The island is 73Km wide and 41Km long with a total area of 1,845㎢. Jeju island, the largest island in Korea, came into existence 700 to 1,200 thousand years ago when lava spewed from a sub-sea volcano and surfaced above the waters. Then 100 to 300 thousand years ago. Another volcanic eruption that formed Mt. Halla. The final volcanic eruption that took place approximately 25 thousand years ago created the crater lake, Baekrok-dam, at the summit of the mountain.

Mt. Halla rises in the center of Jeju island to 1950m above sea level. The rest of the island slopes down from its summit and is covered with dark gray volcanic rocks and volcanic ash soil. Relatively isolated from the rest of the world, the island’s nature has been well preserved in its prehistoric state. That is why to traveling to Jeju Island is to travel back in time.

Jeju’s natural environment was preserved as best as possible. The fantastically shaped rocks decorating the seashores, the hundreds of Oreums(secondary volcanos) and the rearest species of flora around the Baekrok-dam lake are all treasures waiting to be discovered by visitors.
