Odaesan National Park Wetlands

Odaesan (also known as Mt. Odae) is located in the Taebaek Mountains, the longest mountain range in Korea. It is named Odaesan because it has five big mountain peaks (O means "five" in Korean). Odaesan National Park Wetlands has an area of 1.7 hectares and consists of three small fens: Jilmoeneup, Sohwangbyeongsanneup, and Jogaedongneup. This site was registered as a Ramsar Wetlands on October 13, 2008, at the 10th Ramsar Convention.
