Jeju Stone Park

Stone Culture Park is a museum and ecological park that comprehensively and systematically shows the stone culture of Jeju, the land of stones. The entire park will be created by 2020, and in the first stage, exhibition halls such as the Jeju Stone Museum, Jeju Stone Culture Exhibition Hall, and Jeju's traditional thatched roof were completed and opened on June 3, 2006, 7 years after the construction began. The Stone Culture Park, where you can see the stone culture of Jeju in one place, is so large that it is recommended to visit it on a leisurely schedule. The Stone Culture Park is located in front of Oreum, a unique natural heritage of Jeju, and if you follow the shape of a castle made of piled stones, you will reach the entrance of the Stone Culture Park with a cool view of the surroundings. Passing through the entrance and following the viewing path, you will come across various stone sculptures woven from the tale of Seolmundae Halmang and her son, General Oh Baek.

Sangumburi Crater

Jeju Sangumburi Crater is a parasitic volcanic crater on Hallasan Mountain. It is the only submerged volcano on Jeju Island. The outer circumference of the crater is 2,067m, the inner circumference is 756m, the depth of the crater is 100–146 m, forming a conical cliff, and the floor area is about 8,000 pyeong. The crater rarely ejected lava; only a hole was dug deep by the explosion, and the material from the explosion was scattered in all directions and only a small amount accumulated around it. Although the diameter and depth of the crater are larger than those of Baeknokdam, the water does not accumulate and flows out to the sea through the basalt gravel layer of the crater wall. Such a crater is called a maar, and Sangumburi Crater is unique in Korea; there are only a few in Japan and Germany worldwide.
