Dive Spot Guide•
Great Wall
Great Wall is a staghorn-coral wall dive in India.
Scuba DivingIntermediate
Boat access and a long coral wall make Great Wall a buoyancy-focused India dive with seagrass edges, soft sand, and slight surge to manage.
About Great Wall
Great Wall is a staghorn-coral wall dive in India with hundreds of metres of coral face bordered by seagrass and soft sand. The wall is the main feature, so the dive rewards tight buoyancy, slow finning, and respect for the sharp coral edge rather than a fast route. Slight surge can make the site feel more demanding even when the water is otherwise clear.
