South Sea
A warm sea heated by the warm current. Centered on Yeosu, Tongyeong, Geoje and Namhae-gun, the islands of two national parks unfold — diving that hops from island to island.
Geomundo · Yokjido · Hongdo
Islands & warm seas of
two national parks
Centered on Yeosu, Tongyeong, Geoje and Namhae-gun, the islands of Dadohaehaesang and Hallyeohaesang national parks unfold, and island and coastal boat diving dominates. The warm current keeps the water warm, and offshore-island sites tend to have good visibility. Geomundo is known for its soft coral and seahorse habitat, while Yokjido is known for its calm sea and pebble beaches.

Regional dive shops
- Visibility and water temperature are based on aggregated sources, so corroboration with primary sources is recommended. Once coordinates for Tongyeong's Hongdo are secured, the region boundary needs recalculation.
- Offshore islands are heavily affected by weather and tides — confirm departure in advance with local shops.
