Sara Oreum

Located on the southern side of the Hallasan hiking routes—Baengnokdam, Dongrok, and Seongpanak—this oreum sits on the border between Namwon-eup in Seogwipo and Jocheon-eup in Jeju City. It features a rare summit crater lake, making it one of the highest crater lakes in Jeju. While the dish-shaped crater lake is relatively shallow, it has a circumference of approximately 250 meters, with the crater rim measuring about 1.2 kilometers.
