Jeju Island is a volcanic island, dominated by Halla-san (Mount Halla): volcano 1950 meters high and the highest mountain in South Korea.
The island is formed entirely from volcanic eruptions approximately 2 million years ago, during the period of time from the Tertiary in the early Quaternary period, and consisted mainly of basalt and lava. The eruption occurred in the Cenozoic era. This has a humid subtropical climate, warmer than the rest of Korea, with four distinct seasons. Winters are cool and dry during the summer, humid, and sometimes rain.
There is a crater lake that is the only natural lake in South Korea.
An area covering approximately 12% (224 square kilometers) of Jeju is known as the Forest Gotjawal. This region remains untouched until the 21st century, as the basis of lava make it difficult to develop for agriculture. Because of these forests remain untouched for a long time, has a unique ecology. Forests are a major source of groundwater, the main water source for the half of the island, due to direct rain water penetrating into the ground water aquifer through the cracks of the lava under the forest. Gotjawal forest is considered as an important wetland in the Ramsar Convention by some researchers as a unique habitat for plant species and is the main source of water for residents, although until now there has been declared a Ramsar site
