학동 흑진주 몽돌해변

Hakdong Black Pearl Mongdol Beach is a Korean beach made of polished black pebbles ('mongdol') instead of sand — a distinctive coastal type found in only a few locations along the Korean coast. The 'black pearl' branding leans into the beach's polished-stone aesthetic, particularly when wet stones reflect sunlight. The beach has a unique soundscape — waves rolling pebbles back and forth — that is fundamentally different from sand beaches. For travelers seriously interested in unusual Korean coastal types beyond standard beaches, this is one of the cleaner single picks, especially as a Geoje-area scenic stop.
