Dive-site story
Johnny's Gorge is one of the premier open-ocean reef sites in the Andaman Islands, situated well offshore from Havelock Island. The site features a low-lying rocky reef rising from an expansive sandy seabed, creating a natural funnel for tidal currents. These nutrient-rich flows draw substantial schools of pelagic predators and feeding rays, making the bottom perimeter around the rocky outcrop the focal point for most of the dive.
Frequent aggregations of white-tip reef sharks patrolling the sandy perimeter
Dense schools of chevron barracuda and hunting giant trevally swirling overhead
Manta and mobula rays cruising past during peak current flow

Seasonality
The Andaman diving season peaks during the northeast monsoon when calm seas and minimal rainfall provide optimal visibility.
