* Geumgang Estuary Bank, a harmonic blend of the artificial and the natural * This estuary bank was completed in 1990 as part of an agricultural development project for 6 cities and counties in Chungcheongnam-do and Jeollabuk-do. The Korea Agricultural and Rural Infrastructure Corporation invested approximately 100 billion won for the project and the construction lasted for 8 years. The estuary bank can  hold up to 130 million tons of water. The 1,840-meter long bank serves a bridge that connects Chungcheongnam-do to Jeollabuk-do.Aside from being the source of water for agricultural and industrial use in Jeollabuk-do and Chungcheongnam-do, the bank also provides flood control for the area around Geumgang River. It helps keep Gunsanhang Port operational by preventing soil and sand from accumulating at the mouth of the river. It also prevents the backwash of seawater from causing damage to farmlands. Geumgang Estuary Bank has an important role as a tourist destination by connecting Gunsan and Janghang. * Plenty of attractions to see and enjoy* Geumgang Estuary Bank flows throughout many beautiful sites in Chungcheong-do. The estuary is now well-known as a bird sanctuary where the reeds and the natural habitat attract migratory birds, mallard ducks, swans, and globally rare species such as oystercatchers and Saunders's Gull during winter. An observatory was also built so people can enjoy bird watching at the estuary.Around the Geumgang Estuary Bank vicinity, nearby tourist attractions include the nation's biggest year-round sledding slope, a riverside amusement park, and the Geumgang Computer Game World equipped with about 80 kinds of computer games, making the area famous among kids and teens.
