Seopseom

An uninhabited island off Seogwipo's Bomok-dong. A site where branch-shaped hard coral, soft coral, artificial reefs, and anemone colonies come together; the relatively deep water makes it well suited to deep diving too.

A hard-coral garden
in Bomok's waters

An uninhabited island off Bomok-dong. Branch-shaped hard coral, soft coral, artificial reefs, and anemone colonies mingle over a sand-and-rock bottom. Shallow entry-level zones and deep sections (~25m) coexist, giving a fish diversity that rivals Munseom.

Entry restrictions need confirming

Seopseom (Samdo) is a natural habitat of the bird's-nest fern (Natural Monument No. 18). That protection applies to the terrestrial habitat, and whether diving entry is restricted or requires a permit is undetermined — we recommend confirming with a local shop in advance.
