Avanui is the deepest passage on Rarotonga and has narrow, vertical canyon walls, starting just below the surface. Visibility is usually limited to 10 to 15 metres, which adds to the passages’ natural spookiness. Together with swim-throughs and frequent strong currents it makes for an exciting dive.

A deep sand channel in the reef leading from Rutaki Passage into the drop off. You can choose to stay on the reef plateau, follow the edge of the drop-off or explore the deeper parts of the reef.
