Best for intermediate divers, 15-30m, boat entry, moderate current.
The Big Cave is defined by a prominent cave structure set within a reef that spans depths of 15 to 30 metres. Divers typically experience moderate currents, which require careful buoyancy control to protect the reef structure and avoid disturbing sediment. Visibility at the site ranges from 15 to 30 metres, providing clear views of the gorgonians, soft corals, and anemones that inhabit the cave walls and shallower reef sections. Access is by boat only, and the site is suitable for intermediate divers. Night diving is an option here, with the site remaining active throughout the year in water temperatures averaging 29 to 30C.

Time your dive to arrive with a gentle incoming current, which funnels fish and nutrients toward the cave entrance and makes for the most active marine life encounters. Night diving here is genuinely worthwhile, as nurse sharks and stingrays are more active after dark.
Boat access via dhoni pickup directly above the cave entrance.
