Taedo Islands, located between Hongdo Island and Gageodo Island, comprises three islands. The island in the middle is called Sangtaedo Island, the island next in line is Jungtaedo Island, and the last is Hataedo, the southernmost island located nearest to Gageodo Island. Deep and clear waters surrounding the islands make for a perfect habitat for marine life. Taedo Islands are popular for seaweed that grows naturally on the rocks, often collected by hanyeo (woman divers). People on Taedo Islands have great respect for nature and perform rituals every year on Seollal (Lunar New Year's Day) for prosperity and safety at sea.
