Geumoreum is a nature reserve in Geumak-ri, Hallim-eup, on the west side of Jeju. From the top, the crater, the surrounding fields, and the sea in the distance are visible at once. A paved path from the parking lot reaches the summit in about 20 minutes, and at the top you can walk a full circle around the crater. The uphill section leading to the summit has steep stretches.
