Hallasan, Shield volcano in Jeju Island, South Korea.
The 1950-meter-high Hallasan summit features a 400-meter-wide crater containing Baengnokdam Lake, surrounded by basalt formations and volcanic stones.
The volcanic activity that formed Hallasan began two million years ago, with its last major eruption occurring around 3000 BCE.
Hallasan stands as one of South Korea's three primary mountains, holding Natural Monument status and maintaining deep connections to Buddhist traditions.
Two hiking paths, Gwaneumsa and Seongpanak trails, lead to the summit, while three additional routes provide access to intermediate observation points.
The mountain includes 368 parasitic cones called oreum, making it the volcano with the highest number of secondary cones worldwide.
