Hallyeo-Haesang National Marine Park (Hanja: 閑麗海上國立公園) is a national sea park that encompasses the most beautiful stretch of Korea’s south coast, covering parts of Sacheon City, Geoje City, TongYeong City, Hadong County and Namhae County of Southern Gyeongsang Province and Yeosu City of Southern Jeolla Province.
The word 'Hallyeo' is a combination of two islets which are Hansando in TongYeong City, Southern Gyeongsang and Yeosu City (North Korean Dialect: Ryeosu, due to Du-eum Beopchik System), Southern Jeolla. In fact, these two islets played their instrumental role as the naval base of Joseon Dynasty during Japanese Imjin Invasion (1592-1598) where TongYeong becomes as the home of Gyeongsang Provincial Western Naval Fleet and Yeosu becomes as the home of Jeolla Provincial Eastern Naval Fleet respectively.
The total area which comprises of the Sangju-Mount Geumsan district, Namhae Bridge district, Sacheon district, TongYeong-Hansando Island district, Geoje-Haegeumgang Island district, and Yeosu-Odongdo Island district is 545.63 sq km (210.67 sq mi) with 395.49 sq km (152.70 sq mi) being marine area and 150.14 sq km (57.97 sq mi) being land area. Hallyeosudo which is known as the most beautiful waterway ever has 69 uninhabited islands and 30 inhabited islands spread out across the sea like jewels. The sedimentary rocks from the Mesozoic age create a mountainous range stretched out from the northeast to southwest, and the many capes, islets, and peninsulas constitute a typical rias coast.
