Geumodo Island, included in the area of Dadohaehaesang National Park, has a shape resembling a big terrapin. Many fables, folk songs and folk games have been told of this island. The island features dense forests along with wild ginseng and used to be an area for hunting deer, available only to the Royal House during the Joseon period.

Also, the island is a spawning area for Black Porgy. Including the black porgy, the fishing site is suitable for other types of fish such as red sea bream, rock bream and more. 35 species of rare birds such as brown shrike, eagle-owl and more are living in the island, so it is regarded as an animal paradise.
