As the peak of Hallasan Mountain is made of diverse volcanic characteristics, depending on the angle of one’s view, one can feel its uniqueness. To the west of Baengnokdam crater, a steep shape formed by basalt lava of high viscosity is found and to the east, low viscosity basalt lava formed a gentle plateau. The south slope is so beautiful that it is captured in a folktale which states the story of immortals that played in the lake. Hallasan Mountain is also a mountain where fir tree forest is found which is unique of its kind in the world. At 1,400m above sea level an endemic species of cinder cones including pine trees are grown. It also possesses an outstanding biological research value in the study of cinder cones. Besides this at 1,700m, are distributed 39 different kinds of polar species which play a very important part in the study of alpine life such as the Jeju weasel, Jeju salamander, women diver snake, etc., are seen in Hallasan Mountain.

    A fairy tale like story of basaltic lava that flew underneath the earth’s surface spewed out and formed deep caves, are found in Jeju. Geomun Oreum Lava Tube System which stretches from Jocheoneup to Hengwon-ri, was formed by the eruption of a rich basaltic Geomun Oreum volcano and is situated atop an elevation of 456m above sea level. It was formed between 100,000 to 300,000 years ago and has 9 caves altogether. Among them Bengdwigul, Manjanggul, Yongcheondonggul, Dangcheomuldonggul have been inscribed as National Nature Monument. As all the tubes are exceptionally magnificent and ancient, the condition of preservation is commendable.

    • Area. 1.688 sq. km (Core area 0.518 sq. km, Buffer area 1.17 sq. km)
    • Location. Seogwipo-si
    On the east coast of Jeju is situated the 182m Seongsan Ilchulbong which looks like a grand old castle. It was formed 5,000 years ago by an underwater eruption on the shallow sea bed. Especially, the exquisite inner structure which looks like a bowl formed with a crater and slope, excluding the North West side and the repeated process of eating away and depositing by waves, all joined together make a surpassing sight. With a background the sun rising in the east beyond the horizon, the beauty of Seongsan Ilchulbong is beyond words description. That is why many people gather in this place on New Year morning to see the sun rise. The fatal attraction of the vast sea beneath a steep cliff and the white bubbles made by blue waves are so beautiful they stir up one for a moment a desire to plunge into the sea. In addition, it is also recognized worldwide as a base for researches on past volcano eruptions and underwater volcanoes.
