Ansan Si

Ansan-si is a coastal city in Gyeonggi-do, South Korea, near the Yellow Sea. It’s not a major diving hub, and there are no local dive sites listed within the city. Nearby water access is primarily the tidal/coastal nearshore areas along the Yellow Sea. With only one dive center reported and no dive sites, the city functions more as a gateway or base for divers visiting the wider region, including the nearby coast and any inland freshwater options within reach. If you’re planning a dive trip, you’d typically travel to a more established coastal destination in the area or consider training here and day-tripping to nearby sites, depending on conditions and access.
