01. Mt. Halla the Highest Holy Mountain in South Korea

Name of the site. Hallasan Natural Reserve
Area. 164.401 Sq. Km(Core area 90.931 Sq. Km, Buffer area 73.474 Sq. Km)
Location. Jeju-si and Seogwipo-si
National Designated Cultural Item. Natural Monument No.182 (1996)

Mt. Halla which rises 1,950m above sea level is the highest mountain in South Korea. Baengnokdam, the crater and lake located at the peak of Mt. Halla, and about 40 oreums, a beautiful sight of steep and fantastic rock cliffs are designated in 1966 and 1970 as Nature Monument and National Park respectively, and in 2002 designated as a bio-reserve area by UNESCO. As the peak of Mt. Halla 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. Mt. Halla 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 very important part in the study of alpine life such as, Jeju weasel, Jeju salamander, women diver snake, etc., are seen in Mt. Halla. Well-endowed with natural resources of scientific values, Mt. Halla is a noted mountain worldwide.

02. 9 Lava Tubes, Geomun Oreum Lava Tube System

Designation. Geomun Oreum Lava Tube System
Area. 22.367 Sq. Km (Core Area 3.303 sq. km, Buffer Area 19.064 sq.km)
Location. Hamdeok Elementary School, Eeat side of Seonin School, Jocheoneup, Jeju-si Branch, Along the East Industry Route.

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.

03. Oreum of the Rising Sun, Seongsan Ilchulbong

Designation. Seongsan Ilchulbong Tuff Cone
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 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 of 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 that it 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 in past volcano eruptions and under water volcanoes.

Jeju Island is a Geopark

*Jeju Island Geopark was confirmed as a Global Geoparks Network member on October 4, 2010 Global Geopark

A Geopark is “A territory encompassing one or more sites of scientific importance, not only for geological reasons but also by virtue of its archaeological, ecological or cultural value,” according to the UNESCO Geoparks International Network (GGN) of Geoparks programme. The GGN program aims at enhancing the value of sites representing an earth science interest while at the same time creating employment and promoting regional economic development. The UNESCO Geopark Program works in synergy with UNESCO's World Heritage Centre and Man and the Biosphere (MAB) World Network of Biosphere Reserves. GGN, established in coordination with European Geoparks Network (EGN) in 2004, has been joined by 77 Geoparks from 25 countries as of 2011. Jeju Island was designated as UNESCO Geopark in October 2010.

The entire Jeju Island is a World Geopark recognized for its diversity of volcanic formations and geological resources. Among various sites, the nine particular sites are sought popularly by visitors. First, there is the symbolic icon of Jeju, Mt. Hallasan located at the center of the island. Suwolbong tuff ring is a well-known research site for its hydrovolcanic landforms. Mt. Sanbangsan is famous for its lava dome. Yongmeori Coast reveals a well-preserved history of hydrovolcanic activities during the early formations of Jeju Island. Jusangjeolli Columnar Joint is a popular educational site with the hexagonal lava pillars. The volume in the solidified lava shrank as the hot lava-flows from volcanic explosions cooled down. As a result, the hardened lava formations were split vertically forming its hexagonal pillar shapes. Seogwipo Formation tells the marine environment one million years ago in the excellent preservation of the shell fish fossil layers. Cheonjiyeon Falls show eroded sedimentary deposits while revealing the formation progress of the valley and the falls. Seongsan Ilchulbong sunrise peak, is known as one of the most representative landforms of tuff cone. Finally, there is Manjanggul cave. It is the only one open to visitors as part of the Geomunoreum Lava Tube System.
