Dive-site story
South Ninepin Island sits on the exposed southeastern edge of Hong Kong waters, famous for its dramatic volcanic scenery. Submerged hexagonal columnar jointing forms stepped shelves, steep drop-offs, and massive tumble-boulder fields that attract oceanic life. The exposed position means conditions can shift quickly with passing swells, but the reward is topography rarely found elsewhere along the south China coast.
Submerged hexagonal volcanic basalt column formations and deep rock cuts
Large seafan sea whips and soft coral growth on outer rock walls
Swim-throughs and crevices sheltering macro life and nocturnal species
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
