Located in Yeosu, this island was named Odongdo Island because its shape resembles a paulownia leaf when viewed from a distance, and it has long been home to an unusually large number of paulownia trees. It serves as both the starting and ending point of Hallyeohaesang National Park. Covering an area of ​​125,620.4 m², the island is home to a dense forest composed of 193 species of rare trees, including camellias. In particular, the camellias native to this area grow in large colonies, leading to the island being called "Dongbaekseom Island." The approximately 3,000 camellia trees covering the entire island begin blooming one or two flowers as early as October, allowing visitors to see red blossoms even in the middle of winter. About 30% of the flowers have bloomed by mid-February, reaching full bloom around mid-March. The coast is rocky with a well-developed high sea cliffed coast, and strangely shaped rock formations with names such as Conch Rock, Folding Screen Rock, Elephant Rock, Dragon Cave, and Roof Rock. The Odongdo Island Lighthouse is located at the southern tip of the island. Vehicle traffic is restricted on the island except for authorized vehicles. Transportation options for entering the island from the entrance include the Dongbaek Train, as well as sightseeing boats and motorboats.
