Marado or Mara Island is an island 8 km off the south coast of Jeju, in southernmost South Korea, having an area of 0.3 km². It is home to about 90 people, and has long been known for its population being composed of strong women and docile men. It's becoming a popular tourist destination, thanks to the many unusual rock formations, and is connected to the mainland by two regular ferries and numerous excursion boats.
Mara-do is within the administrative boundaries of Daejeong Township ( Daejeong-eup) in Seogwipo City, and is included, along with Gapa Island (Gapado), in Gapa-ri, and is South Korea's southernmost point.
Because of its subtropical marine habitat the island is a natural reserve. It was designated as National Monument no. 423 (천연기념물 제423호) on July 18, 2000.
