for a time) that the Mongols' cavalry-based forces would struggle to cross the strait.

The island was also the site of repeated 19th-century clashes with French and American naval forces during Korea's isolationist period, and its fortifications from that era - along with Joseon-dynasty forts along the coast - are preserved as historical parks. Jeondeungsa, a Buddhist temple with roots dating back over 1,600 years, is one of the oldest temples in Korea still in active use. Ganghwa works well as a day trip from Incheon or Seoul for travelers interested in a denser, more layered slice of Korean history than a typical modern city visit offers.
