Munseom Island is located 1.3km south from Seogwipo Port. It is a gateway to Seogwipo Port and it has a lighthouse. The island is protected as a City/Province-Designated Heritage. If you are standing at Oedolgae Rock, which is located near Seogwipo Sammaebong Peak Park, you can see an island that is floating on your left side. That is Munseom Island. How it got its name is also very interesting. One theory says that it is called Munseom Island because the island has many mosquitoes (“Mun” in Chinese character means ‘mosquito’: 蚊). According to another legend, a hunter’s bow case grazed the Jade Emperor’s belly by mistake at Hallasan Mountain, and the Jade Emperor was so furious that he threw the peak of Hallasan Mountain. The peak broke into two pieces, becoming Munseom Island and Beomseom Island. And the place where the peak of Hallasan Mountain was located became Baengnokdam Lake. Munseom Island is a good place to fish for red seabreams, rock breams, black sea breams, and chicken grunts. A good period to fish is from September to November. Munseom Island is a natural habitat for soft coral colonies that possess a beauty that awes divers. Corals only grow in places that are rich in plankton and where nothing floats on water. Munseom Island is a perfect habitat for corals because the sunlight reaches 40m deep into the water. However, due to recent expansion work at Seogwipo Port, pollution has become a serious issue.
