    CharacterReef dive

    Rutaki Drop Off delivers a real sense of scale. We often start in the sand channel, following it out from Rutaki Passage. The channel itself is a busy highway for resident parrotfish, and we’ve seen turtles cruising through more often than not. Once you reach the drop-off proper, you get that classic Rarotonga wall dive feel – deep blue stretching out below. Our favourite approach is to drift along the reef edge at about 15 metres, keeping an eye on the deeper water for the barracuda and tuna that patrol out there. Clouded rainbowfish dart in and out of the coral, and you'll spot plenty of ring-tailed surgeonfish schooling. Look closely on the reef face, and you might just spot a snakehead cowrie clinging on. It’s a comfortable dive, usually with gentle current, making it perfect for divers who want to take their time and scan the big blue without feeling rushed. We love it for that combination of pelagic potential and colourful reef life.
