The Ganghwado Goindol Yujeok is a World Heritage dolmen site in Hajeom-myeon on Ganghwado. It holds several dolmens, from large to small, and can be walked as a loop. The northern-style standard dolmen that appears in elementary, middle and high school textbooks can be seen within 30 minutes. Dolmens under repair are covered, which can reduce what there is to see.
