Seogwipo Si

Seogwipo-si sits on the southern coast of Jeju Island, South Korea, and acts as a practical gateway for divers visiting Jeju. The area offers access to renowned coastal dive sites around Jeju’s volcanic underwater landscapes, including reefs, walls, and cenotes-like lava formations, with a variety of dive centers offering courses, boat trips, rental gear, and wreck or drift-diving options depending on the season. Conditions are generally cool to warm with temperate water, good visibility in good conditions, and a mix of marine life typical of Jeju, including kelp forests offshore and diverse reef species.
