What makes it special
Small Hangmun is an evocative semi-submerged sea cave sculpted beneath Beomseom's western columnar basalt cliffs. Light penetrating the cave mouth illuminates majestic rock formations.
Giant soft corals flourish along the entrance walls, while massive schools of seasonal fish seek refuge within the cave during specific tidal periods.
Dive guide
- Assess swell and surge conditions at the cave mouth before deciding to enter.
- Carry a reliable dive light and maintain single-file buddy formation inside overhead zones.
- The outer wall alternative offers magnificent columnar jointing and coral scenery without entering.
