Its jagged coastline borders the West Korean Sea and consists of more than 500 large and small islands. Diving in Gyeongsangnam-do offers an underwater landscape like nowhere else in the world. In the southwest corner of Gyeongsanganam-do, you will find the Namhae coast, where the Sobaek mountain range extends from the land into the sea. The submerged mountain range makes for a unique diving experience with an underwater topography of deep canyons and tall pinnacles to explore. Most Gyeongsanganam-do diving takes place within the Hallyeohaesang National Park.
