Dive-site story
Located off the High Island Reservoir East Dam in Sai Kung, this site is defined by the massive interlocking concrete dolosse that form the outer breakwater. Descending along the artificial structure reveals an intricate maze of underwater gaps and recesses where juvenile fish take shelter, gradually giving way to mixed rocky patches and sandy seabed. Water clarity fluctuates significantly with the seasons, making calm summer days the prime window for exploring the perimeter.
