Siheung Si

Siheung-si is a coastal city in Incheon, South Korea, near the Yellow Sea. It isn’t a major diving hub, and there are limited local dive facilities. Nearby dive centers and sites are typically accessible via day trips from Incheon or Seoul. The city itself offers urban and coastal access rather than direct diving opportunities; divers often use nearby coastal waters for beginner training, shore entries, or to base operations before trips to more developed dive areas along the Yellow Sea and the broader region.
