Outstanding natural attraction
The largest of Jeju's attached islands, it attracts over two million visitors each year because of its breathtaking natural environment. The island was named Udo Island, which means "cow island," because it resembles a cow lying down. There are plenty of things to do on the island, including tourist attractions such as "Soemeori Oreum," "Hagosudong Beach," and the canola flower fields that line the streets, as well as numerous restaurants.
