Gaya Mountain National Park, also spelled Kaya Mountain National Park (Korean: 가야산국립공원, 伽倻山國立公園), in South Korea covers an area of more than 80,000 square kilometers, and extends from the top of South Gyeongsang (경상남도, 慶尙南道) province to the bottom of North Gyeongsang (경상북도, 慶尙北道) province. The Sobaek Mountain range (소백산맥, 小白山脈) runs through this area. On this mountain, there are two major peaks, one of them is Sangwangbong Peak and the height is 1,430 meters but the other, Chulbulbong is 1,433 above sea level. It was declared Scenic Site No. 5 by the Korean government in 1966, and turned into an official national park in 1972.
The main attractions are Haeinsa (해인사, 海印寺), a standing Buddha figure carved into sheer rock face, Yongmun Falls, and Hongnyudong Valley. There are 380 species of plants growing there as well as 100 species of birds and animals roaming free.
Its remoteness played a role in protecting it from destruction in the past, specifically the Japanese invasions of 1592-98, when much of the country was razed. Since that time, it is said that the area around the Gaya Mountains is free from the Three Disasters: fire, floods and wind.
