Avaavaroa Passage - Rarotonga

Avaavaroa Passage in Rarotonga gives you that genuine sense of adventure. We love dropping in on the outer reef, letting the surge push you gently into the channel. It’s like being ushered through a secret door. The real magic starts as you drift into those tight canyons – think Indiana Jones meets Jacques Cousteau. Sunlight shafts through cracks in the coral, illuminating schools of Achilles tang and bannerfish holding their position against the flow. You’ll definitely feel the current here; it's a dynamic dive, not one for dawdlers or heavy breathers. Keep an eye out for reef sharks cruising the deeper sections and don’t be surprised if an eagle ray glides past overhead. Our favourite trick is to find a spot to tuck in and just watch the show of fish life brought in by the water movement. This is a dive for those who enjoy a bit of pace and geological drama, offering an exciting drift through a labyrinth of coral. You’ll be treated to consistent reef shark sightings and the chance to spot turtles and eagle rays, all while navigating dramatic underwater topography. It suits divers comfortable with stronger currents and who appreciate a lively, ever-changing environment.
