The last recorded eruption occurred 800 years ago. The island is covered with volcanic rocks. Baengnokdam, the crater and the lake inside, are located at the top of Hallasan.
Jeju is scientifically important for its lava tunnels, called Oreum in Korean. These natural conduits through which the magma flowed are nowadays empty caves, among the largest in the world. Caves offer the opportunity for scientific research and are popular tourist destinations. The numerous animals and plants present on Jeju are another reason that allowed the island to be transformed into nature reserve. Half of Korean plants grow spontaneously on the island, while another 200 Korean endemic species have been brought there.
The park is largely uncontaminated, equipped with paths forHiking and buildings for the management of the park, the only artificial objects in the area. Over 17 mammals, 198 birds, 8 amphibians, 8 reptiles and 947 insects have been found in the nature reserve.
One of the most famous points of Mount Hallasan is the Pillemot cave, a site dating back to the Paleolithic. The caves are also important for the archaeological remains found which would prove the existence of men who lived there during the Paleolithic.
