Tosanbong Volcanic Cone (Mang Oreum Volcanic Cone)

Located in Tosan-ri, Pyoseon-myeon, Tosanbong Volcanic Cone (Mang Oreum Volcanic Cone) is a unique oreum featuring two horseshoe-shaped craters that together form the shape of a rabbit. During the Joseon Dynasty, this site served as a vital beacon station, exchanging signals with Jabaebongsu to the west and Dalsanbongsu to the east. It is because of this historical role as a lookout that it is also commonly known as Mang Oreum.
