About This Dive Site
A series of vertical lava-fault fissures cutting through the reef wall, Mary’s Place delivers cathedral-like swim-throughs hung with black coral and lit by shafts of sunlight. The fissures drop from 9 m to ~30 m and are narrow enough to demand careful buoyancy. Periodically closed by Bay Islands authorities for reef recovery.
